Has anyone on here done this swap and if so what do i need as far as the radiator and trans x member. The motor is out of a 95 camaro and the trans is a 4l60. It currently has a 4.3 v6 in it.

The fueling system will be identical if you decide to go EFI.. Mounts will be the factor here with the LT1.

I used a LT1 Radiator & Fans..the Crossmember I used was the Jegs one for a 7004R/4L60E..I just adapted it for a T56.

My buddy did the swap with a 79 Monte Carlo and it was very easy. Stock G-body mounts and radiator w/ flexible hoses. He is running the double hump crossmember from Summit for the 4L60e.

I also believe gen 1 headers for the monte will bolt right on and clear. I helped install an Lt into a 85 and it was very easy and smooth.

He used a set of 1 5/8 headers when he was running iron heads from the b-body but when he swapped to the aluminum heads they leaked. He is now running 1 3/4 primaries and no issues. They are just regular G-body SBC headers. He posts on Gbodyforum. I am sure there is some info over there too.
