Timing issues
Here is the problem, I have a rebuilt 351w with the timing at 10 degrees before tdc. When I try to take off fast it bogs down until I let up on the pedal. And then when I shut it off it does that continious running thing and spits back through the carb. There is also lifter chatter when I increase rpm's but goes away when I back the timing down. I lined my timing marks up perfectly when installing the timing set. And I am almost certain I installed my disty correctly. I checked everywear for vac leaks- none! It is in a 70 f-100 with a pertronix ignitor system. When I cold start it, of course I pump the gas a couple of times but if it doesnt fire right off I have to crank on it for minute with out pumping the gas. Any suggestion to solve this driving question would be helpful.
Thanks Tony

Before you do that, try retarding your timing five degrees or so. The run-on and the "lifter chatter" (which is probably preignition,) suggest that it is just over advanced. The distributor may need to be recurved.
