I need some help deciding what to do . . .
I own an '89 Hallet with the carb'd 454 mag and I want some more speed. I've been looking at exhaust systems, but they are not cheap and people seem to have mixed results with them. I am also considering the Stage I ProCharger. Any opinions on this?
Right now I'm running high 50s to low 60s with my 19 pitch 3-blade at 5500 rpm.
I'd like to see close to 70 if possible without breaking the bank.
Thanks,
Don
