What cam should I use on 318?

Summit K6901 would also work well for you too. Be sure to put new and upgraded valve springs on as well.

goldduster318,

I have a 1971 Dart Swinger. It has a 318, Edelbrock LD4B intake, Edelbrock 1406 600 cfm carburetor, A904, and a factory 3.23:1 sure-grip 8 3/4" rear end.

I'm thinking of adding:

Summit K6900 cam & lifters:

Summit timing chain and gears:

With the Summit cam and lifters, what valve springs should be used?

Thanks for your opinion/help!
