LS7 if you want 500 hp out of the box. If you want to build a motor an LS2 or 3 would be a great choice also. LS motors are moocho goodo IMO.

Don't forget to forge the internals on that LS7.......

The currect (today's) price of the LS-3 "long block" is $4600 USD. (with core charge)

Then add my coil kit, ECU-882C-1 (including software), wiring harness, the items (special for those here) $1995.00.
The GM water pump, ALT, GMPP "spider", injectors, my air door, costs are about $1000.00.

There are "small items" missing about $400.00

The result is a running engine with 500 HP.

Then add a cam for a 50HP increase ? (246/252 .580" 116)

That's a bargin, all new !

It also depends on if you want the look of a modern motor, i do not so i did not go with a LS motor. I will say now that you can get a carb for one and you can do some other things that make them look less "new tech" so they are not as bad now in my book.
