New cam for my 318

Claude, with this equip[ment;

1) Edelbrock Performer dual plane aluminum intake
2) Edelbrock Performer 600 cfm carburetor
3) Mopar electronic ignition
4) dual exhaust - 2.25 inch, no cross-pipe, stock manifolds
And this axle ratio;
2.76:1
With stock sized tires, the RPM range of the cam I myself would use works well within the RPM range of the equipment and axle ratio up to 3.23.

I have used a 218/228 Crane and it worked well in a simlar set up. It could have used ethier more gear or stall. (I had a 3.21 gear.)
