its getting to be that time, my 94 is getting up in miles and winter is coming. so whats everyones view on going to a 331 or 347? i will be using my block, but after that, aftermarket. and who has the better kits? my futture motor, afr 185 heads, 1.6 rollers, custom cam , trickflow track heat intake,( i have already 24lbs injectors, 75 mm throtle body, 75mm maf, bbk 1 5/8 equal leangth headers already.) also on my mind is a supercharger, probably vortec.(will swich to shorty headers after supercharger) so this is all must be in consideration when looking for the right kit, 331 or 347?? also have for trans a t5, and 373 in the rear end. ok now its up to you, what do you have to say?
