Issues with a rebuilt 360

I just noticed you stated the cam is a MP 292 cam?

That’s a pretty big cam in a 360.
You will want a carb with 4 corner idle.
Nothing from Edelbrock would be on my list of recommendations for that combo.
Even the Speed Demon, which has 4 corner idle isn’t a good match for a cam that size(it’s listed for use with cams up to [email protected], and that cam is like [email protected]).

I’d be looking at a Holley Brawler 750.

As for the timing........ you’ll want to run plenty of initial timing.
20*......at least.

The issue will be, you’ll need to have the amount of advance within the distributor limited, so the total timing doesn’t go too high when you’re at 20-ish initial.

Depending on exactly what the distributor is, it’s either an easy adjustment....... or something requiring surgery.
I have an msd distributor intial timing is pretty easy but I’m not sure about the Total timing I was told it’s where your timing is when your at about 3000 rpms but what I don’t get is how do you adjust total timing without touching initial timing if your adjusting both through the distributor
