Sam (Bones) Posted May 11, 2008 Share Posted May 11, 2008 here's where I'm at with my 467ci engine... since I did away with the alum rods, had to get a new crank, went with a stnd weight Scat forged w/4" stroke, and "H" beam 6.385 rods so I can reuse my JE pistons, the static compression figures out at , 11.29, my cam specs @.050 intake 258, exhaust 262 & lift, intake .707, exhaust .671, it is a solid roller. Waiting on some tools to disassemble the heads, just going to clean-up the intake ports some, and smooth out the exhaust. Going to have to run at least 50/50 race fuel/pump gas, E85 isn't out of the question yet. Been a long time since I built a engine myself, having fun with this one, rotating assem goes out for balancing Monday, having the size of the big end of the rods checked just for saftey's sake Link to comment Share on other sites More sharing options...
kc8oye Posted May 11, 2008 Share Posted May 11, 2008 hey sam... if a cam is labeled 'hydruallic roller' will it hurt it to run solid roller lifters? all the cams I looked at that are "solid roller" are just wayyyy to agressive for what I want.

Yes you can. I have have run solid rollers on hyd roller lobes for many years now. This started back in the 80's with the Ford 302 Stockers after Ford came out with a hyd roller in the Mustangs. The "hybrid" system allows for a good all around street set up. The lash is the trickest part of the deal. You need to run a very tight lash on the set up. For optimum performance I can spec out a Hybrid combo for you. Link to comment Share on other sites More sharing options...
kc8oye Posted May 13, 2008 Share Posted May 13, 2008 i'm not exactly sure what cam I'm going to use.. that problaby depends entirely on what heads I wind up with ~ right now, I'm eyballing the Edelbrock Performer RPM heads.. but i haven't set anything in concrete yet. i'm looking to get close to the 450hp mark.. 'on the cam' i'm about 350hp give or take right now.. that # comes from a h.p calculator: that 4020 is scale weight with me in it, and a full tank of gas. Quote: Your Monte Carlo weighs about 4020 pounds and can complete a 1/4 mile in about 14.342 seconds. That means that you've got about 269.33 HP at the wheels, and about 350.13 HP at the flywheel.

Guest cstraub Posted May 13, 2008 Share Posted May 13, 2008 What is the combo presently? 450HP is a realistic goal with most any BBC and still have pretty good street manners. The better the head you put on the combo the less cam you will need to achieve your power. Link to comment Share on other sites More sharing options...
Sam (Bones) Posted May 13, 2008 Author Share Posted May 13, 2008 he's running a 355 Chris, I'm sure there is a better choice for heads, I'm not much very well informed on small block stuff Link to comment Share on other sites More sharing options...
680HPStroker Posted May 13, 2008 Share Posted May 13, 2008 Sam, sounds like it starting to come together for ya. Awesome! Your cam grind isn't far off from mine. Hind sight being 20/20 I wish I'd have went the 11-12:1 route and just ran a fuel mix. HP is expensive anyway so, I say go for it. As far as heads go I say for a BB Chevrolet there are only two companies that make the kind of power they advertise. Those companies are AFR and Dart. A lot of other companies make big power claims for less money, but go to a drag strip and see who is running what. I bet it's Dart on the east side and AFR on the west side. CNC ports are also the way to go. When it comes to solid roller cams don't sell them short. As long as you don't get too aggressive you can run one just fine on the street. Just take either Sam's grind, or mine, back it off a little, and presto. You have monster power with good cruising ability. With a good valve train from the technology of today you won't even hardly be able to tell you have solid roller. Most people don't believe me when they listen to my engine and then tell them it's a solid roller cam. Like it's been said many times before it all in a good working combo. There is no majic company that can provide you with all their parts and it will out perform someone elses. Different companies do different things well. Just MHO. Peace.

Guest cstraub Posted May 14, 2008 Share Posted May 14, 2008 450HP out of a 355 is doable with a peak rpm of around 6400 or so. I was involved with a circle track program to develope a crate engine. This was a 9 to 1 engine, 650 carb, Brodix track 1 Spec heads, single plane intake, and a flat tappet cam. The engine was 417HP at 6200. Your goal is doable but I would think about what you want to do with the car because 450 HP out of 355CID is on the ragged edge of streetable. I would consider going to a stroker kit and building 383 CID. Low compression, good heads and 450HP is a a cake walk with very useable power on the street.

Heckeng Posted May 14, 2008 Share Posted May 14, 2008 Good deal on getting everything back on track Sam. Let us know how everything goes. Link to comment Share on other sites More sharing options...
kc8oye Posted May 14, 2008 Share Posted May 14, 2008 I'm aiming high on the power (450) hopefully to land about where I want to be around 400 ~ I will problaby end up going the 383 route, but not for another year or two.. the cost of an all-forged bottom end is quite a stretch for me right now. it's gonna take me all summer to get enough cash put way for the heads!

Guest cstraub Posted May 14, 2008 Share Posted May 14, 2008 For under 500 HP a csst crank stroker kit with i-Beam rods will work just fine. My circle track customers building claimer engines make 500 to 550 HP on these budget friendly assemblies and turn them for 20 and 50 lap races for seasons. You can do one of these for way under $1000 bucks. Link to comment Share on other sites More sharing options...
kc8oye Posted May 15, 2008 Share Posted May 15, 2008 i want an all forged bottom end... the possibility of being bottle fed is not totally out of the question Link to comment Share on other sites More sharing options...
680HPStroker Posted May 15, 2008 Share Posted May 15, 2008 Since we are all hijacking Sam's thread(sorry Sam) and we are talking small blocks I have an opinion(worthless as it may be). I had a 383 stroker when I bought my FGMC. It had a Scat 9000 crank, Scat forged I-beam rods, somebody's forged pistons, Dart Iron Eagle heads(with pistons compression was 9.6:1), Eddy Performer RPM Air-Gap intake, and tweaked 650 dbl pump Holley carb. I can't remember the cam grind, but it was healthy. Although I never had it dyno'd that motor had to have been close to 500HP. It would snatch my car sideways at 45mph. I kind of wish I still had it as I wouldn't be as much in the poor house. If you build this engine with a roller cam and roller rockers you will have over 500HP and with a well built overdrive tranny you will have a nasty sleeper/cruiser. When people used to hear it they swore it was a big block. Link to comment Share on other sites More sharing options...
kc8oye Posted May 15, 2008 Share Posted May 15, 2008 680hp.. that's more or less what I have in mind, but I don't plan on running a double pumper Link to comment Share on other sites More sharing options...
680HPStroker Posted May 16, 2008 Share Posted May 16, 2008 As I mentioned to Sam give the folks at AED carbs in Richmond VA a call before you buy anything. No matter what style you want they will spec one out for you based on your combo and plans and then build a custom carb just for you. Link to comment Share on other sites More sharing options...
