hey all. was wondering somthin'...

I've got a mopar 360... its stock except for the intake is an Edelbrock performer with a rebuilt holly 750 on top and a pair of hooker headers. heres the thing. i have no idle problems, no WOT problems, and no part throttle problems. However! from idle, if I step on the gas pedal hard or just enough, the car bogs (like a cough, and some spit back through the carburetor may occur) ,but if i gradually give it gas i have no problems, i can rev as high as I want! i only have problems if i jump on the gas.

what could it be??? is the engine and intake/ carb set up the prob?

could it be timing? i put the #1 piston at TDC and checked the location of the rotor in the distributor and its position is all ways constant, but its not exactly lined up with the number one spark plug... its slightly off, what exactly does that mean?

thanks if you can help

I think it might be a little bit too much carb on a stock 360 Mopar. I run a 600 cfm Edelbrock on my stock 460 Ford which works great. I also live at 5000ft elevation, so less is better.

As to your last question, nothing. Phasing will never be exact. As to your first problem with the carb, the accel pump needs tuning or verification it's supply a complete shot of fuel.

it is supplying a complete shot of fuel so i guess ill play with adjusting the accelerator pump tomorrow. what would you say: adjust for more fuel to be shot in or adjust for less??
because it may be the case that too much fuel is being shot in and the engine chokes on it then recovers OR that too little is being shot in and coughs and then recovers. if the accelerator pump is the problem.

After you try more or less accelerator pump shots,verify how lose is your camshaft chain.It will give the exact same problem when too lose.

Usually not enough fuel
