    Has anybody done a LS1/4l60E swap into their first gen yet? I'm considering a swap like this on my project 72. What do you guys think?

    That swap is gonna require alot of fabrication and will be very expensive. The motor mounts are all deifferent. I have no idea about oil pan clearence and wiring would probably be a pain. Unless you have your heart set on the LS1 I would try another fuel injected motor like and LT1 or L98.

    As far as I know... An LS1 is a different breed... You're stuck with either the 6 speed or 4L60 that comes behind the LS1... The Engine/Tranny won't bolt up to anything else like factory... The LS1 engine and trannys are different.
    I'd go with an built LT1 or a TPI engine since it will bolt up to anything you want like factory. TH400/TH350/TH700/SM465/NV4500 whatever.

    Yes they are different. I'm planning on using the 4L60E that comes with the engine. I believe advanced adapters makes an adapter to mate the 4L60E to a 205. I'm really digging the LS1 right now due to it's very light weight, high horsepower/torque, and fuel efficiency. Some of the Fbody guys I've been talking to have nothing but praise for the engine. Thanks for the info. I had initially planned to do the swap in a TJ but found a nice 72 that I couldn't pass up. We'll see how it goes.
