Got the sonic map today it looks like a 4.080 bore will work. While the stock bore was 4.050 the cylinders measured from 4.055 to 4.070 so it has wear. Most of the walls were at least .250 thick the thinnest was .166 so if need be we can bore at least .060 over. The plan is to bore to 4.080 and stop and check. If that bore doesn't clean it up we will reevaluate. By the way thanks for all your input on cams. Probably going with a hydraulic roller. Both comp cams and crane cams have good tutorials that help sort it all out.
Hey Barry, in your book you stated that you often use solid flat tappet in you 445 builds.
Are your builds more race oriented or has the hydraulic roller much more improved since 2010?
