About 20 years ago, I was at a general car swap meet with very little Mopar stuff. I did find one guy with mostly Mopar stuff, and he had a SBM dual 4 barrel intake manifold. I don't remember the brand, but he was asking $125 for it and probably would have taken $100. I have been kicking myself in the *** for 20 years for not buying that. Even if a good single 4 barrel on a good intake matched the power of two 500 CFM 4 barrels, imagine how cool it would look!
