Poll: LS3 or LS7 vs. GM Crate Ram Jet 502 - Lateral-g Forums

markd · #1 05-28-2008, 07:01 PM

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?

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.

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.

Here is your best choice(s).

If this is too much, try these:

Turn key and ready to go LS3 engines.

These are the best I have found and they are not even Supercharged yet.

What do you think?

I've driven a 502 RamJet, I'd opt for the LS engine hands down. Toss-up between the LS3 and LS7; for the money of the LS7 you could have a modded LS2/3 that makes more power.

I think the LS7 is at the very high end of the budget, engine is 13k out of the box and I dont think that includes the ecm. Add the oil system hardware and electronics and you have to be at 15k, forget about forged internals, these engines go near 20k when done. To get an ls7 to 500 rear wheel hp gonna need a cam change as well(should be close). Im with Jody on the LS2/3 modded will be cheaper. Keep in mind the accessory drive systems for these engines aren't cheap and pipes as well. My vote is for the ls3 with a stroker crank.

Also has to be 100+ pound difference off the nose of the car comparing the LS to the ramjet.

I would look into the new Edelbrock/ Pat Musi EFI 555. Can be had for a little over 14k and looks to be a turn key setup. 675hp/650tq. Dart block, Scat forged steel crank, JE pistons, H-beam rods, Victor aluminum heads, pro flo xt fuel injection system, 2 year warranty, and they claim a little over 19 mpg.
