I got a 468, turbo 400 , 308 gear 12 bolt in a 72 short bed cheyene..

the carb is a 850 vac. secondary carb..6.5 power valves

the motor is a cam'd street motor

what jets would you start out with....

the new holley jets aren't the drill size

so with the new jets what would you think

it has the rpm air gap,... I went on line and holley recommends this carb for my motor

the carb has had some guru's in it so I want ed to get a base ...

holley sent it out with pri jets ...78 (part # not drill) and 82 sec... also the power valves are 4.5 pri....3.5 sec..


I know you like to pull the sec power valve and I will probley do that next go round

That's what the book says it should have...

correct..

also when we were messing with the afr meter the alt belt had came off,... the voltage was down, so I think it was screwing up the reading...

anyway the better the meter read the worse it ran,,with 77 &78 jets I lean pop all the way home...
