350 engine with stock 5 speed tranny
 

I want to put a stock 350 4 bolt in my car. Are there any upgrades I need to do to my stock 5 speed tranny?

My $0.02: No. Wait till/if it breaks then deal with it then. Drag radials/slicks may be a bad idea.

no point upgrading the t5. so long as you use the clutch, dont powershift, no high rpm clutch dumps, the t5 should survive as it is. You can swap it for a WC t5, its a little stronger, not much, but still cheaper than a t56 swap or a tko.

Thanks!

FYI i broke a world class T5 with a stock 302 and street tires...something to keep in mind

dont powershift it :lol:

and just to throw it in there, 88-92 T5s are WC.

im not sure what year your iroc is.
