One has to wonder "what was he thinking" putting that stove bolt six into the D. A 250 or 292 I could see as an upgrade, but a babbited bearing stovebolt is hardly an upgrade! I know the powerglide 235's had insert bearings but most of the sticks had babbit.

Just thru it out there, good body on the D

I agree, and my comments were nothing against you, just huh? Some swaps make sense, others seam to be done just because they have the engine, not any good reason.

Nice looking truck, Too bad they put the cheby six banger in it. I think the value would be higher with original motor!

I agree, those babbit bearing motors are undesirable. The ad does say 'gm' engine, so there's a chance it's a GMC engine. GMC switched to a pressure oil system years before Chebby did.

I could be wrong, but I didn't think GMC ever had a 235, I thought theirs were all bigger displacement.

This is what I found with GOOGLE.

I found that to be very confusing. I have hands on experience with a 207 and 216 both were babbited bearing engines. They didn't go into much detail and didn't call out the different blocks to well. I know GMC made their own and that they were different then the CHevy engines of the time.
Nothing wrong with babbit bearings, but dipper tubes were way out of date by the late 20's. Look at what IHC was doing by that time, They had started the wet liner, insert bearing design by the early 30's and those designs lasted until the late 60's to early 70's by which time diesels were coming on strong.
It is interesting that when Chevy was done with the 235, they sold it to Toyota for their 1st gen Landcruiser.
I will say in Chevy's and GMC's defense, they jumped to OHV well before Ford and Chry and in the truck market White. REO, IHC, Diamond T Kenworth and others were using OHV's by the 30's. IHC used and outside designed flathead (HD, GRD) but their own designs were OHV. Hall-Scott had OHC engines at this time, Auburn and Cord had superchargers.

Don't forget that Duesenberg was producing DOHC engines in the 20s.
