All slant six cranks were forged up until '75. In '76 most were cast crank, different bearing dimensions, no internals interchange with forged as far as I know. The offset design of the slant allows really long stroke, long rods, long intake runners and a lot of room on the lefthand side of the engine for steering linkages, custom intakes, turbos, dry sump tanks, whatever. A slant six offers more in near-stock configuration than the Ford 144-250 or the Chevy 194-250 in my opinion.
I understand that Clifford (and others) have parts for that to really make it sing. If you're putting it in rod or a custom though, it needs a couple carbs and a dual exhaust. It would probably be easier to find parts for the 250 in BFE if you needed them.
/6 was used up into the 80's. There are lots of support to parts chains. Some part even interchange with the V8's, like starters.
Jeep/AMC inline six STOCK exhaust manifold, new they are only $60 on e-bay. this is a split manifold STOCK and is made of Stainless Steel. Using this engine in a Old car that originally came with a Inline 6 makes sense. arnold.
here is a pic of stock ford 300 6 cyl exhuast manifolds,,they are split stock and only $50 new on e-bay
Stock for EFI lower intake manifold for ford 300 6,,could easybe made into a tri-power manifold by bolting on a plenum made of recttangular tubing. arnold.
another pic of the stock AMC/Jeep 6 cyl 2 barrel carb manifold,, that could be converted to tri carbs,, EFI manifold for AMC/jeep 6 that could be converted to multi carb set up
I'm with Tricknology, my dad had a 4.0 Cherokee back in the late 80's and that thing was tough, pops drives really hard and he broke Blazers, Broncos and Tahoes, but not that jeep. He used to scare the **** outta' me with that thing off road! They have a nice flat torque curve it always felt like it was ready to jump and jump it did. Mileage was not bad either. My ex-girlfriend had a new trailblazer and that engine had same characteristics as the jeep but even a bit faster, it impressed me alot but I like the idea of sticking with mopar. Ford engine in mopar car just feels wrong to me, just my .02
Danny, I didn't read all the posts, as I'm in sort of a hurry, but I've got an aluminum block slant six with a fourspeed hooked to it. out of a '62 Valiant, pretty cool. Let me know if you decide to go with the crooked six. Animal
Yea this is an old *** post.... i ended up buying a complete 84 chevy pick up with a 250 and a 3 speed. i had to put chevy into this mess of a project some where. so i got that with the wonderfull intergraded head and stock split manifolds and i picked up a n.o.s. holley economaster 1bbl for it. still have yet to figure out what ratio my rear is on my dakota ch***is. the 250 fits ok into the engine bay had to knock the firewall back a bit.
Although the question is chev vs Mopar, has anyone used or considered a Jag 4.0 or 4.2? That DOHC has lots of cool factor. I know that the used car market does not treat the 70's and 80's sedans with any respect. I recently bought a complete 87, drove it home, all for $900. (The front and rear susp is for a project)
I think we all know what I would say. http://www.jalopyjournal.com/forum/showthread.php?t=287018 You can still find Offy intakes for the slant on Craigslist for 100 bucks. Ebay gets retarded on prices for performance slant parts.

Someone fill me in (PLEASE)............... I have a very sweet 1950 Plymouth Coupe, but I want something with a bit more power so it's more of a highway speed ride. If I used a Ford 300 with a C-6, which I have tons of access to many, will the combo "Fit" without issues of ANY kind?. I don't want to be cutting the firewall up. And would anyone, by chance, know of a company that does a swap mount system to accomplish such a change? Thanks!
not likely that you will find a "kit" to do an oddball swap like that. Do you have access to a tape measure? so you can measure the engine, and the car, and see if it will fit? my wild guess is that the Ford engine will be several inches longer, and won't fit without getting into the firewall and/or relocating the radiator forward, but that's just a guess, based on having fiddled with old cars for a long time. A V8 of some kind is more likely to fit, but will likely require some finagling to get around the steering box. And you'll find that the brakes are not really up to the speeds you want to travel, the rear end will need to be swapped, etc.
You would need a big hole in the firewall. Those Ford 300 engines are very long. Sent from my SM-T350 using The H.A.M.B. mobile app
I'm not understanding the flex joints in the front and rear down tubes. Since there is no "mechanical flex" between the ports I ***ume this is to combat expansion & contraction to some extent but mainly the initial hook-up since the ends would be free to move where they needed to go. Interesting but necessary? I suspect the negative affect to exhaust flow would out weight any alignment benefits. - EM - EM
I currently own one 300 Ford, great engine, 150k on it and it runs like the first day it was built, uses no oil but please don't use decent gas mileage to to compare it to a slant-six. Slant-sixes are much more fuel efficent, not as powerful but much better at mpg. I have owned several of each type over the last 40+ years so I am speaking from real world experience.
My thoughts. I had a 1970 Duster with a slant 6, Lunati race cam , Offy intake , Holley 4 barrel,headers, 4 speed with a 3:55 Suregrip. Engine bored 30 over. Go cat go. I agree with dependability with a six. If you want gas mileage than disregard my spiffy six specs.
