I thought my '66 440 had 325 hp and 480 lb-ft.
There's a difference between performance engines in cars and engines used in B-vans... also, your ’66 rating of 325 hp is gross, not net. Figure around 275 hp net.

If I remember right the 440 wedge head was never offered in the B-Vans anyway. I think the small-block 360 was the largest engine offered. I vaguely remember there being some ambiguity in published net horsepower ratings. I could be wrong but I think I remember the published net horsepower for 440 wedge head engines being 275 for compression ratios from 8.5:1 to 11.5:1. I wondered at the time how that could be. I think the motorhome chassis 440 had 8.5:1 compression with the same 275 or maybe 270 net horsepower.

I heard a rumor at the time that the 275 net horsepower was published for the higher performance versions to avoid a 300 horsepower rate-step-up threshold in the automobile insurance industry.

Nope, we had a 1976 B200 LE w/440 and 9 1/4 rear w/ 4:10 gears. my Mom had special ordered it to pull a heavy horse trailer.
Got about 14 mpg empty, 9 fully loaded for weekend trail riding. No lack of power. 0-60 in about 5 secs, and it was mean to camero;s and
chicken cars during the late 70's and early 80's

The 440 was available in the vans for a few years. it was rare, but it was offered. I'm sure the 400 probably was an option as well.

I definitely remember the 400 (LA), never saw a 440 version (RB). Having owned a 360 LA version, hearing that a 440 fit into the "doghouse" is somewhat surprising.

It was quite a tight fit. I helped a friend rescue a 1978 Dodge Street Van with the 440 and AC. It was very packed in the engine compartment.

Yes, swapping out spark plugs was fun, only 2 ,I recall, were accessible from the dog house, the other 6 from under the van.
But I loved that Thermoquad. About 3/8 inch of spacing between the heat shield and the floor of the van, both sides.

Bet the new vans won't pull that beast did, but they will pass more gas stations. :)

I pulled my 360 engine, up and out through the passenger door, Im guessing the 440 had to come out through the front?

Never had the opportunity to pull it. When speed limits went back to 65, Mom traded it, for an new '87, w/360 and a stupid quadrabog ( after about 70k miles)

Odd http://www.ramtruck.ca/en (Canada) doesn't show the availability of the ProMaster, just the CV Cargo, but http://www.ramtrucks.com/en (US) does.
