1985 Silverado LQ4/4l80e Turbonetics Single Turbo, 60lbs injectors, air to water intercooler, PST driveshaft, ARP head & rod fasteners, Custom cam, HP Tuners, PLX wideband, DUAL tanks still work!
3.905" bore off the top of my head.
a 4" crank would work also.
should be approx. 383ci
11' Sierra 6.2 NHT
14.46@91 Stock
89' Mustang LSX
10.35@130 pump gas LQ4
Knothead Racing
3.908 is what I was thinking. There is a 4.100" crank available from Eagle for the LSx engines. The aluminum block is a lot easier to grind rod clearance for, also.

I didnt ahve to clearance any at all on my iron 6.0 block for my 4.100 stroke. The LS1 block needs ALOT of clearancing on pretty much every cylinder wall, the sleeves on the aluminum block go down alot further then cast walls of an iron block. 3.905 is the "standard" LS1 over-bore size. Remember you cant just buy pistons and slap on your stock rods unless you buy the heavy ass Diamond pistons with a .945 wrist pin diameter most aftermarket is SBC size of .927
