Hey guys I do mainly Forest Service trail riding since I'm a volunteer for the U.S. F.S. but occasionally I go with my club to some ORV parks. My 78 with a 304 has a two barrel carb and intake. In your opinion if I was to upgrade to a four barrel and aftermarket intake which carb and which intake would you install?
i did a edelbrock performer intake and 600 carb. if i was to do it again i would get the edelbrock intake and buy used holley and rebuild it. new carbs are ridiculously expensive imo. if you can find a cheap holley 600 with the side hung floats that would be a good way to go. i was able to get one for 25 complete carb.
My carb does not have a secondary metering block so i am going to get one with the transfer tube that you see in this the truck avenger carb pic. The transfer tube you have to call holley. a jet kit, gaskets, and maybe a couple other small parts which you can order from summit or wherever you buy parts. by the time im done i sould be around 200 complete.
Many folks seem to have good luck with that Edelbrock 'Carter AFB clone'
and that is what was on 'Black Betty' when I got her. Even after a rebuild/rejet (& rods) using Edelbrocks stats I couldn't get that card to run right. Ultimately after she stalled at a traffic signal a backfire through the card caused a small fire. (Thanks Heavens I had a fire extinguisher aboard). As luck would have it a couple of decades ago I sold my actual Carter AFB to a friend that was going to run it on his SBC project that never got off the ground.
This Carter had been on a 350 SBC with a very lopey cam and other speed goodies so I went with smaller jets and stiffer springs on the metering rods to adjust the metering and 'wha-la' she's been running strong ever since.

I am currently in the process of doing what you are asking. Edelbrock 2131 performer intake hands down. As for the carb I decided to go with the Carb Shop and have them build me a custom Off Road Holley. They take all your specs from your current engine and build it to those specs. Then then dyno it on their engine.
i bought a used edelbrock intake and a used holley truck avenger 470. i rebulilt the carb and only have about $300 into the set up and it has made a world of difference. You do not need a 600 CFM carb for a 304. my 470 makes plenty of power and sounds mean.
