ls1 402? Hey is it possible to bore my sleeves to 4.00" and put a 4" stroker crank in it without re sleeving. Iam looking for a cheaper way to build my 402 that buying a ls2 block. I searched and couldnt find any info on a ls1 402 just ls2s. Any info will help thatnks.
4" bore The machine work alone to install the sleeves would cost more than a new LS2 block. The least expensive way to a 4" bore would be an iron block unless you can find a good used LS2 block.

Ive seen LS2 blocks go for a few hundred bucks used.
Do not try to bore the LS1 out any more than 3.91, the common bore for the LS1 is 3.905.

I think the C5R block is the only way to go w/ a bigger bore. IIRC, you can't punch the LS1 stock block. Too thin of sleeves.
LS2 can do it w/ a new rotating assembly, I'm pretty sure.

i might be getting a 6.0 iron block from a friend that is taking it out of his truck and parting out the truck. I didnt want to go with the iron block because i already have such a heavy car, but it looks like its time for some more weight reduction.
