Reaper

I need to start thinking about what I want to do for real.... either beef up the 12 bolt or start building a 9" I like the thought of a 9" just because its a lot easier to change the gears... Could use one set of gears for everyday cruising around or whatever and then another set of gears for when I want to play at the track... but its not that important to me as I will probably just run something around a 3.42 rear gear. I dont think Ill need anymore than that at the track and its not to bad on the street. Another thing with the 9" is no c-clips.... yes I could get c-clip eliminators but Ive heard that they can leak if you drive a lot on the street. I like the 12 bolt because its a GM rear and Id like to keep it... Not to mention it would save me some money on buying a 9" housing... What all do you guys think would seriously have to be done to the 12 bolt to run 9's with a supercharged big block? Not to say that I will be running 9's but just incase I ever do try for it... A friend of mine and I are in kind of an ET race... Would I have to do anymore than; welding the axle tubes, girdle rear end cover, after market axles (what spline do you think?), 1/2" studs, c-clip eliminators or 9" housing ends (What do you think would be best?). That is all I can think of... anything else I might have to do? When I do put a supercharger on the 460 Im gonna be trying for about 750-800 HP.... To give you more of an idea.... Thanks, Tom

I have a loop in the garage... Just dont have the motivation to put it on yet... I want to drive it as much as possible before winter gets here... When winter does come I have a lot of work to do....

Im not to bright sometimes... Build an engine with some power and basically forget about the drivetrain before I start playing...

Everyone always worries about the rear end and transmission and no mind really gets paid to the driveshaft that I have noticed... Does anyone know how much abuse a stock drive shaft can take? What kind of material is the next step above stock? thanks, Tom

Very nice One of these days I might need one of those... When I started building my car I wanted it to be a sleeper, a cage kinda gives it away Then again, the way my Monte sounds doesnt exactly hide that its fast... Tom

Cool! That looks like way to much work

Is that dyno rear wheel horsepower? Might be a dumb question but just curious...

Thanks guys I think I will get the transpak. Straight manual valve bodies do suck to a point... I use to have a 71 Chevelle and the trans went out on it. We had one out of a car that we never drove but was told the trans was good, so anyway we put this trans in the Chevelle and I started the test drive. Drove around for about 20 minutes trying to get it to shift into second, was checking things out jumping on the gas blah blah blah. Eventually I though Ill try to shift it myself just for the hell of it and bam second and third I went Ended up getting a speeding ticket as soon as I figured it out.... Oh well it happens. After about a week though it did get old, I kept forgetting to put it back in first and had to stop do it right, if I tried to goto first while the car was moving it wouldnt shift to second. Anyway it did get old so if I did do a valve body it would prolly be a auto/manual. I think I would be a little better about remembering to shift with the Monte but its prolly best to have a manual/auto anyway

Summit add makes it sound like its somewhat of a rebuild kit... Is it all stuff I can do myself in the garage with common tools? Thanks guys!!

Hey, just wondering I have a turbo 400 that is gonna be in my Monte behind my big block... gonna be a strip/street car I dont mind shifting the gears myself for the manual valve body... What would be my best bet.... Manual valve body, Manual/Auto valve body or a shift kit or valve body and a shift kit? I dont know much about trannys... any ideas? Thanks, Tom

Damn.... guess Ill just stick with the bolts unless I win the studs I already bid on.... thanks a bunch guys

Would I have to have it honed if I added just ARP main studs?

Do you guys think this is worth it? Ebay item # 260087585787 Its $75 bucks plus shipping and comes with some studs. Also if I did get this would I have to worry about any clearances with my 454? Thanks, Tom

So a 550-600 hp big block should be ok with them even if I put a 177 supercharger on it? (3 pounds of boost) Thanks again. I was hoping they would be OK because the engine that my dad is giving me has them in it and I dont wanna HAVE to buy pistons....

Just wondering how much Hypereutectic pistons can handle.... Are they anything close to Forged? Thanks, Tom

Very helpful Thanks!! I will deffinetly be going with one..... Seems like win/win.... I am gonna go with a 3.73 rear gear so I should get pretty good RPMS on the highway too.... cool Im loving that thing.... Can I get a loan from someone?

Just curious if you can manually shift it through 6 gears or can you not shift through the 3 of the gear vendor? How does it work like that? You know what I mean.... this looks kinda confusing as Im typing it... Thanks, Tom

6000 miles and still going is a lot better then I thought you were gonna say

How many miles you figure drag radials are good for? guesstimate

Giving up two or three miles per gallon isnt that big of a deal for not breaking my trans every year.... Maybe in a year or two Ill get a gear vendor and be good

Im hoping to be in the 11's myself... what kind of suspension are you guys running? Also rear gear? Thanks, Tom

Yeah I know about the gear vendor but very expensive. I want the tranny to handle what ever I can throw at it. I will prolly end up building my th400 and saving for a gear vendor.... Sounds like a reasonable idea Thanks

The more and more I look at comparisons between a th400 and 700r4's Im thinkin Ill just build up my th400 and possibly save some headaches.... What kind of gas mileage you guys think a 700 might give vs the th400 as well as track times.... Thanks again Tom

Do you guys know what a 30 spline 700r4 with upgraded servos and clutches would hold up against? Will be around 600 HP hard ran..... Should I just eat the gas mileage and build my TH400? Thanks, Tom I have a big block by the way.... and street/strip with street slicks....

K thanks I know some have dual patterns but this one doesnt... Theres a TH400 on ebay that has titanium gears and shift kit and all the works but its Olds.... Ill prolly just build mine... Dont really need titanium anyway...
