69 L36 cam phasing question.

[Greg L.]

Is there a prefered set-up as far as advancing or retarding a stock cam in a stock L36?

I have an old bushing kit that will let me install the cam gear from 0-8 deg and was wondering if this engine could benefit from a few degrees advanced or retarded...or should I just install it at zero?

Re: 69 L36 cam phasing question.

The OE indexing POMLs are 110/120, which is considered "advanced". If you want to trade a little low end torque for top end power you can retard it 4-5 degrees, and this will work especially well if you massage the heads.

The same philosophy works very well with a base 327/300.

Thanks Duke.

If I retard it 4 degrees will it still idle like it would if it was set to 0 degrees? I'm thinking that down the road I might want to go for a PV award and I'm wondering if this retarded setting would be picked up on?

There will be no significant impact on idle characteristics - okay for a PV.

Overlap is the primary factor that determines idle characterisitcs. Within reasonable limits, how the overlap is phased has no noticeable effect.
