LT1 to LS1 Swap Dyno
So I finally finished my LT1 to LS1 swap and here are the results of the "new" motor post dynotune.
These seem to be fairly average numbers for a full bolt on LS1 with LS6 intake manifold. The old 355 LT1 put down 393 rwhp... but that was with H/C/I full bolt on! This is only the beginning with the LS1. Mod specifics are in my sig... More to come, just wanted to get some people's thoughts on the numbers!

Thanks! After spending thousands of dollars (and about a year of my life) unsuccessfully diagnosing a high rpm miss.... I decided I was officially DONE with the LT1 and it's optispark and decided to join the LS family. The car is in the 2800 pound range as well, so it catches a lot of people by surprise when they pick a fight

Same as you... couldn't find any single source (besides this forum), so I pieced together info and also ended up relying on a local shop. I went with Speartech for the wiring harness, purchased a used LS1 K-member from another member on this forum, same with the LS1 T-56 (you can't reuse your current M6) and steering knuckle. The stock hood won't fit a MAF setup so you have to either go speed density like I did, or purchase an aftermarket hood that provides clearance. I went with an LS7 clutch/kit... I think that's about it as far as "gotchas" with the swap. Oh and I had to procure an OBD-II PCM as my 95 was an OBD-I. Not sure if you will have to or not since you are already OBD-II.

Thank you for the tips! I'm thinking about a BMR or some other aftermarket K-member, just for the weight savings and stiffness factor, and was thinking about doing the front end conversion on my car, for either the WSQ or one of those ZR1 type hoods. And sadly, I'm aware of the T56 issue, there's guys around where I live who'll rebuild them with LS input shafts and bellhousings or whatever do-dads you need, but I'm thinking I may just trade mine for a built one.
