I have for sale a 1976 Cadillac 500 V8 engine and tranny..Engine has been torn down for performance rebuild. No work done to it, just torn down to bare block. Heads are the stock large 120cc? smog heads. Tranny is a TH400 with the long tailshaft i believe. This also has the Buick/Olds/Pontiac bellhousing pattern. Will not fit chevy motors without adapter. Still have most of the parts..no intake manifold and the exhaust manifolds were cracked. Never been bored and the car it came from had right around a 100k miles..Great performance potential...Offers considered...
(Phone # omitted - it is in the ad though)...
