i have 1.7 on my car and i have no problem with hittin 5500 i do it very rarely. I have stock cam and springs. Id vote on either loosing spark or fuel.I also have the same problem when my alternator was goin it would hit 5k and spit and sputter and not go any higher.

my dad explained to me at wide open throttle you need more fuel so i have to bump the pressure up anyways ( im running lean)...i never bring the car up past like 3500 because i try to be nice to it and not race around like an idiot...( they take your car from you over here )

id definatly check fuel or spark, ur MSD may be goin never know.

PJC Racing

Yep you're right mjr46, I missed what heads he is running. Even with the stock Edelbrock single springs and that cam, there should be no float at that rpm.

id check either the msd maby u have a loose wire. Is that msd also adjustable???? but either way its fuel or spark

Pull the plugs and look at them. Any cracked insultaors? What's the gap? Any fouling?
