This has been discused before. The LT1 is a Hell of a motor, why switch. All you have to put in is a H/C combo and you will beat ANY LS1 that is stock or mildly modded. Most make about 400-420rwhp with a h/c combol. It would take a lot to get the LS1 there, and cost a lot more. The whole swap would be stupid IMHO. No doubt, the ls1 is a good motor, but ive driven both and everytime i drive mine i get a cargasim, unlike the ls1. The LT1 is way funner to drive around town in than the ls1, IMHO

ls1 k member with motor mounts, ls1 fuel lines, ls1 ecm, tranny (t56 or 4l60e) for ls1, wiring harness, all accesories, air intake, exhaust for ls1. some say there will be hood clearance issues, which can be taken care of with the ram air hood for birds or ultra z hood for camaros. dont know if the rear will have to be switched to make the abs work or not.

I have a LS1 dragger...I have cc306 Stock heads, headers, exhuast and intake...dynoed 353 RWHP and 343 RWT..the LS1 swap would cost way to much...I looked at it and by the time you switched everything you would have 1 BAD *** LT1

Don't forget you will need an LS1 type fuel pump since the LS1 doesn't use a return fuel line and pressure regulator.

A guy in the MTFBA used fuel rails off of a '97 Corvette when putting a LS1 in his '92 RS. They have a return line which would eliminate the need to swap to a returnless fuel setup.

I know one guy who has completed the swap in his '93 Z-28, and another who is in the middle of the swap wit his '94 TA. If you have decent access to parts, can do the work yourself, are in need of a rebuild, want a LS1, and don't mind forking over the change, I don't see why you shouldn't. In a way, I wish it had been something that I thought of when I spun a bearing a year ago.

Also, the '93 Z with an LS1 has an LT1 style air induction on it and everything tucks under the stock hood just fine. There's no reason things shouldn't be the same with my budddy's TA.

Well see i bought a 95 Z body and it has no motor or transmition and i was just really wondering what i should do. Go through all of that trouble for a LS1 or just do an LT4 and all I would have to do is re-program the comp right?

If your going to swap, go to the BMR Fab. web site. They are coming out with a new K frame to bolt in the 454-502, now that's worth doing !

It stands for heads/cam combination. Meaning ported stock heads or aftermarket heads and an aftermarket cam.
