[QUOTE="swampratt, post: 3732308, member: 15054"] I built a 302 Ford .030 Over and ported the weeak heads circa 1982. Stuck a 260H comp cam in it . Ported the 2V intake and ported the exhaust manifolds. This was the new family wagon. Full size E150 ford van at 6000 lbs with 9" rearend and 3.50 gears. My goal was 20 MPG and it needed to last. It did last me 13 years and got in the 19 MPG area but never got 20. Normally it got 17.6 in town or highway and got that 17.6 pulling my 15 foot Bayliner. I tried many carbs as I owned over 60 carbs at that time. Down to 1/3 that in decent ones now. Did not matter what carb I stuck on it after I tuned it for best MPG they were all within 1/2MPG of each other. 750 QJet , 750 AFB, 625 and 465 AFB, 600 Edelbrock, Holley 390 economaster (POS for power). a few different sizes of Motorcraft 2 barrels. I tried hot air fed air cleaner assemblies and cold air open element. No difference there. I stuck with the Motorcraft 2 Barrel. That has got to be the most reliable simplest carb on the planet. You do not even need the top air horn on one to make it run. Better operation is a must have and you can get that with an edelbrock or AFB style carb and you do not need to have the secondaries hooked up on them either. My vote is a motorcraft 2 barrel or the above. Port the intake you have if you never find a good iron 4V intake. Now watch the runner sizes on the 318 intake they are much smaller than the 340-360 runners. Not an issue if you are not looking for utmost power. That smaller intake runner deal may add velocity and actually help in the low end TQ department. I have not been there to try that. One big power maker and MPG maker is a quick timing curve. I usually set my engines up at 18-22 initial timing and I want all my total in by cruise RPM. Total will be different for different engines. My ford liked 35 total..anymore and I would get pinging any less and MPG fell off a tick. Raced a buddies 1991 350" chevy 4x4 Truck he had Throttle body injection electric fans headers and throttle body spacer and stage 2 chip. His ran 18.2 in the 1/4 and My smaller engine Van ran 18.0. I had a tank full of 91 octane and told him if he beat me I would flip the switch and run on that tank (dual tanks) add some timing and we would race again. Never had to flip to the 91 octane tank. Yea 18's in the 1/4 seems slow but these are heavy and not built for racing. Fun though going down the track with a van with curtains in the windows. [/QUOTE]
