De-Stroked aluminum 5.3

[Steve1968LS2]

As a possibility to power my Track Rat project...


I was Turn Key Engines building the 427 LS engine for the Project American Heros Camaro and saw they have PALLETS of 5.3 ALUMINUM blocks. Litterally dozens of them.

So we started chatting and decided it would be cool if we could come up with a budget minded high-reving 302ish displacement engine.

Would be super lightweight and to keep the cost down would use all GM stuff except maybe the pistons (since we would bore the block).
4.8 crank and rods then top it off with an LS6 intake. If we choose the cam right I'm thinking 500hp isn't out of the question.

I've been considering a 5.3 but hated the idea of the heavy iron block.

Thoughts?
