Have a 77 Ranchero with a 351M. Wish to find out if Holley Dominator 4 bl intake will fit this motor?
Have rebuilt the 600 Holley carb with electric choke, and wish to get this set up on the truck along with a ProComp HEI distributor.

 

Umm
The 600 is on there now and you want a dominator on later...
What mods are done to the engine.
A dominator carb is typically a race only carb.
If you ment you wanted an intake for that 600 and not the factory 2barrel, the 600 isn't a dominator carb.

Summit racing sells all kinds of 351m intakes, but I don't think anyone sells one that has a 4500 dominator flange.

 

Thank you, I got an answer from Holley. The 4 barrel manifold I have is part number 701R-20 and 300-20. Holley says it is for the 351M, Cleveland and 400 street performance.
The carb, a Holley 600 cfm with electric choke is right for the manifold and the use I wish for it.
Not looking for high rev's, drag performance, just an increase of a bit for a slow rev motor, etc.
Will install the dual exhuast and the HEI ProComp distributor and should provide what I desire for a crusier type of Ranchero.
Thanks again for all's input.
