Coil could be going south.
By Wayne K. - 11/11/2005 7:53:46 PM; IP 4.240.60.244

A coil can cause that, deteriorating to the point it wont rev much past 1500 or so (happened to me).

But it could be as simple as 38 year old valve springs. I'd be surprised if it WASN'T the valve springs if they are original.

Another thing that can hamper, but maybe not stall, acceleration is if a timing set is installed advanced, especially a high torque style cam. Advancing those really pumps up the really low RPM grunt but does very bad things to upper RPM power.

Yet another thing to check:
Fuel pressure can do strange things too. If the fuel pump / lines can't keep up, then of course the engine can have similar symtoms.

One last mention:
I knew a guy once (not me really!) who had a super small air cleaner (REALLY small). and it sat very low on the air horn of the carb so it would stop pulling at higher RPM. Imagine that.

Good luck,
Wayne
