not tuning related but i know you guys can help me lol
2011 cadillac ctsv with the 6.2 lsa engine developed a bottom end knock over the weekend
can i drop in a NEW GM crankshaft with new standard size bearings and get away with not having it balanced? its a stock motor just trying to tear down and reassemble over a weekend minimize downtime and avoid machine shop. its a street car not a race build but does see 6200 rpm car made 550whp
any advice is appreciated thanks for reading
A new crank, correct for the application? Sure, the factory stuff is batch-balanced and all the parts are interchangeable. If it's the same part# as the original it's the same balance specs.
ya looking at just getting a new crank straight from GM as well as gm main and rod bearings to put it back together over a weekend and back in the car sucks when race season is almost here lol i have to hurryOriginally Posted by blindsquirrel
Make sure to get a new oil pump - preferably a reworked one. Forgot who makes the best, so research it... These are bad for the bypass plunger to stick and wipe out bearings at high rpms. As long as you haven't spun any bearings you "should" be OK
2010 Vette Stock Bottom LS3 - LS2 APS Twin Turbo Kit, Trick Flow Heads and Custom Cam - 12psi - 714rwhp and 820rwtq / 100hp Nitrous Shot starting at 3000 rpms - 948rwhp and 1044rwtq still on 93
2011 Vette Cam Only Internal Mod in stock LS3 -- YSI @ 18psi - 811rwhp on 93 / 926rwhp on E60 & 1008rwhp with a 50 shot of nitrous all through a 6L80

The LSA needs the melling 10355 if it has the piston squirters.
Ive heard of guys putting stock rods or pistons in a engine without balancing. But if anything changes i take the rotating assembly and have it balanced. They are never just right unless it all comes from the same engine.
OP, the Melling 10355 is basically the same as the stock V's oil pump the 10355HV is the 20% increase in volume and pressure. ive been considering it when i do my cam swap coming up here in the next few weeks...since im down there already.

Yep. Forgot about the HV.
Is this the engine that destroys the mains from a spun cam bearing?
