According Car Craft magazine, the following automatic transmissions cause the power losses bellow.
Powerglide - 18 hp
TH-350 - 36 hp
TH-400 - 44 hp
Ford C-6 - 55-60 hp
Ford C-4 - 28 hp
Ford FMX - 25 hp
Chrysler A904 - 25 hp
Chrysler 727 - 45 hp
How much power would be lost with a Muncie 4 speed?

these things are a mess. I hate magazines sometimes. Please realize that transmissions (auto or stick) do not eat a set amount of 'hp.' You need to look at how much power the engine made alone, and figure out the PERCENTAGE.


Id say substantially less; if you run 1qt of oil (all you really truly need) in the Muncie and its in 4th gear (direct drive) and its in good shape, probably not much at all. Want to guild the lilly? take just about everything off the mainshaft and cluster, practically remove reverse, get one of our gundrilled mainshafts, use a small clutch and flywheel, 1qt of Royal Purple MAX GEAR in a 90wt (you only really need 1qt in a Muncie honest....and astound your friends. And that hasn't even touched on REM processing and cryogenics

Since theres no converter to fill with fluid, you're looking at a lot less mass. Even more if you can lighten the geartrain some.

Our rollerized 1st gear will help some as well (when you're not in 1st gear) although this is mostly to ward off heat than free up pumping losses

What are you trying to do is a better question.

It seems that I did not try good enough...
