Poll: LS3 or LS7 vs. GM Crate Ram Jet 502

[tyoneal]

LS7 or a LS3 with a Magnacharger. The first will get you to 500 hp, the second will get you there plus about 150 more.

If you have the cash...LS7 all the way.

Best of both worlds.....aluminum big block thats injected. Not a big fan of the LS series with fuel injection. Now when you put a bad ass hogans intake or carb on an LS7 I am game. I think you can do better than a 502 for the money. That is why I built my 489. More power and a nicer engine for around the same money.

LS engine I know we all think power , but with gas at 4.00 gal. Power and milage would be sweet!!

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 !
