So, I'm wondering how many guys use their stock cranks over and turn them .010" or .020" or .030" on the rods and/or mains. Will I be safe?? Also, I'm assuming you can't "resize" the stock rods due to them being a cracked rod design. Is this correct?? So basically, if I were to turn my stock crank down and run some forged rods/pistons would I be ok to turn it 7k rpm's or more?? It would be balanced of course and built correctly. LOL


*Also, is there any disadvantage to re-using a '98 LS1 block?? Are they any different than later LS1 blocks?

**What are the power levels that stock crank/rods/pistons will sustain?? I had hear 1000rwhp on the crank and 600rwhp plus on the stock rods... true?


Thanks in advance!!

You can resize the stock rods. They sell oversize on the o.d. for the bearing. You have to hone the rod .001 to .002. Clevitie CB-1776- 10 20 30 undersize for crank. Turning your crank is not a bad idea. With ebay it makes it not worth while because you can pick a crank that is a pull out for a stroker that is standard and useable for less money than you can turn yours.

Thanks for the info... I wondered about oversize OD bearings and I've also looked at some used cranks on ebay.... shipping is expensive though
