70 Iron

Hi Jason, he tore it apart last sunday cleaned everything and has the new lifter kit ,dogbones and all installed, He just needs to finish adjusting the valves and install the intake ,ect. He only works on it on Sunday when no one is around to bother him ,thru the wk and Sat he has his bussiness to run. I stopped by today but can't see anything,he has it up on the lift out of the way and to keep customers from leaning or scraching ect on it. I hope I have good news by Monday,I ask him if he was putting a big red ribbon around it and giving it back by Xmas,He grinned and said I hope so! I'm glad this all happen after the car shows and crusin ,I'm not in any hurry but would like to know if this fixed the problem. Thanks I sent the Comp lifters back to Jegs and they gave me a refund for them. no questions asked

Gotcha Larry, I did a blank several yrs ago for a 70 SS Chevelle,it was hard to find all the RPO s and the prices then,it took awhile but I did get them and had my Daughter type it up. I copied alot from original ones from the car shows.

Larry,when you apply for this, a list of RPO options for your yr monte comes up and you check the ones you have.He will not except any "Rare" options (like LS6 )ect or add ons without proof

Try www.window-sticker.com I had one made 2-3 mo ago He was at that time 6-8 wks behind ,he does this on the side If anyone would like a repo state inspection sticker from your yr of the Monte even Canada www.inspectionsticker.net

Hi Scott,thank you very much for your generosity,you are very nice to offer your prts,I deeply appreciate this. The lifter kit should already be at the shop though. I'm stopping today to see if he started the replacement of the lifters. Yours sound just like these,The "Dogbones " and all ,but at this point I'll just go with these.They had to be ordered special from GM.Thanks again for being so thoughtfull. I'm hoping this will be the fix. Terry

Thanks Jason for this great info,I remember your 1st post and suggesting this could be your problem,I have been giving all this info from all of the replies to my guy at the shop.The block info was great . Just to repeat my self,the first block started missing badly and sounded like 2-3 lifters had lost its prime ,it went away when I run the RPMs up to about 3000 then about 100mi or so came back but never straighten out again.The lifters were very quiet all along until this missing and sounding like collasped lifters. The second engine after the valves were adj at startup were also quiet until the same sound and the engine missing came in around 1300 miles.Both engines had a light tap under load but couldn't hear it at idle. Since the changing of the cam,springs.lifters and chain/pulleys the engine just sounded like the sewing machine as described above but wasn't missing,just noisy .I'm hoping this change to GM lifter kit does the trick. I was talking to a friend today that has a noisy lifter engine,it was a 402 BB 71 Monte.It also had a aftermrkt cam /lifters. He only bought it to flip though,I was considering it but it slipped away,it was a factory 402 with A/C,buckets ect.He traded it on a older truck. Thanks again fellows,I'll let you know what the out come is after the change. Terry

Thanks guys, We just decided to order the lifter kit from GM prts,these lifters are seperate not like I have with the link that ties 2 together. Also they have the girdles. As I understand these link together lifters are made for top racing ect and will be a little noisy ,A Friend /Engine builder of my mechanic have discussed this problem and changing to the seperate lifters/girdle kit is the way to go.At this point I'll try any thing.Its one of the cheapest things to do at this point. He's thinking that the after mrkt lifters are slightly smaller in the lifter bores and only GM will fit the best and quieter. Will let you know. Thanks guys Terry

Sam,you also have the BB don't you ? On a scale 1-10 how noisy is yours ? I'm having him bolt it back up and I want to drive it a few days .just want to see how its running and let the noise go ,then decide whether to change the lifters back to GM,I didn't have "This "sound before the Comp lifters,It sounded like 3-4 collasped lifters and engine shaking (Missing ) now its idling ok but extremly noisy,too ashamed to take it to a show . Terry

Thanks Mac, This is a steel Roller cam so the breakin is different from a flat tappet, but it was well lubed and every thing seems to be in line ,push roda centered in the guides ect.we did treat it a little like a flat tappet and kept the rpms up until we heard all the noise so we shut it down before any more damange could happen. As I said above,we went to O lash and heard the clicking then turn it 1/2 turn and up to 1 full turn ,the clicking went away with finger tighting the adj nut "BUT" the loud hollow noise from the valve train would'nt get any better from 1/8 turn to 1 full turn just didn't make any difference no matter how tight you made them. I called Jegs about the problem and told them I wanted to return them ,I'm thinking about going back to the GM lifters. Thanks

Hi guys,I went down to the shop today and here is whats going on. I had him do a lash adj hot and running ,just to be certain where the push rod is and not depend on the finger turning the push rod,the old school where I understand ect .He loosen the adj nut and lock backed it off until you begin hearing the clicking and adj 1/2 turn down on them all ,did all the right bank. they all sound like a sewing machine ,we then took them another 1/2 making it 1 full turn and still no change. Now don't get this mixed up with the click you hear at 0 lash ,they sound very noisy like on a 1-10 they are a 8 or better.I know you should hear them slightly being a steel Hyd roller cam,roller lifters that has the link on them (tying 2 together) and aluminum rockers.I used all new comp cam prts ,cam,lifters,behive springs (which were on )gear and double chain.These can't possibly be made to be this loud ? I had him back them off to 1/2 turn which makes no difference from 1/8 turn to 1 full,again this isn't the "o" lash sound but a loud hollow much worse then any soilids that I ever heard. At this point I told him to bolt it up and I'll bring it home out of his hair,its been very flustrating since day one with this engine. I'll think about whats the next option with this,I right now plan on taking it to GM to hear but don't want to tell them that I replaced the GM prts with comp,I just want them to hear it and put the ball in their court,I spent a lot of cash trying to fix it . This engine is the crate ZZ 427 and it has the retro fit rockers ect.Aluminim heads. To close,just want to say that when this lifter problem started I had 1300 miles and it sounded like 2-4 lifters clasped,and would pump up and loose prime again a off and on but more on then off keeping me from driving it ,now after we changed all of the prts as you read above it is now noisy all over on both banks but not missing like it was.Its almost like the lifter were made this way to make all the noise.I'll call Comp tomorrow and see what they have to offer. I'm wondering if I changed the lifters back to new GM prts if it would make any difference. Also wanted to note that there seems to be plenty of oil pumping from all the push rods Thanks, Terry

