Going LS2
Hi !
Currently running a C5-2K MN6 with 66cc AFR 205´s, comp cams 921 spring kit / push rods, yalla terra, G5X1, LG Pro, SLP oil pump, dual cam chain etc. On a standard LS1 manifold / LS1 throttel body(
). Instead of upgrading to a FAST 92 i decided to by an allmost NEW LS2-2007 complete engine to get some extra torq. Will move AFR´s, cam etc. to the LS2 block. Will end up with pretty much a new engine ! G5X1 will stay in because of SMOKE regulations that i probably will PASS with E85 gas and a special tune. Hoping for some real 430rwhp. I will probably at least port the LS2 throttel body.
Questions:
- will my standards length pushrods be ok (7.400) ?
- can i user LS2 oil pump with 67-7000 rpm max ? LS2 engine is rated for 6500.
- LS7 lifters ?
Any other ideas ? Need some advice from you guys if i need to order eome parts.

You can use all the parts you listed. I would check with a good cyl. head place, like TEA, to see if you need to rework your AFRs to work optimally with the 4" bore of the LS2. While you have it apart, and all...Not sure, but think the LS2 shortblock will give you more compression with your stock 66cc heads. Also, if you're using an '07 LS2, I think it's got the wrong reluctor to work without some kind of adapter.
