Issues with a rebuilt 360

Alright I’ll give that a try but there’s no way this could be a timing issue right? Cause I don’t think it is cause the distributor was right and I didn’t touch it but it does sound advanced as hell when the car is on

well, do you have a vacuum pod on your distributor?
if so, take the line off and plug it for now

see what that does

and then put some pictures up
show us what you got and let us know what carb that is
