360 timing

I wish I could say all was great.
I swapped out the carb for a brand new holley street demon with the composite bowl. No more boiling fuel when I shut it off. But I do not have it "dialed in" properly'
Not confident in my ability to "fix" the distributor, I've purchased the limiter plate, springs and book from FBO. I haven't installed them yet.
Street Demon 750 or the 625? I can give you some pointers on dialing in those Street Demons if you need to. They're almost like an updated Thermoquad. And stupidly simple and I've rebuilt a many Edelbrock Performer/Carter AFB. Except I think the old thermoquads were just a tad slight better once they're were tuned in. (The wonders of a 800cfm carb that even a meek 318 can run)
Anywho, the big thing is your altitude and tune with an AFR gauge for the best results you can get it in the ballpark with a vacuum gauge.
I had to tune mine at 4500 ft. So I had to lean it out.
