Used Rock Auto in the past but will not any longer. Under NO circumstances can you talk to anyone, really sucks. Wish they had not changed their policy on returns/problems. Ordered a complete A/C system for my truck and one small part was broken, it would have been easier to decipher the Rosetta Stone than getting the part, orifice tube extractor, replaced.

I think the requirement in Mo went away because hunters of all stripes, bird, coon etc, sued to remove the requirement because of dogs being stolen because when they parked their trucks to hunt the bad guys had their address from the truck. Could be true.

Jeep kept the 4.0 six through 2006 in the Wrangler.

Rock Auto does or doesn't?

I cannot say definitely that MOPAR used them, I am only 90 per cent certain. My father had a '55 Plymouth with overdrive and I think he referred to it as the "heavy duty" version which I suspect was thr R=11 given Chrysler Corporations long association withe Borg=Warner 3 speeds.

Look for a R11, has 4 pinion planetary vs 3 pinion in R10. Was used behind lots of V8's.

Could have been a military truck, such as aircraft "Follow Me". U.S. models had the sign on the tailgate.

No boxing needed, never been a 318, stock or or otherwise, that will compromise a pilothouse frame. Spend the time and money elsewhere.

You are spot on with the work involved but there is nothing that is not normal to ANY swap involving a non stock engine and or trans swap, at least in my 50 yrs experience. Easiest way is to remain stock, just depends on ones skill levels. Nice truck, if mine, would keep original drivetrain, old Mopar flatheads are great engines.

I agree with the statement of "not cheap" but in no way is it not simpler than what the OP was thinking of doing.

St. Louis Craigslist has a new dual carb manifold and dual Fenton headers, carbs included for a reasonable price. That would wake up your engine and someone probably makes an adaptor for the 904 trans. Easier way to go. Type in "flathead" and the ad comes up, in car parts.

Desoto is the least desireable hemi to use, all by itself when it comes to aftermarket anything. The only thing interchangeable is the incoming air. Desoto hemis were as good as Dodge and Chrysler but are still orphans. Unless you are willing to spend BIG$ you will have way less performance than you would with a later LA engine. Visually very cool.

Just buy motor mounts for putting Chevy V8 into a Jeep CJ, very easy.

That engine is totally shot, too expensive to fix. I will be by with cash for truck at scrap price +$50 and take it off your hands, no use throwing good money at it. Actually just envious...keep it in the family for sure.

2.8 is a gutless wonder, very low torque especially down low in RPM range. 292 has GOBS of torque and is a truck engine.Easy choice.
