Please Help Me..................
 

I want to build a 427 or bigger LS style aluminium motor, Carberator Motor/L 92 Heads/ PUMP GAS......Where can i buy a short block at good price? Is it possible to make 600 hpp on pump gas? thanks

The best way to do it will be to use a World Products block and LS7 heads. We have the first one released on the way to us for a project, we will be doing a build up feature and twin turbo it. We can build you a NA motor also.

You need to hang out at
 

www.ls1tech.com and all things will be known. Great site for the LSX motors.

If you are speaking of flywheel horse power your sites may be a little low. Those motors make tons of power. Steve Rupps motor made 573 hp and it was a heads and cam stock cube LS2.
