350 Popping backfiring fire

[74 Shortbed]

Well dadgum! I guess Holley does make a lot of smaller CFM carbs too....so smaller jets would be needed for them like the 450 CFM 2-barrels and such. My assortments don't go that small but then I have jets for alcohol applications too which are huge!

They go smaller than that like a 390 4 barrel.
