Depends on weather you want your truck to run like truck or a car. I have a 77 360 with X heads and a 480 lift cam in my 78 D100 swb. Runs more like a muscle car than an old truck but that is what I wanted. I don't tow or haul heavy loads. I do a couple burnouts every so often though. So what is your liking?

You could do worse than the small summit cam.

The truck has headers and dual exhaust. Pistons are .070 in the bore. I use the truck for cruising mostly, with an occasional dump or scrap run. I am not opposed to a few burnouts per year.

These engines were always ‘under cammed’...
My mates 66 440 was totally stock with 452 heads and a 484 sixpack DC camshaft, went like a scalded cat...
I would recommend one step down and go with the 474...
Back in the day we would buy the biggest cams we could find!
Hughes engines are just going with the BIG cam theory now, 40 years after we did lol...
Big Is Best, don’t starve the beast...
I took a cam out of a 440 motorhome engine and it was 390 lift. The guy who ran the MH said, “it wouldn’t get out of its own way” lol...
Compcams 270 I think they call it now?
That’s a hipo 440 cam with 270 duration.

I'm building a 67 440 to put in my pickup and curious as to what cam I should go with. The engine has been bored .020, I'm using a flat top piston with .991 comp height and 452 heads. The block and head mating surfaces have not been cut. Best I can figure is somewhere around 9.3 compression using .020 steel head gaskets. Trans is a 727 with factory convertor, not really sure what it stalls at. It's going in a 77 D100 swb, 3.23 gears and 28 inch tall tires. The truck weighs 4100lbs with me in it. What say you. if it is below 9.5 comp ratio- on my junk I go with Hughes steamroller or whiplash cams. my 88-D100 with a bone stock 78 MH 440 with the Hughes 440 whiplash cam is awesome! very choppy but smooths out about1800-2000 rpm for the street truck. recurve dist.- fatten up the 650DP with a stock MH converter -any of my gears 3.91-3.23-2.76 turning a 29x15x15 M/T running the 2.76 gear at the moment for longer cruzing. sounds like a Funny Car cruz like a Chrysler New Yorker on the streets. idles along in 3rd gear 1200 rpm @ 25 mph in town choppin wood as they say. I run 2 Hughes "steamroller" roller cams in 318s and 1 "whiplash" roller cam 318 and 1 440-whiplash flat tappet cam all in trucks on the street. they all work well with low comp stock everything as advertised. fatten up the carb and recurve the dist with a set of 925B springs has been all that was needed with them. I have had the one SB roller cam in a few engines and over 200,000 miles on it now not one problem with them. got about 27,000 miles of fun on my flat tappet whiplash cam now. I am sure there are better faster cams out there but on lopo engines they work really well in traffic.

...while I haven't had it out on the main streets yet to see how well it does, the Engine Pro MC1787 is the cam I put in my 440 - it was what came in the engine master rebuild kit ordered from the machine shop). It idles smooth, and from the few hours it's been running /driving around the property it seems to have loads of torque. My truck was built to be a multi-purpose camping/rock-crawling rig that is also 100% streetable - it rolls on 40" Toyos with 5.38 gears. I found the engine buried deep inside a '79 Winnebago Motorcoach - it is a 440-3 block with standard 452 heads, and got a standard 'RV' rebuild with ~9-1 compression.

Thanks for all the replies. Years ago I had another 67 440 with the same pistons, heads and factory intake. It was bored .040 and I used factory HP exhaust manifolds. I ran the Mopar 274/474 cam. I had it in a Duster with 3.91 gears and factory high stall convertor. That car was fun to drive! I suppose the Summit cam would work for what I want. I very rarely tow anything with the truck and the 6401 cam doesn't sound like it would be too lumpy anyway. Also, I have a new one sitting on the shelf, that I bought for another project and never used is a plus. put that 6401 in it if you have it. they have a smooth idle and good torque; mimics a crane hmv278. you could do worse.

Any cam around 450 lift and 260 duration will work. But the LSA can have a huge affect on vacuum and idle characteristics of course! We checked a lot of cams and you rarely get ‘more’ cam than less it seems... If you buy a stockish 440 cam it will run good, but come the day you meet an F100 or Chev truck. You will wish you had the 474 lol... You want ‘bub, dee, blab’ not blah, blah, blah...

The standard Magnum Cam run good on the detuned engines since 72 ( is the cam on 400Magnum engines and lates 440 Magnums ) with 8:1 CR and open chamber heads. With given specs I think one step higher of the Magnum Cam will be fine. Crower 267 HDP maybe ?
