I have a completely rebuilt GMC 228 engine and a 3-speed transmission for sale. Engine runs great and the transmission shifts smooth. I am building a street rod, and this 6-cyl. does not have the ponies that I am looking for. I will take $500.00 for motor and tranny. If you have any questions, email me at phil@sageoilvac.com. I also have a complete 1978 Firebird subframe for sale. Thanks for your interest, Phil
