Rob;
I'm just switching to a pair of fans off a GM Lumina for my rad. I
already have a large oil cooler with a pair of fans on it. Now, I leave
my oil cooler fans on while fueling up on hot days just to reduce the
chance of vapor lock. The only disadvantage is you get cooked from the
hot air coming out the "useless louvers", while you are holding the
nozzle. I intend to have a manual override on the thermostatically
controlled electric rad fans, and also leave them on while fueling. The
thermostat is 185 and the fan control will be set to 195 as per
instructions.

Rob;
This is the torque curve I was speaking of. One that increases as the
rpm drops off. A good gas truck engine, with higher torque at 2000 than
at any higher rpm.
Here is what we really want;
"General Motor's Tonawanda plant, just outside Buffalo, New York, will
be the birthplace of GM's new 4.5-liter Duramax Diesel V8.
The clean emissions light duty oil burner will find a place in the
engine compartments of the Chevrolet Silverado and GMC Sierra half-ton
pickups by the 2010 model year. It's expected to be rated in excess of
310-horsepower and 520 pound-feet of torque. In comparison, the
6.6-liter Duramax, currently used in GM's heavy duty pickup, is rated at
365-hp / 660 lb-ft.
Look at a heavy diesel truck converted to LNG has for a torque curve on

Gordon,
I'd like to see the torque curve for Dick's engine from 0 to 2000 rpm.

just a though I did a little reading on the switch pitch tranny, it looked like it was a dual stall stage TC? so you could have a low and high stall converter?
was wondering has anyone though of moding such a tranny for a lockup type device, or if its even possible? locking a converter on long flat runs or slight grades would reduce tranny heat and improve gas milage...

I have a variable pitch converter in my "new" '73 23, but it either doesn't work or it doesn't make enough difference to notice. I tried to find some old test data, but I must have thrown it out. As I recall, the low pitch (forgot which we called "high" and "low") gave a stall ratio of something like 2.6 or 2.7, but it dropped off really fast. Then the high pitch was used to fill in the ratio a little bit. The 2.6 ratio gives great performance when you're standing still...:-). Actually, it's good for one thing and that is backing up a steep hill. The transmission doesn't have much of a reverse gear (2.08 maybe?) and if you find yourself trapped you might need the extra ratio. Not likely, though. I don't think it's worth it and never did. Oh, yeah, the standard torque converter has a stall torque ratio of between 2.0 and 2.1.

Manny did one , and found it ineffective.
Maybe he will report on it one day

I built some of the first experimental converter clutch units way back when. It's sort of simple and sort of difficult. Controlling it is simpler than you might think - just reverse the flow of cooling oil through the converter and the clutch comes on (and the cooling flow stops, but you don't care). It would be a big project as I don't think the THM 400 series transmission ever got them, but maybe after I left they have. I'd be interested to know. It would be a wonderful thing, maybe worth 4 or 5% in fuel economy.
