Got my Cuda together and fired up and can't seem to get to idle as good as I think it should. About 700 RPM in gear is it so I put a vacuum gauge on it and the best I can get it to pull is 8-9 inches of vacuum. Don't matter if it's in gear or neutral. I rebuilt the carb. cause it's been setting for 3 yrs. hoping to find a problem there but it really wasn't bad and didn't help much at all. Here's the rundown on the combo.
360+.030 Approx. 10.2 to 1 compression according to what KB says the pistons will be with the 68 cc heads but we didn't measure anything so that isn't verified. Note: the heads have also been shaved .020.
X heads with 5 angle valve job and minor porting and bowl relief. 2.02/1.60 Valves.
Cam is 226 deg.@ .050, 288 adv. dur., .450 lift, 72 deg. overlap, 108 LS.
Intake is an old Edelbrock Torker. Carb. is a 750 vac. sec. Holley.
Hooker 1-5/8 headers.
Mallory distributor and coil. Intial timing is 18 degrees. Total is 36 degrees.
I didn't think this cam should be so big that it wouldn't have any vacuum but what do you guys think? I degreed it in when I installed it and it came out about 1 degree advanced.