Thanks guys for you advice and I'll share it with him today when I go down.He suggested turning then down but wants to wait until a friend engine builder of his stops by to hear the problem first. Thanks for your help ,I value your opinions/advice very much. Anything else you think of throw it out there ,thanks. I'll let all know what comes of this. Terry

Both banks

Yes Sam ,It started all at once,I left it ide for awhile and it went away I drove it a few miles and it started again when I was pulling it in my garage.

Thanks Sam,I'll make a copy of your suggestions and give it to him. Would it run quiet for 1300 miles if this was the case? He did prime the engine and the oil was coming out all the push rods he even turn it by hand 180 and primmed.

Sam, on top behind the intake,there was a plug in the block not where a SB woud go but below a little.It read 60 lbs cold ,didn't want to run it until it it heated up because of possible more damange. I used an electric type there and the orig down by the oil filter He also checked it there with a gauge and it read the same as the top Terry

Sam to answer your question ,they are all GM wires ,cap,dizzy ect. Also its not one of those caps that seperates Right and left but the old way 18436572

Sorry about the repeats,I couldn't get it to post

Sam ,this new replacement came with all new ignition ect, and heads I didn't use any of the prts from the first.Thanks Terry

Sam,just wondering how the ignition could make about 1/2 of the lifters sound loose off and on ? Not disagreeing now Sam lol. This new replacement 427 came with all new wires ,plugs,dizzy, heads ect.It did last for 1,300 MI . Terry

Sam,just wondering how the ignition could make the lifters sound loose then quiet ? Not disagreeing now Sam lol. Only about 1/2 of the lifters sound like they loss prime. thanks,Terry

Thanks guys, I'll be waiting for a couple of days to come up with a fix then I'll trailer it to a Gm dealer to hear it run before we remove it,then I'll drop it at their door step . I may have to remove the Comp prts before I give it to them. Don't want to give them a loop hole. Terry

Hey Guys, Need some opinions , As some of you know I bought a New GM 427 Big Block Engine last yr,I had 2300 miles on it and it started banging missing ect from the valve train along with metal pcs seen in the oil also sucking oil 2 qts to 500 miles.,Gm replaced the engine and paid for the install. This new replacement has 1300 miles and it is doing the same , The noise is like collasped lifters maybe 3-4 of them along with missing popping ect from the tailpipes.You can sit and idle and it will clear up for a few second to minutes and start again ,you can't drive it anywhere . We called Gm and they don't want to hear it since its the second ,won't return calls ect, my guy at the garage is handeling the problem since the engine came thru his garage. We were at a standoff so I decided to pay my guy to tear it down and install new lifters also inspection . After the tear down he saw that the cam had a path already worn on the lobes !! How ?? it only has 1300 miles of easy driving .So now that we open a can of worms I bought a New Steel Roller Comp Cam with matching lifters , new springs ,timing gear and chain all Comp parts.Adjusted them down 1/2 turn like the specs said with the new Cam. Now here's the B-t-ch,It still has the same problem !! right from startup,He primmed them until oil was coming out of every push rod and lifters were pumped as well. We installed a oil pressure gauge on the top of the engine and the bottom and they read 60 lbs cold,we wanted to be sure if it did this again we could read the top gauge pressure so its fine.I called Comp cams for some advise but they had no answers.I just can't beleive its still doing the same thing. I / we will be pulling it soon if we can't find the problem and will be Reinstalling the original SB 350/300 ,this has been going on since last Nov with 2 engines ,I bought it last Nov on my birthday and its been" H" ever since,I'm out of patients (and money). Do any of you have any opinions what to try next ? This engine is the ZZ 427 ,I also went with a cam simular to the orig one that came in it,just a little more dur,Lobe centers are the same and the lift is very slighly less. Both are steel Rollers. Any advice ,opinions will greatly be appreciated (and Sympathy) Terry

Thats Great Tony Sounds like you have a head start on the winter projects. You need to erease that single tire burnout in your driveway and in front of the house and lay down some posi burn outs just to show the neighbors Is it true that Ali got to do the first posi power launch Terry

Auto Zone up here has a great selection on A/C seals,I bought the 2 O rings that go on the rear,they are green and work on R12 or 134,also bought a pack of assorted seals there too. Terry

Who is that guy thats sneaking around behind that Vodka bottle ?? Very nice award get ready for more in the future.Nice place to call home.Maybe you need to have a special room for them Wish I could make it but this old body is shot by evenings Terry
