well I think you guys have sold me on the swap! but I'm affraid it will take me a while to get all the parts together and make it happen. Maybe if the wife will let me take a small loan I could go out and start rounding it all up!

Man that is some bad news... I can't believe that I can't use my LT1 T-56. Its gonna take me a while to either sell my T-56 or save the money up for an LS1 T-56! Good thing I have a daily driver

Well I guess my problem is solved! I just found a 2001 Trans Am T-56 with decent miles on it for 1,600 
Not too shabby. My second purchase of many for the LS1 swap!

I was pondering a LS1/T56 swap. I've had my Racetronix P&P system for about a year. Would I need to change that with an LS1 swap? I was planning on H/C/I, that's the reason for the fuel pump upgrade.

I was at Berger Chevrolet a few days ago and asked what replacement engine they have for LT1's. I was told that there is a specific book that details the LT1 to LS1 swap since there really is NO direct replacement for the LT1. It's called the LS1 Engine Kit Installation Guide, GM part no. 88959384. Obviously I haven't looked at it but maybe it's a start.
btw any one get a parts cost estimation for all the crap required for the swap?

I have an Excel spreadsheet of mine right now and its lookin right around 6500 to 7K... But seeing as I sold my shortblock for 2500 and looking to sell my heads for 750-1000.... Its really not that bad.

As far as speartech doing your harness, I got in touch with them last year about doing the same harness for my 94 Z28, and they told me that they really weren't doing much with the LS1 harnesses anymore. If you want, I can forward you the email I got from them about modding the harness, provided I can find it.

this is what my sheet looks like.
Engine.....................................2000
LS1 T56...................................1600
LS1 Kmember..............................100
LS1 steering rack and shaft...........200
Aeromotive FPR and fittings...........250
LS7 Clutch and flywheel................500
LS1 Slave cylinder and pilot bearing.125
Headers......................................500
PCM and Wiring Harness.................650
Misc(alt bracket, and little things)....200
That sums up to about 6000 and then maybe 1000 in labor or so. Kinda pricey but not so bad after i sell my engine and trans.
