Lsx cyl heads
Lsx cyl heads Ok I decided to go with a Lsx motor again in my street rod project,here's my thoughts.
6.0 block
bore 4.040
4.125 stroke
should make a 420
250/258 @.50 640 lift,might go a little smaller.
what I am wondering about is heads,go 6.0's ported,Ls6 ported,AFR's.What works best.

It will be a n/a set-up put with a little nitrous for fun.I don't really want to build a nitrous supported engine,it wont be raced,just a very bad street motor.
I have looked at AFR's,ported 6.0's,will Ls7 heads fit a 6.0 block.I haven't played with these Lsx engines that much so this is a new challenge.

The 2.20 valved original GM Corvette ZO6 427 Ls7 heads fit 4.100 '' bore and up Lsx's . It will take larger sleeves to fit these
ETP makes a small bore Ls7 head 250cc 2.125'' int 1.600'' exh valves to fit 4.000'' bores
They are a little stepper in price than standard Lsx heads but your are able to use the superior Ls7 composite intake manifold -also the best composite manifold made to date ,but can only be run if you use ls7 style heads and its under $500 complete .
The ls7 heads are more by them selfs but the intakes cheaper than a fast90 so its around the same $,$$$.
