4.0 SOHC Performance Motor Build

[Limited02]

Well you answered my question I think if you can round up a stout rotating assembly, P&P your heads, small cams with good valve springs, you should be able to build a stronger and more efficient motor that will more than meet your needs. Bump up to 12#'s and be running low 13's all day

I know what I mentioned sounds easier said than done, but you don't need the bestest of the best for your motor. Just whatever it takes to reach the power you have in mind.

The SBC rod option will be the most cost effective solution and I'll more than likely go this route.

Here's some pics of some powder coated parts I have laying around waiting....

Can you guess what the last pic is for?

Chevy TPI motor. Duh! That was easy. (watch, now I 'll be wrong.)

 

[Jakee]

Yes, you're correct. Thats the next project that keeps messing with this one. I'll be running twins with a 4 bolt main 350 CI block. The engine is going in a 88 s10 4wd blazer. THe 4wd will be gone but this should be one torque monster and will be a track only set-up. I want to pop wheelies...hehe

Since this is up top, let me give an update.

I've done nothing but tear the engine down. Everything went on hold right before I went on vacation in California and spent all my money - I'm broke and I'm nervous about spending this sort of money with the way the oil field is right now. I'm not sure when I'll get the opportunity to do this and have considered canning this project and starting a more cost effective approach.

if you DO can it.. i'll me more than happy to take the parts off your hands

Well, it would get in the way of the wheelie deal, but wouldn't keeping the 4wd help you get all that power to ground and get off the line quicker?

I'm hoping to eventualy build a twin-turbo TPI myself, for an '84 Monte Carlo w/ T-tops, and (when I'm done with it) and aerocoupe rear window. I'm guessing a cage will be a good idea, considering the lack of substantial roof structure. I've also got a '79 Impala 2dr, with the "fastback" style rear glass. I hope to build that into a street-legal Winston Cup look-alike, or at least a real serious road race style car. Of course, that's all after I hit the lottery, or get a decent job. Not sure which will happen first...... lol

I'll post some pics of my friends monte carlo - I think you'll like it.

The 4WD would help get me off the line but I don't think it would hold very long with 600 HP. If I could find an AWD transfer case that would hold up, I would go this route.

 

[techieman33]

Didn't the typhoon have an awd transfer case?

 

[Jakee]

Yes, but it held up to 400HP. Even then, there were problems.

 

[techieman33]

there is always the 4405, but I'm not sure that anyone but possibly troll has run one making that much power.

I'd look into the Syclone/Typhoon drivetrain for that S10, Youtube is full of those trucks running very fast and beating high end cars. What about the transfer case is suspect? Those trucks run 13 seconds stock, and it sounds like they see 11's without much work.

 

[pazzo1969]

hey Jake, instead of flooding this post with my pics i'll post the link for your friends. all the turbo pics are on the main page, towards the last 4, like 12 thru 16. excuse the mess, just been to lazy to clean it up. lol mike

Back when these trucks came out, a bud of mine bought one new. I rode with him many times and yes the truck is darn fast. 13 seconds stock and 280 HP (I think). He managed to break the tranny two different times before selling. I'm sure there's something that can be done to make it stronger.

Pazzo1969 - You have a bunch of knowledge in this subject. What's the best tranny option for the 350CI twin turbo'd project?

 

[CDW6212R]

Weren't those the 700R trans? Those I gather have minor issues in stock form, but they can be made to take good power. I think they are the equivalent to the 4R70W trans.

These are all pics of Mike's (pazzo1969) Monte.

Very nice, the slick frame too.
