Does my 451 have to small of a cam?

Roger Price said

Ok guys, I got the cam out and I think I've been had! The gear drive has 3 marks on it and 1 on the cam. The one on the cam was lined up with the mark right of center. Also there is a # stamped into the cam between the lobs 292. Isn't that the cam size? And between the carb and intake is a thick plate with 4 holes way smaller than the prim./secd. On the carb! What's up with that?

Sounds like your timing chain is the type with advance and retard options. They may have installed it advanced or retarded. Hard to guess which since I don't have the timing set to look at. If you could post a picture of it maybe we can tell more.

If the spacer holes were smaller than the carb. holes it definitely isn't right. Sounds like that spacer was made for a small carb. such as a 600 cfm. So many times guys don't pay attention to what their installing. You need to get rid of that thing as it is restricting you.

The 292 stamp on the cam may mean something and maybe not. Look on the back end of the cam and see if anything there is stamped that'll identify it.
