plug gap and timing

Ok I just finished rebuilding my 1970 350.

Could someone tell me what the plug gap and timing should be?

I think its .035 and 12 degrees

I have an MSD 6a ignition and pro billet distributor will this change the gap I need?

I'd rather ask stupid questions and get things right than to do it wrong.

Thanks!

.035 sounds like a good gap.

As far as timing goes, it depends on your compression ratio.

If it's pretty much stock, 12 is a good base, and in between 25 and 35 degrees total@3800 should be fine.

Not unless you have less compression, leaner mixtures, and higher coolant temperatures.
