Unported head quickness?

Not the fastest, but here are a couple of different looks to some different stuff. A) 1968 Ply Fury III 4-door. 100 % factory 383 commando (even exhaust and carb), 3.23 gears, auto, 4350 lbs with me in it, 15.19 1/4 mile. Added 3.55's and a Weiand action plus, 14.75! B). 1989 Dodge D150 shortbed 2wd. Came with a 3.9 TBI (non magnum) auto, 3.21's. All I did was install a '89 360 TBI (non magnum) and ECM from a '89 Maxi, with a balanced flexplate. 100 % stock from the Throttle body to the oil pan. Even used the factory 360 exhaust manifolds and single exhaust (bought a new Y-pipe). 15.32 at 87 mph. C). '85 Caravelle (k-car) 2.2 turbo. 14.60's with the only additions of a 125 dollar MP computer, and a 3.00 fish tank bubbler on the waste gate to run 14 psi of boost, and a 40 dollar home made exhaust. None of these odd ball combos had ported heads. Just cheap fun. Gave 1300 for the Fury, 900 for the truck, and 200 for the Caravelle.... THIS IS FUN ON A BUDGET.... LOL
