318 Four Barrel Intake

Very true, but go back and read my post again about the 340 intakes on 318 ports. Bottom line is while agreed there will be an impediment to flow, it will "work" forever, it won't hurt anything and the car will likely go quicker for less money. I sold my original Ram 4bbl intake/thermoquad to a co-worker with a '73 318 powered motorhome, he simply wanted more power. Again, port mis-match but he was thrilled with the power increase and will not sell the combo back to me. He would have spent far more money to get a "proper" intake to match his ports, and would have ended up with less power as well. I currently have a very well ported set of RB heads in combination with a stock 440-6bbl intake, there is indeed a mis-match but I did not want to alter my original 6bbl intake. Heads alone gave me .70et and 8mph and I can't imagine careful matching of the ports giving the performance increase to justify the time involved. Not saying it wouldn't give an increase but it could also have taken a lot of time and not given anything. I am sure there are many Max Wedge "clones" out there running the correct crossram setup but with only stock B/RB heads. Again, port mis-match but even so it will likely outperform any other 4bbl or 6bbl intake combo, port mis-match be damned. Just saying you don't have to have matching ports to acheive desired results be they economic/appearance/performance.
