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

Just when I think I know how I building my car (69 Camaro), I read another thread on this forum and change my mind!

When I started this build, I was pretty sure I wanted a big block 502. I have only ever owned small blocks and was always envious of the power and rumble from an old school big block. I have been reading a lot lately about the LS engines and I am starting to waffle on my initial decision.

I live about 3 miles from Maple Grove Raceway and about 1 ½ hours from Carlisle Fair grounds. I will spend most of my time driving on the highway to and from shows, but will also take the car to Maple Grove a few times a year.

I want an engine that is reliable, bullet proof, awesome performance, neck breaking torque, great looks and around 500hp. I also want an engine that will add value to the build.

So my dilemma is this; should I go with the GM Crate Ram Jet 502 or a LS3 or LS7?

no..

the real question is WHAT IS YOUR BUDGET!

Okay, you caught me…I forgot the budget! $10-15k for the engine

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.:D 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.......

Jeff Schwartz? Where are you? LOL!

Ls-3
 

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 !
