LS3 crate motor info

For all those who wondered or just want to get rid of that lack luster LS2(just kidding) GM will be offering the LS3 as a crate motor sometime in Nov. They will include a more aggressive cam, producing 485HP for EFI and 500HP carburated. So long,expensive LS7s......these are gonna be well under $9K complete from what I understand.

$9k But tell me how that would be better than a Kenne Bell Supercharger and 550+rwhp?? there due out in Oct.....Or a Maggie w/headers, cust tune, smaller pulley, 7psi 550+ rwhp too or Centrifugal P1 or D1s & 700+rwhp

Or head/cam installed out the door 480 rwhp for $4500?? I've got quotes from 4 diff tuners add headers $2k more 500rwhp

I appreciate what you're doing but just asking for the price the LS2 is no slouch when modded

Just passing along info, not trying to promote. I think it does show that GM may be sending the LS7 on it's way out the door in the near future soon.

I TOTALLY AGREE with C6Rluvur..... Let's not forget that the LS7 bore creates thinner piston walls than the LS2 so it is more difficult and risky to mod these engines and put the same kind of boost into them (as you can with an LS2). I have reached the upper limits with my LS2 and so rather than switch to an LS3 or and LS7, I'm going whole hog with an LS7X Warhwawk block.

Considering that the LS6 (405 hp)crate motor is available for around 4700 dollars (with some distributor discounts) will the ls3 be available at a similiar price down the road?

I think with a nice set of longtubes and an air filter the motor should put out a warrantied 460hp.

Thats pretty cool for those that like the reliability of a stock GM crate motor.

If I ever needed a motor in my c5 Z06 I'd go that route if it could work without tearing apart the motor (reluctor wheel issue)

Doubt I'd ever need it but it sure is a nice way to go if and when it becomes possible.

Well under 9k is well under trade in difference on an '08. Not a bad deal if you ever needed a new motor.

Wonder if there would be any computer issues being used to replace a LS1 ??
