C2 Corvette LS swap fitment notes

The motor mounts drop onto the frame mount perches already in the car and take 7/16 x 6-1/2 inch bolts. Use the large flat washers on both sides of the polyurethane bushings so they stay in place under load.
The kit and headers are made for the F-Body oil pan or the Cadillac CTS-V pan. The F-Body pan gives a bit more ground clearance but does not clear the factory power assist slave cylinder.
Plan on 1998-2002 F-Body accessories.
A low mount A/C compressor will not clear the frame. Running A/C takes a Kwik Performance top mount bracket.
The headers work with the T-56, 4L60E and 4L65E. The mid-length headers have ball and socket collectors and O2 bungs.
The crossmember bracket uses the rear two bolt holes for a T-56.
Some later transmission crossmembers lack the right mounting tabs and may need to be swapped for an earlier crossmember, which can mean welding.
Expect a new driveshaft length. The factory clutch Z-bar will not work with the kit.
Header fitting can require pulling the starter, a valve cover or spark plugs.

1963-1967 Corvette LS swap FAQ

Which oil pan works in a C2 Corvette LS swap?

The guide names two: the F-Body pan, which gives more ground clearance, and the Cadillac CTS-V pan. The F-Body pan does not clear the factory power assist slave cylinder.

Can I keep A/C in my 1963-1967 Corvette?

Yes, with a top mount compressor. The guide says a low mount compressor hits the frame, so it points to a Kwik Performance top mount bracket.

Which transmissions do the headers clear?

The guide lists the T-56, 4L60E and 4L65E for the headers.

Are the engine mounts the same as the C3 Corvette mounts?

The engine mount kit and the mid-length headers on this page are both named for 1963-1982 Corvettes.
