Intake Fitment

Sounds like the choke is staying closed too much once started.

So the choke doesnt stay on that long. I have it sent towards the middle on the lean side of the pull off setting. I can try to see if loosening it up more would help.

Did you get the intake machined to match your decked block and shaved heads?

To my knowledge, no. I dont believe the intake went to the machine shop.

Most machine shops have a tool to check what the angle of the intake should be cut at. You will need to get the intake fitted before you go any farther. This probably was not done before installing the intake.

Take starting fluid and give small squirts around the parting line at the intake and head. also around the base of the carb. If the engine raises in RPM's this will locate a vacuum leak if any. The better way is a smoke machine tester . If you cannot drive the car to a shop with one use the starting fluid. Be careful not to spray to much at once if there is any spark you will start a fire.

I tried something similar with MAP gas. But I guess starting fluid would probably be best. I will also give this a try.

^^Or even just a spray bottle and water mist will upset the idle if leaking

There are so many other things. Cam timing, distributor curve and initial timing, as well as several things to do
I can try with water as well.

Your main problem is not enough timing at idle.......because of the cam. That cam will need 25-35* at idle. Easily achieved by using an adj vac unit connected to manifold vacuum. You start with this........

I tried increasing the timing and the car did not like it. I would get pinging at part throttle. Anything more than 14 degrees at idle and I have to close the throttle blades so much so the screw does not touch its stop in order to keep the rpms between 500-700.
