64 1/2 D Code Coupe,
This has been on the back burner for a couple of years since I rebuilt my motor partially due to it runs fine and I spent a year in Afghanistan a few months after the rebuild. I have a 64 1/2 D Code with the stock Autolite 1.08 4100 carb. I removed the originally cast iron intake and replaced it with a Edlebrock Performer 289 intake. At first I used the stock carb spacer but couldn't get the engine to idle properly and it hesitated from a start. I removed the spacer and set the carb on the intake without the spacer and the engine just seemed to come to life. I have excellent throttle response at all RPMs and I have plenty of torque. My engine isn't stock. When I rebuilt it I put a slightly larger .456 lift intake/exhaust Crane cam, and I have 1.94" intake valves on ported stock 289 heads, and flat top hyperthuretic Speed Pro pistons. Has anyone else experimented with the Edlebrock Performer intake and got it to work with the carb spacer any better than my attempt?
