      Its an RB engine. And uh, a set of Indy cylinder heads would help it a bit

      What's an RB engine?

      A relative of mine just got an old Winnebago powered by one of these for free, It's his new winter project. It needs a new brake master cylinder, new tires, a radiator, and probably more small stuff. I'm going to take a look at it over the weekend.

      RB is a raised block engine, one of two groups of Chrysler wedge-head big blocks.

      "A" block is the 303/313/318/326 poly-head engines. The 318 and Canadian 313 were the longest-serving members of this group, the 318 until '66 and the 313 in Canada until '64. They were replaced by the "LA" block wedge engines (273/318/340/360) around '67 (in '68 for Canada).

      "B" block is the mainline big block wedge-head engines, introduced in '58 on Plymouth, Dodge and DeSoto lines. They were initially 350 and 361. In '59, the 383 was introduced on Dodge and DeSoto lines, and by '61 they were used across the board. The 350 lasted only one year, the 361 was dropped in the mid-60s and the 383 became a 400 in the early 70s.

      The "RB" block was introduced in '59 on Chrysler and Imperial lines. They were the 383 and 413 initially, but the 383 was dropped after '60 (it was only ever used on US-built Chrysler Windsor and Saratoga). The 426 wedge (not hemi) was derived from this, as was the 440. The 440 replaced the 413 and 426 wedge engines in '66.

      Ram induction was used on the 361 and 383, and the 413 and 426. It was introduced in '60 on the Chrysler 300F (375 or even 400bhp twin 4bbl 413), and as the "Sonoramic Commando" on Plymouths (dual quad 361 initially, 383 later in the year) and "D-500" on Dodges (ultimate was the dual quad 383).

      The big difference between the B and RB engine is in stroke and deck height, hence requiring a wider intake manifold. It may confuse you that there were two 383s, but the B block 383 was a bored out 361 while the RB block 383 was a de-bored 413. It was done initially for cost reasons, because Chrysler at the time ('59-'60) only used the 413 in New Yorkers, 300s and Imperials and it made sense to share things. But in '61, the RB 383 engine was dropped and all 383 were B blocks. Economic reasons for one, as producing two engines of the same size wasn't viable, and anyway the RB block engines (413) were starting to be used across the board by then.

      Canadian-built models had to share far more in common with each other, engine-wise, than their US-built counterparts did due to market differences (Canada being a smaller market and all). For example, the A block 303 engine used in the '56 Fury was actually a Canadian engine, used in '56 Canadian-built Chrysler Windsor and Dodge Custom Royal. Chrysler Canada also stuck with the 313 instead of switching to the 318 until the mid-60s. That's just some of the examples in differences, another being that the bigger Chrysler/DeSoto flathead six was preferred to the smaller Dodge/Plymouth one and used in all Canadian-built six-banger Mopars through to '59. Canadian-built '59 and '60 Windsors and Saratogas also used the B block 383 instead of the American RB.

      What he said

      But in all seriousness, pick me up a Ford 427 Sideoiler while you're out grabbing 400+ ci engines.

      The RB 4bbl 413 and 440 are without doubt some of the best big-blocks ever built, indeed the best real-world performers you can have in a car.

      While we're talking huge engines... at work we have a 70's caddy convertible with the big old 500ci V-8. And ohhhh boy does that thing lay down rubber like it's going out of style. A whole new exhaust system was just put on it and when you rev it up it sounds like a F1 racer. It screams!

      Am I correct in saying the caddy 500 was the largest production engine? Anybody have the numbers on this animal?

      So what kind of output could one expect from a Dodge 440?

      What kind of performance do you think that would create in a 15,000lb-20,000lb RV?

      How much does a V-10 TDI crate engine cost again?

      A MOPAR 500 cubic inch 505 hp Wedge is about 8900 bucks. Thats basically a longer stroke 440.

      Viper motors are 14000-16000 dollars.

      Not sure the output in a RV spec 440.

      The 440 when introduced was originally rated at 350bhp, but could go up to 375bhp though undoubtedly it could have been more. No doubt, with the 727 Torqueflite and 3.23 rear end it moved Chrysler's biggest and best cars along at unbelievable speed

      Yee Hah!!!
      This is the engine that powered the General Lee from 70's TV show The Dukes of Hazard. So it's GOT to be fast!

      Seriously, I have heard from people I know who have owned them that these are great engines. I assume that being from a motor home its a 4 bbl carb, but you'll want to upgrade to a 6-pack straight away.

      A late 60s full-size Dodge with the combination (440, 727 Torqueflite and 3.23 rear end) was tested to do 0-60 in the low 6s, quarter mile in the low 14s and top speed in the high 140s. That in a two-tonne full-size cruiser, unbelievable! Plymouth, Chrysler and Imperial wouldn't have been different from that. They also rode and handled well for their size, in fact considerably better than a comparable Ford or GM car.

      The Chevy 502 has never been offered in a production GM vehicle. The 496 is offered as the Vortec 8100 in the 2500HD. Prior to that the 454 was the largest Chevrolet offering, 455 in Buicks, 455 in Olds, dont know about Pontiacs (421 maybe?). 460 in Lincs and Fords.

      Bore is 4.25, the stroke is 4.37, 496 cubes.

      502 is 4.466 x 4.00

      Same Mark 6 block though.

      The Caddy 8.2 liter was a low compression motor making about 190hp.

      The 440 was a great motor, however, towards the end of it's career it was decompressed as well.

      The big block era was pretty funny if you think about it. Brute force. Not really complicated.

      I have had several big blocks in my time, and the Chryslers motors are pretty damn solid and when "built" they are stout.

      I never really like the Ford big blocks and I consider myself a Ford guy when it comes to American. Lots of low compression stuff. The 460 needs SVO heads minimum to even think about making any power.

      The 454 Chevy was a nice motor. Responsive and torquey even in decompressed form.

      Stock the 68-70 472 Cad had 375hp and 525 ft lbs of torque, while the 1970 500 ci had 400 hp and 550 ft lbs. Then they got smogged out. But getting a smog motor (lower compression, not as good heads, etc) and putting the 68-70 heads on it will result in instant 12:1 compression race gas territory. Stock intake manifold is a beast though, 54 lbs. Edlebrock makes a 4 barrel intake for the Cads, and any 429/460 Ford intake can be modifed to fit as well. The 472/500 Cadillacs are know as Lux motors, or The Lux.

      Not to mention these motors when equipped with headers and an aluminum intake weigh comparably to many small blocks, and not big blocks.

      I've a friend who's got a Cadillac 520 built by CMD that is expected to make about 600 hp and 700 ft lbs of torque at around 6500 rpm.

      Ford has at least three different groups of big blocks:
      - one was the MEL range- 383, 410, 430, 462- used in Lincolns, Mercurys ('58-'60) and Edsels ('58).
      - the famous FE range- 332, 352, 390, 427, 428
      - the later big block range (don't know its name)- 400, 429, 460
