car weights 3300#s
18#s on pump gas and 25#s on race fuel also looking at a alky kit to repkace race gas. Car also has red armstrong double pumper fuel pump
What should it run on pump gas and on race fuel.
 
Hoping I can get in the 10s on pump. But low 10s on race gas would be satisfying.
 
I have a very similar combo,i went 11.70 on pump, no alky on 18#. Race trim went 10.81@124 on 116 @ about 28-30#. My 60' was crap 1.62 on M&H dragradials

Can you go 30#s of boost with 93 gas and alky or do you have to run race gas at that boost level ?
 
I've been to 30# w/93 and alky, but not on purpose. Running about 26# w/ boost creep.

I've run 30+psi with 91/alky but that's with my little TE44. You should be flowing a lot more with your hair dryer.
 
What do you think is the limiting factor of the combo?

Not sure abt the limit. Op asked what it shld run at specified boost levels and fuel. If car weighs 3500 with driver mid-low 10's if tuned properly shld be no problem. I wldnt use race gas as alky with a proper tune is good for up to 30psi single nozzle and 30+ dual. Converter cld be an issue if its not efficient enough...
 
It should be able to run low 11's to high 10's on 18 psi with those heads. Low 10's on kill. This is assuming the tune is right on, converter is working, etc.
