Final Engine Compression Ratio?

YR, I had mech and vac. secondary's, Edelbrock and Holley in the past, also some Rochester quadrajets many years ago, this Holley I have now has been the best carb I have ever owned, I have the available jets, springs, etc. to tune, it is adjustable on all 4 corners and has the billet base and metering blocks,

I think a 750 would be better suited for this car, especially if I up the cam, another 600.00 plus though and I have also thought about it (770 version of what I havehttps://www.summitracing.com/parts/hly-0-86770bl )

Anybody looking to sponsor a new Mopar owner in the pacific Northwest? I will put your name in bold 1/4" letters on the bottom quarter of the car as appreciation! LOL


I personally won't buy anything with the name Holley on it. In several places on here I've related why I won't do it.

FWIW the Edelbrock and Qjet are not vacuum secondary carbs. They have mechanical secondaries with an air valve over them.

That's not the same as the Holley system.
