[B]Shifting good.

I know when I'm building up speed, when it reaches third gear it seems like the power drops off, like it doesn't really want to go any faster.

When I am under the hood and revving the engine at the carb, it just seems like everything's perfect and sounds really smooth.

When I'm driving, though, it seems like a totally different engine.

The thing that stumps me is that I've changed out points distributors twice with new ones, then put the HEI in, replaced the carb twice with rebuilt ones from O'reilly's and nothing has changed!

That's why I'm wondering if there may be something internally wrong??

I dont think it's internal engine problems. if it were you would see excess smoke in the exhaust, or a rattle from lifters or valves and possibly have a mis.

if none of these are going on then it must be externally.
