What cam should I use on 318?

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!

You can use basically stock replacement 340 springs provided you don't have exhaust rotators (if the intake and exhaust retainers look the same, you're good). It would be the same with the K6901, not too different than a 340 HP engine.
