I boughta block off ebay....Cam was welded to the block from overheat.....sent to Boomer, who sent it to proline to get the cam line bored, and have cam bearings installed. The reason for this (i guess) was twofold.....ONE....I dont waste the block..TWO...one would be able to reap the benefits of having cam bearings so when we hammer it with 1200hp it doesnt go BOOM .....he was gonna use it for his personal vehicle I think...SOOOOOOOO... he recommended using this block since A-....we alrredy have it....and B- it would be better anyways. Costs about 2 g's to do the cam bearing deal, but the block is free at this point since it was considered Dead money anyways.....
