? are your numbers wheel numbers or flywheel numbers?

I would look real serious at the exhaust system for gains.

at the wheels. On a dynojet 248C.

So with the mods you have you are making bout 160HP at the flywheel..rough estimate. I would bet there is a fair amount left in the exhaust. Also your base timing is a little conservative. What was your fuel pressure?

I doubt there is much power to be had in changing timing at the distributor. It would be within the "noise" level of the dyno. Being able to change the fuel and timing at each point is where you really see gains that can be measured. If you get 1 whp from 17 deg as opposed to 15, I wouldn't even bother doing it. That's in my experience anyways. I'd be interested in hearing if anyone has seen any gains otherwise. Besides, after blowing 2 motors this season from detonation, we erred on the conservative side.

Stock fuel pressure regulators, 15 deg BTDC.

I agree, I think a lot is left in the exhaust. I&#39;m changing header to a custom built unit and going to try different exhaust setups. 2.5" and 3" will be experimented with.
