Re: IML: Easy Fix

[sosmi@xxxxxxxxxxx]

With all the interest in performance, and gas mileage, I had a flash-back, on my first car, a64 Dodge Polara, with only 42K (in 1969) I looked for all the performance I could extract from that old 318. I added a 4bbl intake, and dual exhaust, it still wasn't the tire smoker I dreamed of, but it did run better! After that, the only solution, was more MOTOR. That came with a 383 RoadRunner engine-trans.And when we pulled the old engine out, we found the heat riser valve stuck shut, which means: ALL exhaust gases from passenger side cylinders, had to pass through the intake heat riser passage under the carb, to exit the other manifold. Well I guess I'll never know just how good that old 318 could have run,BUT I've had other cars with the same problem,  and I know how good they did run after, I fixed them.Just something to think about the next time your changing oil, and under that monster. Ya'll have a nice day, Dave.

If memory serves me, the intakes pre-67 are all small bolt pattern AFB. 67-70 used Holley 4160 type carbs(larger bolt pattern) Some 71's had a carter AVS.(I had one)And after that, it was changed to the Carter Thermo-Quad spread bore type. The height of the intake also changed, newer versions were higher.The choke wells also changed, in some carb, intake combinations this could be an issue.If , I'm missing something , I'm sure someone will will add to the facts.Thanks, Ya'll have nice day, Dave.
