So I've got a 97 SS that now looks like a mismatched LS1 SS. I'm running a craigslist LT1 that's bone stock, down to the mani's and Y pipe. The engine sat for years before I got it. I did a dry compression and leak down test and my numbers were all over the place. I took the chance that it just needed to be run. Long story short, it took a while but it started to run pretty good. So now I've done 3 track days and it and it blew me away. I fully expected to go home with no less than half of the Pistons I started the day with. Not only did it not miss a beat, it used at most 1/2 quart of oil, no smoke, and seemed happy as hell all day long.

So my plan was for an LS1 swap later this year. But now I'm thinking this engine might be healthier than I thought. TT3 rules require me to have around 350 rwhp for my comp weight (3400 lbs). I can knock 100 lbs off the nose by going to an LS1 and light flywheel and clutch. The problem I have is my LT1 isn't worth anything. $500? Maybe? I figure the LS1 swap will cost me at least $3k. But LT's, cam and tune will be about $1500. I figure both should get me close enough to 350 rwhp.

Right now I'm way down on power, so I have to do something. I really want an LS1, but is it worth an extra $1500? At the same time I'm afraid I'm going to buy headers and a cam and the next day it's going to blow up. What would you guys do?

LT1 engine parts are not real common these days. I fear you could have issues if the motor lets go and you need to find another one. On the other hand, you have the benefit of time so I'd look for inexpensive LS1 parts and start collecting things while you keep running the LT1. Hopefully, you can gather up the swap parts before the LT1 lets go. In good news, the LT1 version of the T56 seems to be increasing in value because they are getting a bit hard to find. I'd think you could sell your trans for more than an LSx trans and maybe make up a little bit of the money.
