1977-1990 Caprice and Impala LT fitment notes

LTX21 lists the 1977-1990 Chevy Caprice and Impala as its fitment.
Mounts with frame brackets, the Sure-Fit crossmember and the mid-length headers are each sold separately for the 1977-1990 B-Body.
There is no complete EFI tank for these cars here. The Phantom kit fits a pump and baffle into your existing or original style tank.
The 400 LPH line kit runs from tank to rail and is meant for returnless fuel rails.
The radiators are named for the 1970-1981 Camaro and 1978-1988 G-Body, and their listing text adds the 1977-1990 B-Body.
Radiator choices are automatic or manual, bare or black epoxy, with or without dual fans.
BRP makes the T-56 and TR-6060 adapters from laser cut 3/16 steel, powder coated black, with hardware.

Fitment comes from the BRP product listings. No 1977-1990 B-Body LT install guide is posted, so tunnel, oil pan and accessory clearance are not covered on this page.

1977-1990 B-Body LT swap FAQ

Does the LTX21 kit fit both the Caprice and the Impala?

Yes. Its fit list names the 1977-1990 Chevy Caprice and Impala. It does not split them by body style, so confirm your car in the LT swap kit builder.

Can I buy the crossmember or mounts by themselves?

Yes. The 1977-1990 B-Body Sure-Fit Crossmember and the B-Body LT engine mounts with frame brackets are listed on their own.

Do I need a new fuel tank for the LT?

Not with the Phantom 340 kit, which adds a pump, hanger and baffle to your existing or original style tank. A drill guide is included.

Is there a 1977-1990 B-Body LT install guide?

Not yet. The B-Body LT guide BRP has posted is for the 1994-1996 cars, and its 1977-1990 guide is for the LS swap.
