Got a 4 bolt main cleveland. 1972 block, 1971 4 barrel open chamber heads 1970 doa -L intake. Runs great. Never overheated, Very good oil pressure. Complete long block with intake. I put the stud conversion kit in with harland sharp roller rockers. New mild crane cam with new lifters new timing chain, and ALL new Felpro gaskets, new auto flexplate, new water pump. I was at the dragstrip with it once this year and it ran a 13.51 in my tubbed car. I am now putting my 408 in this car and my other windsor back in the mach. I don't have any more storage space. $650 firm. (I have alot more than this actually in it) I do have a nice set of headers for it and a REAL nice set of M/T polished valve covers also but would have to ask another $100 for these. (Got alot of work in these). p.m or whatever. I can email pics of the motor when it was in the car if wanted.
