Last few times I really step on it such accelerating from 60-100 kmh, the engine suddenly dies, so start pumping the gas and then suddenly the engine comes to life. Sounds like a fuel pump maybe?? I have a rebuilt 750 quadrejet on my 305. I rebuilt the 750 because I weas expecting to use it on my 454.

Could be overfuelling the engine too....750 CFM is quite a bit for a 305 inch motor....how rich do ya have it set for ?

Can you deactivate the 4 barrels this might help the problem:confused0006:

way too much fuel for that small of a motor dude i would recommend a 600cfm or a 650cfm quadrajet or edelbrock, whats ur timing set at?

I'll check the timing....

Q jets come in ONLY two sizes 750 and 800. It is not going to be an over fueling problem. I love all the no brain opinions people have.

loss of vacuum would be my guess or possibly accelerator pump isnt adjusted right
