I'm picking up a 350 TPI engine soon and I'm trying to figure out what to do with it. The engine was just rebuilt, in fact, it's still at the engine shop now. The block and heads are both from a '92 Trans Am. Here's what's been done to it:

8.0-8.5 comp. forged pistons (.030 over)
Pete Jackson gear drive
Comp cam .462 lift
Crane 1.7 roller tip rockers
Accel SuperRam
Vortech S-trim supercharger w/aftermarket pulley approx. 10-12 lbs boost
MSD boost retard

I'm trying to figure out what to do with this engine and don't really know how much power to expect. I was thinking in the 450 to 475 horse range. What do you think?

 

Why 1.7's why not just get a diff cam to make up for having to worry about valvetrain geometry.

and I think the bigest limiting factor would be the stock heads.

 

Yeah, I'm sure the stock heads are going to be the weak point. I didn't have the engine built so I'm not quite sure why he went with the 1.7 rockers but I guess he just wanted a little extra lift.

 

my suggestion is to weigh each of your TPI equiped rides and put it in the lightest one

 

Actually, I'm leaning toward just putting it on eBay right away and see what it sells for. I'd like to keep it and put it in something down the road but I really don't have the space to keep it around for too long. However, if I had a little better idea of what kind of power to expect I may decide to keep it.

 

Id just put some better heads on it man. Sounds like a nice setup beside stock heads on a motor build for boost.

 

sure, but there are lots worse heads than a set of stock L98 irons

 

well if you do seside to sell it or PART IT out.. Drop me a e-mail on the superram

but for how cheap some pro toplines are or some darts. hell Sell your stock motor get heads for this one and have fun.

 

Like what? for a performance application I suppose that you could make the argument that the swirl ports from the same years aren't great, but they're really no worse. Just about everything else is better, fresh out of the junkyard…

 

I guess I was thinking more along the fact that GM used them on the "original" crate motor.

 

If you keep it, get rid of that gear drive. They screw up your timing.
