I've done some searching and there seems to be a lot opinions, but they all seem to be leaning towards max power. And for the most part using newer or large older carbs but I've been trying to fine a happy medium with near stock parts.
Before the 2bbl went back on there were long tube headers and an 850cfm double pump holley, ridiculous for what's there and what I'm looking for which brings me to now.
So the 2BBL runs well that I put on as a temporary carb until I worked out this 4bbl idea.
And now the only reason I'm looking to upgrade is I've also got that 4bbl intake and was wondering what would be best for my situation.
Currently the car is a 73' Duster Twister with a stock 318 with stock exhaust manifolds and stock 2bbl intake manifold. The only changes that have been made are a dual 2.5'' dual exhaust and a high flow air filter housing, with deleted vac lines and intake heater from the exhaust manifold. I'm not entirely sure what the 4bbl intake manifold is from (340 or 360) but it has the same stampings in the same places for firing order, cylinder numbers and rotation.
What I am looking for is low cost, better fuel economy, and extra power is always good. I'm not sure which size and model would be best, It was suggested that I use a 350cfm but said nothing else about it, another said to avoid Carter yet a third said to avoid Holley? So which is it? People say to avoid either one? My initial thought was a 450cfm Carter
I don't know for sure, and that's why I'm looking for some help. So what I am looking for is low cost, better fuel economy, and extra power?
Thanks
