bad problem..

ok my 1973 ford 302 just started this...it will rev up to about 3200rpm and then its like its starving for gas but its still going slowly and it pops really bad..like backfireing...i think its the fuel pump what do you all think...it runs fine all the way to 3200...

Ive checked spark plugs..timing..spark wires..disturbor looks good..??

Is it backfiring through the carb? That would sound like a timing issue, if it runs just fine and dandy till you start to wind it up, then is goes bad... check your advance, make sure your dist vac advance doesnt drop off.
By the way how is the weather? I am originally from Harrisonville,,,

How many miles are on it? Is the fuel filter plugged? Dont waste your money on a new distributor if you dont know for sure that theres something wrong with it.

Mine did that when the points went bad. Ran perfect until higher revving than would act like starving for gas.

Backfiring out the carb is a timing issue.


On another note:
Some people when they do major tune-up work don't put any lube on the distributor cam.. Not lubing this cam will cause the points block to wear down really quick and cause all sorts of ignition problems

If you decide to get a new distributor, consider our custom curved Duraspark Distributor built with our new Full Length Oil Impregnated Bronze Bushing. The full length bushing improves timing stability and spark scatter. If stock appearance is not an issue, take a look at our one piece D.U.I. Distributor. Whether you choose the Duraspark or the D.U.I., we curve each on a distributor machine based on your engine combination. Please see them at:

:http://www.performancedistributors.com/forddistributor.htm

Also, there is now an excellent installation article on the D.U.I. Distributor on the Ford-Trucks.com site at:
