Thanks
My F250 only has a 302 Cleveland, not a 460 BB, what kind of front springs would I need for half a ton of cummins diesel? Iam an army engineer and I had a look at one of our machines today, the LET (Light Engineering Tractor) and it has a turboed 6B cummins. It looks like it would be a tight fit with the radiator an all. Would an electric fan save any room?

It is a tight fit. My rear valve cover is about 3/4" from the firewall and do not have room to run the stock fan and radiator. The '93 Dodge radaitor has been recommended to me, but I am not to the point of deciding that yet. It may hinge on a stock hood and fenders vs tilt glass front end. My plan is to run electric fan(s).
I plan to run the stock springs with one full leaf added and arched about 4" or so match the highboy rear leaf spring blocks.

I have plenty of room and I also used the 460 Fan Shroud after some mod work. I had another guy tell me that I had to use electric fans, All I can say is he IS WRONG..

cummins/ford conversion
A problem I have, Clutch /Tranny problem that is, I have a 1989 F-350 4X4 crewcab, powering this unit is a 1990 5.9 cummins with custom intercooler, 4" exhuast, tweaked V.E. pump, larger injectors, 16cm turbo exhuast housing and a few other tricks mated to this cummins is a ford 5sp ZF-S542 tranny, my problem is this, 1st clutch went at 219.000 miles, replaced this clutch with a rebuilt unit, this clutch went up in smoke after 1 mile running empty. upgraded to a 12" pressure plate with a 12" ceramic button disc, upgraded tranny to a heavy duty ford 5sp ZF-S547, My problem gets worse from here on in, The motor stalls out when I release the clutch (In any gear) including neutral, My best guess is a siezed input shaft bearing or very poor alignement causing the input shaft to bind, ( This tranny just cost $2400.00 dollars) my problem gets worse, Tearing tranny and clutch out again, (3rd time I'm getting good at it now) The tranny will not I say will not seperate from the flywheel, my guess again is the input shaft is seized in pilot bearing ( new pilot brg & input shaft) maybe stuck in new disc no way to get it out to inspect, Any PRO's out there wanna give it there best guess, Since new tranny installation zero miles on unit
