Stroking an LS1
#11
ok david but how do you get there?
also, is the bore of the ls1 smaller than the bore of the older 350's? i bought some new pistons for my old 350 the other day and just for giggles stuck one up to the cylinder on my ls1 on the stand, and it wouldnt go in. Is this why they are a 347 and not a 350?

if not mistaken a 4" crank and 6.125 rod will get ya to a 383
i'd run a 10.5-8.1 cr
or possibly try and get to 11:1

with that said: my mods consist of a stock lq9 short block, ls3 heads ported with light weight valves, a nice little 235/239 cam,ewp, fast 102MM intake and 102mm throttlebody with kooks 1 7/8 to 2" headers through dual exhaust, set up with a level 2 performabuilt tranny with a 4 link on a stock 10 bolt with a trutrack and soon to be 4:88 gear

Give me a ring this evening Nick. I've done some brainstorming on this situation
I really hate to hear about those bad parts, but if you were considering building it up right from the get-go it just made the decision for you!
