Inliners International Forums General Discussion Engines new project! am i crazy ?slant six?

Hey guys I recently finished my 46 chevy with the 292!
Apparently I didn't learn my lesson and bought another project truck. A 46 Dodge pickup. I am kicking around the idea of doing a slant six. I have found several in my area for sale on Craigslist, should I be talked out of it??????

Heaven's no! There is a lot of neat parts and speed equipment around for those motors and I understand they can be built to really run.

I like the Chevy. But there is nothing wrong with building a good Slant 6.

I think my main concern is the availability of parts. The engine I am looking at is out of a 66 Coronet. Are water pumps, pullies, etc. etc. still out there? How about cam shafts and rebuild kits like gaskets and stuff?

Based on what I have seen on the web there seems to be ample parts available. There's even some speed parts to be had Aussie Speed Shop.

It is still easy to build up a slant six. I think slant sixes are slightly longer than Dodge flathead sixes so you might have some challenges fitting one in.

Is there a certain slant engine I should be looking for? I know there is an aluminium block slanter that has rreally thin cylinder walls that does not leave much room for opening up. But are all the other steel slanters the same. My local pick and pull has a 68 Coronet 440 with a slant motor the guy wants 400 for the engine and automatic tranny. I have know idea if the motor runs.i was planning a whole new re-build anyway. Sorry this may seem like a dumb question, but I am a total newbie to the slant world.

CNC Dude should be here any minute. He knows a lot about slant sixes and even made some speed equipment for them I think. They still have a big following and some sites dedicated to them. There are some old posts here if you can find them. There was a triple carb version in Australia that made over 300hp. They were not available here. They are a good choice.

The slant is longer than the 218/230.
You want a 225, which is a tall deck (10.68") engine (which is why the slant: hood clearance).
The 3 X 1 Australian engine isn't a slant 6 but (almost) a hemi, no parts interchange. Nice engine but I've never seen one.
The 225 block won't support as much power as it can develop, something less than 400 has been reported.

Easiest: Eaton M90 from a GM 3.8 V6.

There are 2 different automatic transmissions for the /6, depending on the chassis. Compacts get the small 904, full-size cars and trucks get the stronger 727. Both can be upgraded for reasonable power levels but the 727 (longer, heavier) won't need anything but a shift kit (I use TransGo) and a converter, the 904 uses less power but gets expensive very quickly.
What I'd be looking for: a wrecked Dart Lite or Feather Duster, which have 225 engines with aluminum intakes, and 3 speed + overdrive manual transmissions (based on the very strong A833 used in the 440 etc.).
Ratios:
1st 3.09:1
2nd 1.67:1
3rd 1.00:1
O/D .73:1

Look for a 225 as panic has suggested. These engine have a good history for being durable and reliable. HP is easy to upgrade to a point as already mentioned, so just keep it simple and reliable and you'll be more satisfied.

A Coronet almost certainly has a 225 + 727 transmission, but I don't know ho to tell except for examining the pan shape.

So heres the one on CL I am looking at.

Heres another with a 904 tranny. But wouldn't this one be different as it is a 1979? I thought I read somwhere that the bottom end parts are different post 78?

The coronet in the junkyard I can have for $400 motor and auto tranny

At 56 years old with 2 bad knees manual trans is out of the question.

heres another looks to be in rough shape. but that can be cured with a trip up to Larry's Power just like my 292.

sorry......

There are differences between the forged crank engines and the cast crank engines as well as factory solid cam and hydraulic cam engines, the blocks, cranks and connecting rods are not interchangeable, and the valve train isn't a direct swap one to the other in regards to solid vs. hydraulic. So you'll need to verify this before you order any rebuild parts.

Put a 225 in a 48 Plymouth coupe had to make slight firewall changes plus made new inner fender panels, bored .030 over, mild cam, alum intake with 4 barrel, headers ceramic and wrapped. Alum valve cover and MSD ignition, 727 trans, Mustang rear end. Runs like a small V8 and blows peoples minds at shows.

All of the original engines (170, 198, 225) rebut the "rule" of tuned length runners: there are 3 different lengths in pairs. I've read that Chrysler designed it to provide some ram effect (long runners, entering the port close to 90 degrees) but different lengths to broaden the torque curve.

That 79 engine might have the 904 with the deeper first gear that would help get that truck moving. Worth checking into IMHO Jay
