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!

For your level experience, I always suggest that you buy matched stuff. I like Edelbrock I would suggest the performer and cam or the RPM and cam, and 600 Edelbrock carb. Elc. Choke, good idle, vacuum, and dual plane with good torque and performance. The RPM might be a little large for your heads, but if you have 360 heads on it you can run them. Good luck.

Normally I call this reply good common sense except it isn't good advice since the Edelbrck Performer cam is ultra lame and there RPM cam is a bit overly aggressive for the current performance level sought.
The "Matches" package is a great gimmick from Edelbrock. Walk away from it.

This is a father-son project (I'm the father). The boy will be driving it around town this spring and summer, cruising and I hope to eventually get the wife in it for some longer trips. Looking for cool with a little performance uptick, nothing crazy. Want the classic hot rod rumble too but don't want it to be stalling out. But I'm not in for a stall converter. Don't know gear ratios but it's a small, stock rear-end, nothing special. Running 225/70R15 on the back.

Thanks for the help!

I'm glad you know where you want to go with this project. I'll have to agree that a cam like the Comp XE262H is right about what you want to use. Lunati's similar cam is also a very good one to consider.

That muscle car sound comes from the cams centerline and opening/closing point as well as rate of lift and ....... To make it simple, a cam on a 110C/L will have "That sound" your looking for.
An intake duration under [email protected] is what you want to keep the stock converter. I ran an old Crane Hyd. (216/228 @.050) on a 112 C/L with exhaust lift @ .480, no head work at all. Dead stock 318 heads from '79 & J heads.
