In the evning its fine- in the morning I start it, let it warm up and drive to work. Its only about 2 miles to work and all but the last street are 45 mph zones with stop lights that I mannage to hit every one red usually. My truck is fine untill the last street; its a 55 zone and when I let off the gas at the end the rpms drop and it dies. It starts right back up but its anoying. I havent got a clue what keeps happening but im thinking either the timing is off a bit or the carb is misadjusted? Its a 63' 327 rebuilt a couple months ago with a new holley 4160 and new dizzy hei with 1 gold and 1 black spring from a curve kit. I know its not a vac leak. Only vac lines are the one from the carb to the can on the dizzy and the power nreaks. Both are new and the brakebooster is new. Mannifold is edelbrock airgap and checked for leaks with propane- no leaks. And just to say this again; it drives fine till I have to stop after hitting high speeds. Thanks.
