Come on not that old! I'm 55. My kids help me with Facebook.I talked to the guy today that built it for me. Yes it's rebuilt. Mild thumper cam, has a rump rump at idle. Roller rockers. He said I worry too much. Getting up to 220 not bad on a fresh rebuild. He said yes he wanted timing at 6 btdc. He works at our Napa machine shop and builds motors for his son that races local. He is 68 I think. Starts at turn of key easy. He said now if it heats up after together and down the road then I should worry.I have big electric fan pulling air through.
