I saw one of our members post a craigslist ad for a 64 409 motor...it comes with a block, heads, rods, crank, pistons, and a camshaft...the owner was going to build the motor many years ago and has abandoned the project, it's been sitting protected for 10 years...all the parts are coded for a 340 hp 64 chevy...one thing that concerns me is that one of the press in stud bosses broke and was welded...is this a cause for concern...if I do buy it I certainly install screw in stud...he's asking 5200 but I'm sure he's flexible...any thoughts from the local gurus would be appreciated...
