I run a q-jet on my 440 rpm intake, works awsome

I have a early SB rpm intake(no airgap) on the shelf,I dont see it getting hogged out for a spredbore carb.
just under the machined carb flange the intake plenum swells out and a spred bore will cut thru the sides.
I post pics later if you want to see the early rpm intake.
my buddys rpm airgap is the same way at the carb flange and have the same hieght measurment.
it taller than my LD intake for sure.
IMHO,adaptor is the only way for spredbore to fit the rpm intake.
I run a SB & BB with q-jets and adaptors on each

of course I have a truck with a SS hemi scoop on the hood so no clearance problems for me.
