Ok , Im going to throw some information out there, some relevent and some probably not so relevent , so that we can all get a better picture of what's going on.
I have a 351W stuffed into my fox. I have an edelbrock intake, with an edelbrock 1406 carb with an electric choke, and the msd 6al ignition box, with matching Msd distributor( doesnt have vacuum advance). This car is supplied fuel by an external fuel pump, pumping fuel through a -6an braided fuel line, to a holley fuel regulator, which i have set at about 5.5 psi to the carb. The carb is sitting on a 1 inch spacer.
The problem(s) i am having are that
1. It takes holding the gas pedal to the floor to start it, then i have to hold the gas pedal to about 2000 rpms for a couple minutes so that i can finally get it to idle. Once it comes to an idle, it will continue to idle just fine. I can even rev it up, and have no bogging down issues or anything. regulator stays at a good 5.5 psi.
2. When i start to drive , climing up 1st gear and into second it'll hesitate pretty bad to the point of stalling out if i dont ease up slowly.
3. I finally work my way up to cruising speed, everything seems fine, until i try to let off the gas to downshift, or sometimes let it into neutral to coast to a stop sign...it'll flat out stall on me...but it starts right back up. or while im cruising and i let off the gas a little bit it stalls, but i can start it up while coasting.
Im up for any suggestion.. I'm a computer tech by day, and a wannabe car guy by night..this is all new to me, so there is VERY easily a chance im missing something simple.
The timing is set the way MSD suggests with the base timing and the whole advanced timing (cant remember the degrees )
The carb was a refurbished carb i got online from "the carb guy" out of texas...and he says it's set to boltup and go.. which he seems to know his stuff so wont question that.
I have a fuel filter screen on the end of the pickup in the fuel tank, i have one before the fuel pump, and i have one just before the carb, so i think the fuel is pretty clean. I pulled off the top of the carb because i had to readjust my floats, i didnt always have the fuel regulator on it, so it was pumping way too much fuel and it bent the float out of adjustment. ( or so i think.) I did set them as to what edelbrock suggests.
whew this is long winded.
so guys what can i try? what can i look for? how can i go about troubleshooting this issue?
Thanks in advance ,
