LS1,LS2,LS6

[Graham]

Can some one in quite simple terms explain the differences between them. I thought they were all variations on the same theme. but i've seen quotes that an ls2 doesnt fit where a 1/6 will. then there is the subject of hybrids !!!

Briefly
LS1,6(5.7),LS2,L76,L92(6.0),LS7(7.0)all have the same external block dimensions and mounting points.
There are a few changes to front and rear covers, inlet manifolds,knock sensor positions,sumps etc,heads are all interchangable,but you'll need the right inlet manifold to suit.

See the other post - Oh you are All fit in same whole bar the 7 with the drysump setup. Or a problem on pulley design if you want AC - similar issues to the &'s dry sump issue.

mmmm, so basically choose the one that gives me the best bang per buck then...

a/c dont need that, pas thats for girls and if needed i'll use an electic column. i could even run the alternator off the prop. might even go electric for the water pump.. it would be for the racer anyway...

500 bhp has a nice ring to it... 2008 season probably..

500bhp is easy for all the above engines, even with big miles on them! simply get a nice set of ported heads, or even aftermarket ones, a nice camshaft and a LS1 edit (lets you tune like a standalone i think) or go for an aftermarket. with a set of headers you should easily see 500bhp!

oh and if you want more then you could always put a 100bhp shot of N2O ontop of that! and with the right tune the bottom end will take it!

thanks Chris.
