Default Need A Good Shop 4 Conversion

I am in Florida, but I'm looking for any shop on the east coast that can do an LT1 to LSX swap for me. Preferably a shop that has done the swap a few times. Can anyone help me out. Any and all locale on the EAST coast is welcome :-)... maybe a little out west, but not too far.

Lightbulb 96ImpSS...

I have a problem with this. I can't see a nice '96 Impala SS, (a future, if not current collectible) being altered this much for so little gain. I am a '95 Impala SS owner, also in southeast Florida & just could'nt justify the $15,000(or whatever) transplant, for slightly more stock engine power. There was someone at Tower Shops(corner of University & 595) about four years ago that did this swap & gained very little. I CAN see putting much less money into a ProCharger, blower or turbo set-up, etc., that would pay off in much bigger gains & that could be removed at a later date. Just my .02... Gar

I kinda agree it's not like most of us who are trying to get rid of 4/6 cylinder motors. There is alot of stuff that you can do with that car. But if you want someone I know a guy here in Tampa. Just pm me.

True.. there is alot you can do with that car and an LT1. But, if you want to go natural aspirated then there aint a hell of alot you can do with an LT1 and still keep it streetable. I have investigated several options, and I think the best and safest you can do with an LT1 is 383 or 396.. with that said, with a streetable setup, the best HP numbers you can get "NA" is somewhere around low 400 HP at the rear wheels. I am looking for about 540hp at the rear or maybe even 600 HP

The LSX engines have alot more potential

WARHAWK LSX WARHAWK LS7 HEADS


OR EVEN THIS:

ERL SUPER DECK WITH LS7 HEADS

or what about this:

GMPP LSX BLOCK with Worlds LS7 heads or wait to see what GMPP will make to go with its block.

I have a 95 Impala as well and I have been considering doing the lsx swap as well. You can't really compare the LT1 and LSx power wise NA. Not to mention, all the turbo and supercharger kits have unheard of delays and problems. I was considering keeping the LT1 and getting the Mease Performance Eaton blower kit but it never got produced in large numbers. Paxton doesn't make their blower kit for the Impala anymore and your only option is Combination Motorsports ATI kit which is very expensive for a blower that isn't well fitted to a heavy Impala.
I say go with it. There is a guy on the Impala forums that put an LQ9 in a 4.3 Liter 95 Caprice. His screen name was 2blue or something like that. There is also another guy that did the conversion years ago with an ls1 and six speed. NA he was running in the 12's. That is very impressive for an Impala SS. Most are happy to run in the 13's with a ton of bolt ons.
It really does not look that hard based on the research I have done and you have all the big displacement potential you would ever need with all the new LSx blocks coming out.

Good luck

I allways thought that was a 4.3L V8 they used them in City of Miami police cars. I remember they were V8's and 4.3L.

That's classic. Here is some good information reguarding the 4.3 you where kind of talking about http://www.automotiverebuilder.com/ar/ar99928.htm

The LS1 4L60E is not hard to do. I have a buddy that does conversions in FL, he does mostly S-10's but also does others. If your interested pm me and I'll pass his info along.

Boy,

I'll bet my cars would give you a heart attack then! I put LSX engines and late model drivetrains under incredibly collectible old Corvettes. It is all about what floats you boat, and other people's views really should have little to do with it!

Great Replies!... Doing a 383 or a 396 LT1 would probably be the easiest thing to do... but for serious NA power definitely there are more options with LSX engines.

The 500cid LSX from GMPP...jeez Now thats a stump puller!

I try to keep as many cars as possible, but sometimes I just run out of room!
A man can never have to many hotrods. For me, it is more about the project than the owning. I love driving these cars, but I am no sooner finished with one project, before I am looking for the next one!

The truth is, that I never cut up a good restorable car to do these projects. I always look for deleric hulks to produce these cars from. I also build NCRS restoration cars, and could never bring myself to butcher a restorable car.
You probably noticed on the pics of the 65, that almost every single body panel on the car was replaced other than the doors and body tub. This car had been given a 70's customization with flares on all corners, glassed-up headlights, and camaro tail lights. I try to end up with a car that looks as close to original as possible.

According to the guys at the GM booth at the recent SEMA show, an all new 454 cu. in. motor is about to be available, very soon. It will have newly designed heads, all designed after the great LS1 based heads/engine. And yes, blocks will be available in March 2007. Gar
