This 495ci Pontiac stroker V8 and TH400 automatic transmission were removed from a 1977 Pontiac Firebird Trans Am. The engine was recently rebuilt with new piston rings, valve seals, and a rear main seal, and features an Eagle rotating assembly, Howards camshaft, and Edelbrock Performer RPM intake and cylinder heads. A Quick Fuel Technologies four-barrel carburetor, alternator, flex plate, and exhaust headers are included.
