| 352/390 exhaust question |
| By RICK C - 02/18/2002 11:14:34 AM; IP 12.34.246.4 |
| i have a 66 f100 with a 352 converted to a 390 (crank, rods and bore). i am still running the heads from the 352 2v truck motor. i changed to a stock ford 4v cast iron intake and a 600 cfm holley. this is a street driven truck / not a drag racer. i am also still running the exhaust manifolds from the 2v with 2 1/4 in dual exhausts. would i be wise to get a set of headers to improve the flow. would i see a big improvement in performance or would something else be a better investment. i have changed the intake manifold gaskets to the felpro type that block the exhaust crossover through the intake manifold and it seems to have decreased the power. does that sound logical. any advice appreciated. rick |
