My original plan for getting up to freeway speeds on my C20 was install a T5 tranny along with a 3.90 in the rear. I just scored a 350 long block which I think will replace the 292. I plan on building the 350 for around 250hp. What 4spd or 5spd can I use that will accomplish what the T5 would have? Will a T5 from an S10 hold up mounted to a 350? I liked the S10 T5 'cause the shifter's only 7 inches or so back from the original and no seat modification would have to be made. Basically, I'd like my interior to appear stock and unmodded.
