I sent the below to Comp Cams as I need to ID several cams I have... some out of box, a couple in Comp Cams boxes. They said it none matched anything of theirs, so, does any of you recognize these casting numbers (on the cam itself)? The only thing I can find is the casting number on Cam End; 1st Cam 3180-259 2nd Cam 3231-029 3rd Cam 3234-029 Other than installing them and measuring valve movement with a dial gauage, any other ways of determining lift? I know with a degree wheel I could fig duration, but I don't feel like installing/spinning all of these if I don't have to! Your informed help is appreciated... have a great week, Jesse _______________________________________________ AMC-list mailing list AMC-list@xxxxxxxxxxxx http://list.amc-list.com/listinfo.cgi/amc-list-amc-list.com
