Street LT1 rebuild
Hey guys!
My stock 350 LT1 Camaro 1995 with 87k miles threw rod bearings on the 1st and 8th cylinders and a main bearing also blew. I am considering building a 383. This car is purely a street car. Any suggestions on rotating assemblies?

You'll have clearance issues...
Why are you afraid to over bore. It would be best to bore and hone it .030" over to have fresh concentric cylinder walls to seat your new rings against. You'll want to have your block align honed and cut/polish the crank if it's salvageable. Otherwise pick up another good stock crank. Recondition your stock rods and install ARP rod bolts. Pick up some Mahle 4.030" hypereutectic pistons (or forged alumn if you have the $$$). That will make a nice 355 that is good enough to handle your purely street car.

the entire 383 kit will cost a WHOLE LOT more than boring your cylinders! Overbore really is not THAT bad, especially if you take the block to them already disassembled because that makes less work for them.

mine before I tried my cam swap destroyed slightly modded LS1's.
I have a 355 with AFR 187cc Heads, Exhaust, Intake, 52mm TB, MSD Ignition, Headers, and some suspension mods. I raced a 2000 Z28 with CAI, and Exhaust. I beat him off the line and I was pulling on him the entire race, even on my top end in 3rd and 4th I was pulling away.
I have alot of mods, but that shows you what an LT1 with just an overbore and bolt ons can do... Once I finish my cam swap that will be another story
