What does that equal at the motor? It would take me a while to figure out it is a LS under the hood, looks good. Unfortunately your bottom end issues are common to 455 builds, which is what lead to this. i prefer the Olds 350 over the 455 due to a much lighter resiprocating assembly, far less failed builds. The problem was a 100 ci deficit to make up, the new 4 inch stroke in 5140 or 4340 billet steel is actually lighter than the 330 crank I am using and stronger. Of course I am doing a 424ci 403, so what do I know. Wish I would have waited to get the same ci from an Olds 350, consider it, blocks are near free and the stroker assembly for 5140 crank, aftermarket rods and forged pistons, rings and bearings is around $2500 US. Curious, what do have in this LS build, all said and done? I am not ******** on your thread, how does it feel compared to the 455? I also hate an immobile car, I put in a bent rod 350 just to keep my 70 driveable, cannot stand a vehicle sitting, so I get why an easy to find LS was used. Enjoy your car.
