HEY!
I saw this! LOL

Are you talking my Weiand 3x2bbl intake turned into a 2x4bbl ? The best carbs I ran on my truck were two 450cfm Holley center floats, I think they might have been the "Economasters" series but I'm not 100% positive.
I drove the truck year round, tons of torque, perfect drivability, and those two 450s on my Demon would pass AirCare emissions tests with flying colors, no detuning whatsoever....
I've used Edelbrocks too, which were OK, but those 450 Holleys really worked well for me. My distributor was recurved using two of the stock distributor "light" springs. Total advance was 34-36. NO vacuum advance.



Yes I'm going to run one of those old Weiand intakes on my 63. I plan on running Holley carbs were those 450 mechanical or vacuum secondary?

Thanks for the info.
