My 66 went in to my shop a couple of months ago after i bent a pushrod and broke a spring. Luckily the shop said i didnt do any other damage. Symptoms when it happened started with a slight miss at hyway speed which got progressively worse. By the time i limped it home it was barely running.
Shop installed new valvetrain, pushrods, rockers and springs, reset the timing and adjusted the choke. I now have a problem where occasionaly, when im getting on the gas aggresively from a stand still, the motor just falls on its face, usually in third gear as im pulling past 3800. The car just winds down where sometimes it recovers and other times it stalls out after it scrubs off speed. The throttle doesnt respond at all when it acts up. If it does stall, it starts up again usually with no problem. Its kind of hard to replicate as it comes and goes.
I would like some ideas on where to isolate the problem. I dont know if its related to new valvetrain components, fuel system or ignition system. On a side note, the choke doesnt seem to work at all now ever since the shop i used tinkered with it.
