Fuel delivery issue.

[veinbar]

I have a '79 SWB bonanza 2WD w/ 350ci/ TH400/ 3.08 12bolt rear. I have built to be a daily driver w/ only slight performance mods. A Sean Murphey Q-Jet delivers the fuel, but I feel that something isn't adjusted correctly.

When I "floor it" it doesn't take off. I can't even chirp the tires. It slowly builds power, but there's no launch. It's not sputtering, bogging, or anything, as a matter of fact it's pretty smooth, but it feels terribly weak. This is true on the highway or city streets as well. I hit the gas hard, and it makes more noise but doesn't really accelerate like every other sbc I've owned. The motor is new, new dual exhaust, new smi q-jet, etc... Any ideas?

I do not have a fuel regulator in line, but I'm using an OEM mech fuel pump.

Thank you in advance.
