(99.195.97.206) | 35 is about to be the new 50. What this means is when the Chrysler overdrive transmission is put into an FMC the engine speed will be reduced saving lots of wear and tear but the important thing to realize is that the engine will need to produce the power at a lower rpm. What once pushed you down the road at 65 mph (3200-3400rpm) will be done with just 2250-2300 rpm. The current FMC engine thinking will have to change from the "more is best" thinking to the building of engines producing max power at lower rpm than most aftermarket parts are designed for.
About to install a special built Chrysler overdrive transmission into my FMC. I know of a couple other owners that have already done so. Here are some thoughts as to the different requirements on the engine with the overdrive 4spd.
I realize that in the past FMC engines were needing power at a higher rpm and as I have said in the past, " I love driving my FMC down the road at 4000-4500 rpm" the 440 however does not. Is it time to shift into overdrive and retune your 440 into the low rpm torque monster is once was?
Most shops are geared to building high horsepower engines for light weight cars, not 15,000 pound (pretty) bricks. I can hear them now... I can get lots-O-ponies out of your 440!
Well do it under 3,500 rpms and we'll talk.
As for the line 35 is the new 50, With the overdrive, what used to be 5,000 rpm is now 3,500. Build your torque down low and run with an overdrive. Save on engine repair and I have to think, fuel costs.
