• The Monte Carlo tank listing covers the 1978-1988 Monte Carlo, 1978-1983 Malibu and 1978-1987 Grand Prix.
• Every G-Body tank here carries the 400 LPH pump, which BRP lists for supercharged engines or builds over 550 hp.
• Fuel line kit 6605-00 is made for the 400 LPH tanks and returnless fuel rails, and its adjustable regulator has a vacuum and boost port.
• The G-Body radiators are the same part numbers sold for the 1970-1981 Camaro, in bare aluminum or black epoxy.
• The adapters let an 8L90E, 10L90E or 2009-2014 CTS-V 6L90E tailshaft sit on a traditional mount on BRP crossmembers.
• The mid-length header listing is named for 1978-1987 G-Body cars.

Fitment comes from each product listing. BRP has not posted a G-Body LT install guide, so tunnel, oil pan clearance and transmission fit are not covered on this page.
