After building a full restomod, I have many unused parts for sale that range from OEM used to new in box aftermarket. I've been buying and selling parts for over 40 years so I'm not looking to waste your time or mine. If you're interested in something, please email me at "mtrunz@yahoo.com" with your name and "GTO Parts" in the subject line. This makes it possible for me to track and respond to requests. If any pics are missing below, I'll email whatever you need upon request. I would consider selling everything lock stock and barrel to one buyer for the right price. The list is long but here it is:

Pontiac 1966 421 XYH 4 bolt main block punched out approximately .030 to fit stock 428 pistons. Ram Air IV cam, Ram Air III heads and 1967 HO aftermarket stock cast headers. Block was hot tanked, and magged before engine and heads were professionally built. I have the parts to complete the top end assembly (valley pan, gaskets, billet distributor, coil, wires and gaskets including thicker RA IV valve cover gaskets) but haven't had the time to finish it. If I complete it, I’ll sell it for $10,000 but I'd let it go for $8,000 as it sits with all of the parts to finish it. I'll include the 4-barrel intake and carb that came off of a 1970 RA III GTO if still available but no price reduction if they are sold.
