I have a 1988 Chevy 1 ton dually with a TBI 454. I took out the bigblock and replaced it with a CARBURATED small block 350. Dual tanks, both have electric fuel pumps. I installed a fuel pressure regulator and took off and plated off the manual fuel pump. My problem is this....when I take off from a dead stop, it loads up. Down the highway, if I push down on the gas, it acts like its out of fuel....maybe again loading up, not sure. Wont idle when in gear with my foot on the brake. Ive chased my tail thinking its timing, reset the dist. etc. I used the dist. from the bigblock for fuel pump purposes. Im pretty sure its fuel. Its a standard bore engine with a mild cam and a quadrajet carb. Nothing special. Ive had the motor in other cars and it runs like a dream. Right now its junk. What is the best way to adjust this prob? The regulator has a return line, has a hex screw with a jam nut on top. I got it from autozone. Im getting fuel, lines are hooked up correctly. What is the best adjustment for this? HELP!
Thank you,

What's the fuel pressure at the carb?

The stock TBI distributor is not the right part for a non-computerized carb. You need one with vacuum and mechanical advance.
