Hi, I am about to put a comp cams 280h in my '69 mach 1 390, it has 10:1 compression, an Edelbrock streetmaster intake, hooker headers, I bought the correct springs but the converter is only a 2000 stall. Should this cam be OK ? and is it necessary to use a degree wheel when installing or can I just align it to specs/. if anyone has the same cam in their 390 please let me know or any comments are appreciated. Thanks, Bill
