TH350 rebuild questions

[Arrythmic_mike]

I am going to go through a TH350 and do a good rebuild on it. Anyone have any sugestions on what parts and where to find them(A catlog perhaps) to build it to handle 500+hp?and what size stall should i get. the cam is a crane powermax hyd roller, int duration 234 exh duration 242 lift is int .539 exh .558 3,000 to 6,500 rpm range.

Let me begin, I am not a expert on engine rebuilding but, will give you a general guide line....A 350 in3 engine producing more than 400 hp will not be pleasant to drive daily on the street.

If you want a streetable 350 look at the components in a zz4 engine. The crate version costs around $3800 complete w/carb.

Engine experts step in....BTW-I buy all my parts from Summit or jegs.

With that high horse engine your stock type sprag won't last. You will want extra clutches and other hi-perf parts. Try these guys. http://dragtrans.com/Racing-Transmissions.html or these guys www.bulkpart.com

First off LT1 im building an engine but needed input on how to build up the tranny to handle the large engine. This will not be a daily driver btw, its just going to be a toy. Thanks for the input. Mike..

JMO if you've got a good trans. id put a good shift kit in it and try not to jerk it around to much and go for it. if it needs a rebuild id add a few extra clutch to the clutch packs and put in a good shift kit and try not to jerk it around to much. a trans will stand a lot until you start abusing it. may need a good stall conv. before its all over with.

you need to see what cam, intake, gear ratio and a few other things you are gonna run before you get to the conv.

the cam is a crane powermax hyd roller, int duration 234 exh duration 242 lift is int .539 exh .558 3,000 to 6,500 rpm range. The intake is a super victor single plane. with a mighty demon carb. gearing ill need help on eventually when i find the car, right now im just trying to get my power plant ready to go.
