What carb are you running?

I am looking for opnions on carbs..... I have a spread bore 4 brl on my 318 but it didn't come with a carb. I guess they came with a theormal quad? I have a q-jet off a gm truck and a Holley 0-6210 650 cfm or should I keep looking? The q-jet kinda scares me... its being held together by 3 different kinds of bolts, phillips, slotted and a star looking thingy... Gee wonder if thats been rebuilt a time or 8

I run a 600 edelbrock on my 307

I'm running a stock Carter BBD 2BBL on my 273v8, now manufactured by Holley.

I've been hot rodding for years and never had good luck with Holley's or Quadra-Bogs. I've always had good performance with Edelbrock 600cfm square bores (vacuum or mechanical secondaries, I prefer mechanical) and I run them exclusively now if I have a choice.

Of the two that you have there I'd probably go with whichever had the least CFM (a fairly stock motor doesn't need much over 600) and whichever one I could get the cheapest rebuild kit for

Rebuild one of them and try it, if it doesn't work out try the other one.

Edelbrock - approx 650cfm - on my 360ci





Had it professionally rebuilt, and it kicked into life immediately. Was on the truck when I bought it, and one float was full of gas. All good now.

I got a 600 edelbrock on my 327.....

I will give a vote for the edelbrock, take out the box and run it. I run these on all the work trucks (WAY SIMPLE)

the intake you show no doubt had a q-jet on it new by the looks of it. had lots of them intakes off in 30 years of wrenchin. but the carb kiwi shows is the same design as was used in the early 60's on a lot of manufactures cars. then it was know as A.F.B. carbs but if you ever needed a quick trim look over the top of one and crack the throttle plates open a couple times. we affectionatley called them All For Backfiring. now edelbrock produces them and they are the simplest carb to maintain and you can tune them quite a bit if you know how. now don't cheap out and buy a good used one from flea-bay just spend the cash right the first time and get a new one. watch out for the factory reman units too cause they went back to the factory for a reason..... stock 318 or 360 will work great with a 600 cfm edelbrock.

Definitely go with a 600 cfm edelbrock, plug and play and lots of tuning options if you need.
