Sobrac,,
you seem to have experience with dual quads,,can you give me your opinion ?
My Builder {KeithCraft} is waiting on me to send carbs for my new engine.An alloy 496 shelby,Stage 3 eldebrock heads,tunnel wedge intake,should make in excess of 700 hp,cam lift is 740 ,,duration 244/247 if memory serves,dont quote me there.Ok Heres the question,I have a pair of original 780 cfm c5af Bu and bt,3410 and 3411 respectfully,the carbs are original and would need fresening or blueprinting.There still on an original no number med rise intake ,I hate to alter them much,and I wonder if there is a better choice for this motor ,obviously it should suck lots of air,not sure about 1580 however.I also sort of hate to put any thing used since I am in this deep,,whats your opinion ?
thanks,Tim
