Timing issue?

Re-reading the post here, '74, 318 guessing it is stock with a 4 bbl set up.

You are saying it is a new 600 cfm summit racing carb. What is the actual carb?

Do you have access to an Edlebrock 1406 600 cfm electric choke carb? Beg, borrow or steal from a friend or local car guy. Those carbs are pretty much fool proof, bolt on and go. No rejetting needed, run nice right out of the box. Just set the 2 idle mixture screws at the front of the carb and good to go. They just run nice . . .

They all have the 1406 Edelbrocks, they all run great. Simple, works well.
