2 barrel , 4 barrel, whose got the answer?

[krazykuda]

I have a great 4 bbl intake that would be perfect for your application... An offenhauser dual port dual plane intake for a spread bore... I will have to find it and post pictures....

yes please! I am looking for the 2 barrel but it would be great to do this all one time. let me kknow pleasew. and just a fyi, im not one to check every hour, more likely perhaps once a day.

bear with me please: 1983 318 stock, in a b250 van (concversion). because it is a lean burn (that doesnt work any more) it ios being converted to a hei ignition system with vacuum advance ( the gm hei module). the present carb (2 barrel) doesnt have a vacuum port to run the vacuum advance. so the coice is to either replace the 2 barrel (2280 holley or carter bbd), pull manifoold and change to a 4 barrel, or some combination. in a ideal worl i would change to a spreadbore and run either a thermoquad or quadrajet (550 cfm). since i havent started taking anything apart im open right now to considerations. this will be low rpm use (4500), hoping to gain better mileage (arent we all) as well as more power.
to summereize.\, a stockk two barrel on stock two barrel manifold, a four barrel on that 2 barrel manifold, or a 4 barrel with a 4 barrel manifold.
interested in your thoughts if you please. i also appreciate your time in responding, thanks

SOrry it took me a while to get back, I was busy for the holidays...

Here's an Offenhauser dual-port dual-plane intake that is made for a spread bore... The theory behind this intake is the bottom ports are for the primaries and the bottom ports feed the secondaries, so the secondaries are insulated by the primary ports and get the cooler/denser air/fuel mixture... It is great up to 5000 RPM and gets good MPG and is good for a stock 318 engine, especially in a truck or van...
