500 to the wheels or to the flywheel?
If you're wanting 500 to the wheels in an all motor 5.7/6.0 you are gonna have to go pretty aggressive with it and it won't be cheap at all.
I'm kinda puzzled as to why you want to get rid of the LT1 for an LS1? Did it **** out or something? Seems like alot of work and money for not alot of gain.
Hell if it was me I'd make the LT1 a 396 stroker and put a blower on it and wave to the N/A lsx cars while you walk them.
just a thought..

To the OP, you are going to have a fairly severe duty race oriented setup to make 500rwhp with a 5.3, with those goals it would be easier to go with bigger cubes and budget parts than smaller cubes and max effort expensive parts.

Where would you find an iron LS1 block?

I meant boring the 5.3 bore of 3.77992 Inches to a ls1 bore of 3.9 inches.
Not that they actually made a iron block ls1.
