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
Sounds like a lot of Carb for a 468.. Lots of different variations in my book. do you have a list #

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
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...
I'd put 6.5 power valves in it. If you want to drop the secondary PV that fine. I am not a huge fan of secondary PVs, but they can have their place in a road vehicle in certain cases.
If you use a secondary PV, I would start with 81 or 82 all around, if you drop the secondary PV, go with 81 or 82 In the pri's and 86s in the secondaries.
what do you think the vac. should be at,... and 32 degrees timing sound good?Quote:
