Hi all!

I have in my possesion a setup of sixpak Holley 2300 carbs from a 427 engine. The list numbers on the outer carbs is 3659 and the center has 4782. The center is not original but probably an exchange carb, dont know.

My question is what the difference is to mopars sixpak carbs? I checked holleys pdf document and found that the CFM value is almost the same.
Will my carbs fit on a mopar sixpak intake?

Another question, is it possible to mount att 440" sixpak intake on an 400" block ? In other words , build an sixpak engine of a 400 block ?

Cheers

As long as the outer two (or just the rear carb actually) have a metering plate instead of a metering block then they will physically mount on the intake. Don't know if the correct carb lines and brakets etc will bolt up or not though?

No.
You can fit a 'B' intake on an 'RB' block using spacers but not the other way around.
However you don't have to. Edelbrock make a 383/400 six pack intake even though Chrysler never used one.
