How to set timing

I have a 71 lincoln 466 with a mild cam, I was told the timing needs to be advanced 33+ degrees. Now, I've never used a timing light, how do I get it to the right timing

Well - this could be complicated.

Do you have a dial back timing light?
Do you have a timing tape or degreed harmonic balancer?
Do you know how much mechanical advance your distributor has?

Typically you set initial (at idle) at 10 - 14 degrees for mild performance builds.

The timing marks are on the damper, I have a mallory distributor (if that helps) and the timing light is is a "make waves" cheapy

MOST dampers only have marks for 15* to 20*. If yours has marks all the way up to 40* then you mark the line at the timing you want (33+). Next you start the engine and rev it up till the marks stop moving - probably around 3,000 RPM and see what you got.

Most cheapy timing lights are not dial-back types.
Most dampers (stock and aftermarket) do not have degrees marked to 40*. That is why Mr. Gasket (and others) make timing tapes to attach to your stock damper.

ahh ha, timing tape, see, that's what was confusing me, I was wondering how I was going to get 33 degrees. What dictates how far you should advance the timing? The cam?

Well - that question is getting a lot deeper.

There are two components of advance
Initial - what you typically set with the light
Mechanical - which is what is designed into your distributor. Since you have an aftermarket distributor you MAY be able to adjust the mechanical part with a bushing / spacer.

The combination of initial and mechanical give you total.

Now to the question of how much total timing you need depends on the combustion chamber design, piston type (dome or dish), quench and spark plug location. So with stock OEM iron heads and dish pistons it seems most people find that somewhere around 36 degrees a good place to be. If you have good aftermarkte heads (improved combustion chamber and sparkplug location) then you can use less lead time (less total advance). On my wagon, I am runing 30 degrees total (20 initial and 10 mechanical) but I have A429 heads with a small dish and 514 CI.

EVERY engine is different. To get the best results you have to test your combination to figure out what IT likes best.

That's where it's going to get tricky for me, I guess I'll just set it at 36 and go from there.

If you have a Mallory distributor you should have got a red plastic 'key' that you can use to pre-set the total ign. advance in the dist.

A long way from anywhere

I bought it used on ebay, I never got the key, I didn't even know of such a thing actually.
