Swap my Holley spreadbore 650 for your good Q-jet for a 454.

Anyone got a good 454 Qudarajet that you'll swap for a rebuilt Holley spreadbore for a 350?

454 Quadrajet? I was pretty sure that all quadrajets flowed the same (750) with the exception of some truck models that flowed 800. Am I wrong?

I understand they flow up to 850. But the point is that different Q-jets are set up for different engines; a 350 Q-jet won't do a good job on your 429 Ford cammer. I want one set up for a 454 so I doubt have to spend endless hours setting it up or endless dollars getting someone else to!

Right...well...all used by Chevy were 750 (some Ponitacs had 830cfm) but the differences were internal. Each was set up for a specific engine and power train. If you rebuild one you can change it over to another configeration, just need to know which jets, power pistons, and rods to use.

Vette-less for now
John,

I may have a brand new Q-Jet in a box in the garage that I'll swap with you. I'm on travel until Friday so I won't be able to check until then. Stay tuned.
