anybody know what V8's would fit instead of a L67?

Nope. Not a common thing for people to do, if ever.
Really no point, the L67 can make the power of a N/A V8 for less than the hassle/costs.

it is possible. there was a guy who did an LS1 in a GP on club gp

I wonder if his was RWD? I would like to learn more about all this...

Iirc the LS1 was a RWD conversion. I've also seen Northstars dropped in. But keep in mind a lightly modded L67 will out produce a Northstar. Plus there isn't much aftermarket go fast goodies either. I believe the 3.1L has more mod potential then the Northstar.

but a 3.1 and an L67 cant make the same great sound that a N* can. You could try the 5.3L that GM puts in the GP GXP.

I keep forgetting about that GXP.

Not sure what mods would need to be done to the engine compartment to drop that in. I do know it still uses the 65E-HD

You can drop in an LS4, if you can find a wrecked GXP. There is a transverse mounted LS1 in a Monte somewhere (seen pics), but it required a custom adapter to mount and work.

Your better off with the L67, honestly. There is a RWD GP with an L67 running 8s. The only thing you gain with the V8 is exhaust rumble.

Got a link to anything more about that? That's purely amazing..

It's a guy on Club GP (the thing is 100% gutted with 4-link rear and huge slicks), but it exists.

I'm faster than a lightly modded GXP.

So am I...

Apparently the GXP V8 will fit. Barely. Or so I hear. My references are quite knowledgeable. :]

My own personal opinion: L67 > V8

I've completely crossed over; I'd miss the supercharger whine. Besides, the L67 is perfectly capable of kicking a significant percentage of V8s out there to the curb.

me too...

The money and effort to transplant the GXP's LS4 into another GP wouldn't be worth it unless you really wanted the V8...

For the money you can mod the L67 to go a lot faster...

The 04+ GTPs and GXPs benefit big time from a PCM upgrade. Because of the use of the 4T65E-HD the programming is putting in some serious torque management to preserve the life of the tranny.

Ya I know the L67 has lots of potential we all do. The fact is somepeople want to be different.

When I had my 63 Nova I was going to hot rod the 250 straight six it had in it. Only because all the others were your standard 350/350. If the block wouldn't have been toast I woulda built it. But the block wasn't worth saving.

It's all well and good to be different; I'm an advocate for such, but it's only fair to let someone know when the way they want to go will be somewhat difficult and costly.

I think it would interesting to see a GXP engine in a 97-03. Someone else can work through the PITA process though, and most of us could still give it a run for it's money.

I almost did it, but backed off on account of the down time it'd have caused me along with the incompatibilities that would have had to be dealt with between the pcm and bcm...

I still think it'd have been one cool little drop in had I had the resources to do it... =D

i agree the L67 is def the best choice, i just like to see what u guys think. the N* is crap, my mom's had a few in her cadillac's. whenever my pop and i lined up, i'd blow the doors off it, but top end that motor will put up good a fight. they enhale gas though and i mean destroy.

I would love to do an LS1 with an M90 on it. i'm planing it out when this motor (if ever) shits out on me.

as of right now i have no reason to touch my GTX it beats most V8's with mods.

Whew, good luck. You'll have to get custom everything, and a lot of mods to handle the boost since LS1's are very high compression (for some reason I'm thinking they are 12:1). It'd be better to just buy a Procharger kit which is premade with all the components for it.

ive seen it done and oh boy it's sick nasty, only if u slap in intercooler to it.

there is a guy in florida that has a S/C LS1, he was at our local mod day. I didnt get to look at it, but i didnt even think it could be an M90 blower

yeah... V8's like centrifugal blowers. they're easier to adapt (mount the unit, get a belt around it somehow, and run steel tubing to the intake) than doing the entire upper intake custom. i've seen a roots type supercharger on a GTO that seemed pretty crazy (and expensive).

This will mate upto the LS1



power increases of 123 hp and 124 ft-lbs of torque for the LS2 and 110 hp and 120 ft-lbs of torque for the LS1.

price

$6,599.00

For that you could get a built tranny and a turbo setup for your 3800
