[ERA427]

So I (with my ERA 427) am running a stock 428 Cobra Jet build with headers/pipes, and Holley 750. I’ve got a 3.54:1 rear, and a TKO 5-speed. I don’t take it to the track. It all runs great (starts right up, idles fine, good throttle response, never stalls, and sounds healthy at all rpms).

Now, I know most of you would say “don’t mess with it!”


But “if” I wanted more power, what do you all think would be the best place to start? Is there anything that wouldn’t come with a bunch of drawbacks?

1st and 2nd gear seem to have all the power I could put onto the pavement. 3rd is good, but 4th and 5th gears feel unimpressive. Or another way to say it is that 0-50mph is good enough but from 50 up, I wish it felt like it had more kick. No, I don't "need" the power for anything. I just want it to pull better at higher speeds without giving up on the low end.

I'd prefer to add power as opposed to change the rear gear.

I like the authentic-ness of my build so I’d prefer something that isn’t obvious upon quick inspection.

I’m not expecting any easy answers. But wondering if anyone has done any mods that didn’t come with a bunch of new problems. Is there a "single" upgrade that makes any sense?

For example, is there a different cam that is simply "all around better" and doesn't necessitate a all sorts of other mods to make it work well?
