383 needs more power

The thing about dyno's is they are a tuning tool. You could drive down the street to a different dyno and gain 50hp, or loose 20.

Was any tuning done to achieve your output?

Tell us more about your combo. What is the static timing and total timing at what RPM? What ignition system are you using? Have you looked at the plugs to see if you lean or rich? Was the engine rebuilt?

No tuning was done. I was hoping the tech would spend more time tuning on it but he told me he was too busy and unfortunately is the only local guy with a dyno. Next one is three hours away. Initially timing is 15 and up to 35. I have a MSD 6A ignition system with a MSD pro billet distributor. Engine was rebuilt in 2012 with all new bearings, pistons, rings and bored .040 over. Peak HP is 4450rpm and peak tq is at 3950rpm. A/F ratio was pretty good on the dyno. Just want a good hp street car. It currently has 4.10 gearing and I want to put in some better highway gears but don’t want to lose the cruising around town fun part either.
