Well its very impressive to see how well a stockish ls1 pairs in a S chassis. I actually hung out with the guys at all american a while back ago, they were cool people. I am in the process of building off a LQ9 block myself. I am about 85% leaning towards a LS2 rotating assembely, but part of me really wants to make a easier 500whp/500wtq that a 408 stroker can provide with a mild cam.

I am sure I can make 500whp with a LS2 rotating assembly but I would have to run a wilder cam and I wouldn't make as much tq as a stroker assembly (I am sure it would be plenty for the chassis I would be putting it in anyway).

As far as oil pumps go I am probably more than likely going to end up using a LS4 oil pump or a melling pump.

So far my virgin block (with main caps) is still crated up and I have bought the stuff I know I will end up using regardless, L92 heads will be on their way next week (along with LS7 lifters and pushrods). If you have any feedback it would be appreciated. Posted some pictures below (not trying to hijack your thread in any way).
