I recently bought a Duster with a 73 360 motor,edelbrock intake, edelbrock csrb, headers, it was running really poor when i fired it up, turns out it had 30 degrees initial timing, so i backed it off to 16, stripped the edelbrock carb, cleaned, checked and replaced a few gaskets and it ran a lot better. When i put my vac gauge on it, it read around 8 inches vac ? Driving it, it feels soft down low untill it gets rolling, it's got a 7-1/4 axle that feels pretty high geared and it feels like a stock converter but i thought it would be more punchy so i did a comp test today. Engine was cold, accelerator fully open, dry then wet. Opinions please. 2 4 6 8 1 3 5 7 Dry 120 115 145 120 120 125 120 100 Wet 135 125 150 130 135 130 135 110

#7 rings/seal may be a bit more worn than the others. How wild is the cam? what springs are in the dist? what is the total now & what RPM does it max at? Lets figure out the low vac #

36 is a good ballpark total (initial+slots) & I'm assuming this is with the can plugged. 16 is OK for a stock cam.

Yes can plugged. I've been doing other stuff to the car and ideally should be finishing my 470 for my Dart but [censored] like this keeps getting in the way.

I was toying with the idea of advancing the cam because of the low comp and tall gears.

Cam is probably bigger than optimum.

Do you think advancing the cam might help Dwayne ? also what's your thoughts on the seven cylinder, i dont think it's cam wear but could it be a valve sticking ?

I'm going to flush the engine, put fresh oil and a filter on it first. Mick

No 7 was right under the header, so fairly hard to get the fitting on, anyway i thought i'll do that cylinder again today and got 110 dry, 120 wet ? I picked a fresh set of plugs up today.
