Not Ranked
Duane,
I am going to think about this a few more days before I act. After bumping timing with no success, I believe the problem is a momentary lean condition or possibly a vac leak that could cause the same. There are certainly no leaks around the carb or on top of the intake. The bottom of the intake is tougher if not impossible to check.
I agree with you. After a hall way conversation today at work we determined and confirmed that 65 and 66 Ford 427 equipped cars had 850 double pumpers. The 750 is probably being stretched a bit for this application.
I bought the car with 800 miles and it has always had this stumble, so I have not cleaned the carb yet. I may do a complete strip and clean and change jets pure the Holley suggestion.
My other option is to go to a local engine tuner for an opinion.
I thought I had a line on a 800 cfm Holley for a test run but that petered out. It would be nice to try a 850 double pumper, but I am not confident enough to purchase one yet.
