Looking at my sig how much of a diff. will it be between a stock bore high comp piston vs a 416 kit, i am debating between these 2, i will also be adding a stg2 hotcam also! I would like to stick to stock bore right now so i can put the extra 50.00 into some more work on my porting? Is there a big noticable diff. or should i get soem decent power from stock bore hc piston??

if they are the same compression no you wont notice any difference. there is maybe a 0.5 HP difference but you wont feel that at all. my buddy has a 416 and i have the stock bore with the mods below and i beat him all the time. and we both have about the same amout of grunt off the bottom just seems like mine revs faster. he has the same cam as me but i have more head work done.i would put the stock bore in and put that extra 50 into some head work. really you don't go faster with more CC's its the higher compression and the faster you can get gas in and exhaust out will make your quad faster.
