so im building a 350sbc and am going to use a 4-71 and plan to put dual quad carbs. I was wanting to keep it period looking as in late 50s early 60s so was trying to stay away from using new Holleys(which i dont believe would fit the carb adapter anyway) or new Edelbrock carbs. I have been looking for WCFB carbs or AFB carbs but i dont really know what im looking for as WCFB carbs dont seem to have any kind of sizing. I think a pair of Carter AFB 500s would be OK but not sure if they would still be too much? or if they would fit the adapter - i believe they would though. I see the dual quad carbs for corvettes etc. but they cost an arm and a leg and im not prepared to pay 2k - 4k for them, i think thats crazy money. Does anyone running a similar set up have any recommendations? Also anyone recommend a decent cam? The engine is going into a Model A with a 5spd and a quick change if that makes any difference. thanks
dual quads on a 4-71? Hmmm...how about a single 750 AFB instead? WCFB will be around 400 each, depending on the model. Four 97s would look right on that, if you really want it to look right.
Macs makes this http://www.macsspeed.com/index.php/...t-intake-adaptor-471-blower-to-4-carbs-detail Here are some more ideas Hear is a dual4. I have wondered how well 2 Rochester 2v carbs would work on these.
I’d probably go with two AFB’s, they worked and look great on Tom McMullen’s roadster. The Weiand 2-4 plate is HTF though.
I already have a 2-4 Weiand plate. I have 4 97s on the shelf im not using either so i could use them but would prefer to use dual quads.
ive got dual 97s on my '35 roadster and a tri carb on my '35 coupe but ive never ran dual quads on anything. Haven't had a blower on anything either however one of my friend runs one and has done forever. The guy modifying my blower builds them for a living and has run them forever too so i have lots of support around.
I would try single first, get use to the blower. Then try duals. One new thing at a time. Less likely to have multiple problems to overcome.
