This here is a 1971 ford 351 Cleveland 4v block with 2v heads put on it. I bought it this way and realized it after I bought it. The casting number proves it is a 4v block with 2-bolt main caps. The motor was rebuilt 22,000 miles ago, (I bought it from an engine builder who gave me this info). Has edelbrock 4 barrel carb, shorty headers, brand new exhaust header gaskets, and popped off a valve cover and it is definitely clean! Also I have a top loader 3-speed with a hurst floor shifter and a starter for it. Motor is not locked up as I still turn it over by hand twice a month. Come and get a rare but cool hot rod and street friendly powerful engine. Make me a reasonable offer.
