I am working on a stock 1968 318 in a dart. Its been a project for my son the last couple years and hoping to get finished before he graduates this spring
The original 2 barrel needs rebuilt and i think we will put about a 600 holley 4 barrel on it instead. I have not touched the one on my dart in almost 20 years.
I have an edelbrock intake for a spread bore but never had a spread bore. What is the benifit? Better fuel mileage? i know holley has both styles and i only want to stay with a holley because i can tune them allready.
Its not getting raced only street driven. But i am sure he would still like to have a little fun going through the 4 speed,i know i do.
Just need some carb advice. I have a fresh 750cfm 4160 holley. And also an old 570 cfm holley from a 68? 440 i rebuilt a few years back that i am not sure works right yet.
Of course i could look around for a different one if needed.
