Hi all i am having a problem that i just can't figure out. First i had a 406 in the car and i could not get it to turn more than 5000 rpms, so i pulled that and put in a 355 still the same. Thought it was the fuel pump, bought a new Carter, have 8lbs of pressure, bought a new carb. What else should i be looking at to get the rpms up more, it is like i can't get out of my own way on the track. Thanks for any replies.

sorry about not giving all the details first. The only thing not changed is the Distributor and the tranny. Put deeper gears in and still the same. This site is great and i appreciate all the help that you all give. This is what makes the racing communtity better then any other out there.
Thanks all.

What ratio of gear you running - I have to agree with the masses - Sounds like a tall gear.

I am running a 583 on a big 1/2 mile, mostly everyone else is running a 543 or 567. I had a 543 in at the biggining of the year and it was still the same with the 543 and the 583

Check to be sure the module in your distributor is a "race" module, not a bone stock one. Stock ignition modules are worthless above 5,000...just a thought...

I second that!!

Module first, advance second, coil third and net voltage fourth (keep 12V battery charged between races, run an Alt. or buy a 16V battery)

definately module if running an HEI
a tip on timing, start at 36btdc, go up if you don't get enough r's. Watch how your plugs burn, if your clean burn area is under the arc of the negative terminal, your timing is too low, if it is past the arc(closer to the center electrode) then you are too far advanced. Just watch that fine line between advanced enough and disaster...

IVE GOT A DUI DISTRIBUTOR WITH THE TIMING CONTROL IN MY MODIFIED....WORKS GREAT!!!

IF THE NEW DISTIBUTOR DOESNT WORK YOU MIGHT LOOK AT THE BATTERY....I HAVE SEEN A BATTERY WITH A WEAK CELL PULL A MOTOR DOWN LIKE YOU DESCRIBED....BUT DEFINATLY LOOK INTO THE MODULE AND COIL....ALSO MIGHT LOOK AT HOW MUCH PLAY YOU HAVE IN THE UPPER BUSHING IN YOUR DISTRIBUTOR......

I have ran a DUI distributor for the past two years. It has worked well for me. My only problem with it was one of the springs on the advance broke. No biggie to fix though. Other than that it has been perfect.

Eight psi of fuel pressure is too much for any carburetor I know of. I can't speak for a Carter or Rochester but if you have a Holley then 6 psi is all you should have at idle. This will make a definite difference in throttle response and acceleration.

Hey Earl, will a Carter Super Speedway pump cause a Holley 4412 to load up at idle? I've had 2 different carbs give me grief with the same pump at idle, but both opened up and screamed at WOT. What gives?
