RE: 318 Poly refresh time - Cam and gear drive info, please

["Raymond J. Henry" <62Dart@xxxxxxxxxxxx>]

Not worried about the distributor. I've dropped in an electronic distributor and all from a mid-70's pickup. Chrome ECM, which is kinda pointless on the existing 2-bbl carb, as I could never get enough flow through that carb to allow 6,000 RPM. At any rate, it runs like a charm. So while I may have someone look at changing the curve (after we see how it works in the new engine), I'm probably just going to stick with that set-up.

I am, however, raising my eyebrows a bit at reported mileage. I'm already getting ~22.5 miles/U.S. gallon, and was hoping to better that. I've had no shortage of cars that got better mileage, including a '67 Newport with 383 4-bbl factory single exhaust, '71 Polara 318 2-bbl factory single exhaust, '57 Dodge Mayfair 303 2-bbl 3.5" exhaust w/340 mufflers, etc... All stock engines. I was hoping that with the right cam, the dual exhaust, and the electronic ignition, I would be abler to get closer to 30 MPG. When I got the car, it had a 6 1/2 cylinder 318 poly (yes, one completely dead, one half dead cylinder) with exhaust that nicely matched the blue interior, and it got over 20 MPG. The engine I have right now was a low hour rebuild from a farm truck, running one car & one truck head.

Ray, I had a new 65 Belverdere11 with 318. 3-speed, 3.23 gears in school. I installed a 58 318 cast 4 barrel carb intake and the 58  AFB. I installed duals with turbo mufflers and a floor shift. It ran OK but not that great. 
In 65, no one made advance kits. I pulled the distributer and slotted out the advance weight slots and used needle nose pliers to stretch the advance springs some. I left the vaccumn canaster stock and connected. I really got lucky with that combo. I could outrun any 383 auto or 4-speed from 0 to 100. 
I never got beat. My milage was 21-22 mpg. I would suggest keeping what you have, less gear drives, pay close attention to your valve adjustment and send your distributor to Don at FBO Systems to have your distributor recurved and set up. I think you'll be surprised and pleased at the power and good gas millage you'll have.  Hope this helps
