Stop in for a cup of coffee

The guy that has this one for sale should have some receipts. His threads started when he bough the short block I believe and checked it out. +030 flat tops in the short block. (unknown) #596 heads which are hardened seats. Windage tray, Melling pump, new cam bearings, New ghain and gears, Summit 6901 cam and lifters. (218/228 @ .050 276/288 .441/.441 114°) Milidon 5 qt. pan. Edelbrock Performer RPM, ATI neutral balance flex plate. I did the math. If all true, $800 worth of goodies. Sounds too good to be true.
