Set your total timing to 34~. Then check you initial timing. Should be around 15~-16~. If it's not, you'll have to recurve the dist. according to Mallory's instructions.

Mallory distributors are shipped with 24o at the distributor. That means you want to set the initial at 10o to 12o with the timing light.

I would recommend getting the curve kit later and setting distributor degrees at 18o and initial at 16o all in by 2,500. It will make your car pull a lot harder than the stock distributor timing,

If it were me, I'd get a distributor that has a vacuum advance (if your street driving it). Mecanical advance distributors are good for track conditions, But having the vacuum drop out your timing when you least need it (high load-ect) makes a much better running motor (to say nothing of pinging, ect). You want to make SURE that you have no more than 38-42 total timing. This is a common mistake especially with people that use old HEI distributors ( I've found some that had over 70 degrees). You usually have to get a adjustable vacume advance unit, because thats where you have to limit the advance curve. Lighter cars benefit from lighter spring/weight combinations, while heavyer cars like slower curves. The vacuum line can either be on ported or full vacuum depending on what your motor likes (bigger cams usually like full vacuum).
