15 on a stock motor, wow that is way more than I thought. I will take a look and see what he did. took a good look at the car and if I move that batt. to the trunk (wanted to do anyway) I can get a remote oil filter, go to and electric fuel pump, and run the pipe from the manifold under the front of the block, I should have room to run the exhaust between the starter and the frame rail, the pipe to the carb will be easy too. The motor that I have is pretty much brand new, there is NO sludge or nothing on the head, looks brand new under there!!!
