Re: Quadrajet 4MV too small?
This carb is from a 69 vette 350 CI 300 HP with automatic. This carb came with rather small jets from the factory, 67 main jets and 42 rods. Most Hipo combos used low 70s jets. A quick search of my records indicate the 455s use 71/72 jets with 43/45 rods. A properly set up Q-Jet will fed that beast of yours with no problems at all. Just make sure you get an accelerator pump that is ethanol safe or you'll get that dreaded of idle stumble after just a few miles.
