Probably fuel starvation

On the way back from the OMC picnic I noticed that on the freeway at 5500 rpm

I would lose power...as if i had a rev limiter. The engine runs and idles fine at all other times. Before I left for Los Angeles I put in some carb cleaner and all worked fine....even past 5500 rpm....but now something's changed.

Apparently I'm suffering from fuel starvation but I wanted to be sure of all the things to check....I'll probably start with the filter and then maybe get something that allows me to check fuel pressures. I have heard about that gas tank sock thing too. Plus maybe this is a good time to put in an electric fuel pump.

Any other things that might be causing this? Thanks,
Mike

Red coil

bosco said:
I'm beginning to think this is an ignition problem.....ie. possibly a weak coil. I am running a Crane 700 ignition system and wondered if anyone has used one of Crane's coils. In one of my Z-car catalogs they show Crane PS-20, PS-40, PS-60 and PS-91 coils. Has anyone used these or know about them. Currently I'm running an older Bosch red labeled coil.

Thanks.

What do you mean by "red labeled" . . . Bosch red (body color) coil with label that says it requires a 1.6Ω resistance in +12V side?

If so, hope you either kept the stock GT + coil wiring with the stock resistance wire or provided the required resistance for the coil in "run" mode.
