I am going to be running a 904. Believe this is the pan that came off my engine.

Not a big problem using a 68 or newer engine with a 67 or older 904 trans. Just need an adapter bushing in the end of the crank.
Problem is with using a 68 or newer trans with a 67 or older engine. That requires either enlarging the pilot hole in the crank shaft (I have had problems finding a shop to do that) or using a special built torque converter (small pilot nub, and large input shaft splines).

The plan is to drop a post ‘68 225 in my once 273 powered ‘64 Barracuda. I have an engine that was pulled out of (I think) 1970 or 1971 Dodge D-100. The seller believes the truck was originally a V8 … and the slant does not have the dipstick going directly into the oil pan which, base on what I have read, means this would have originally been a car engine? So, given that this was once a V8 car, which slant oil pans will fit the K and V8 steering components on the 64 a body? The consensus seems to be only a ‘62-66 a body slant pan IF the car was originally a six .. but being an original V8 car seems to open up more possibilities but also adds more confusion. The pan I have now (which may or may not be a truck pan.) is extremely deep (I believe toward the front of the engine, if memory serves … which isn’t always that reliable.). I can post a photo of the pan later if necessary, but I thought somebody might have done this (probably considered odd) swap into an early A body and might have sorted all this out before and might share their knowledge?

Post a picture of the slant 6 pan you have now or give us the 3 digit code that is stamped in the pan. That can help us to ID what you have. Greg

On the 64 Cuda, it doesn't make any difference if the car was born a slant six or a V-8 as far as the oil pan. The "K" members are the same. The only difference is the steering "drag" link. The V-8 car had a dropped drag link, and either drag link will work with the slant six. The problem with a slant in the 64-66 "A" bodies is you really need the 64-66 oil pan. There is one other pan that I understand works if you do some "hammer" modifications to the front corner of the sump to clear the "K" member. You also need the oil pickup tube to go with the pan. What transmission are you planning to use? There could be some issues, depending on the trans.

Good info from all here. Charlie meant to say that the Aspen/Volare pan (square bottom) is the one you need to just do a little hammer work and it should fit with the Slant 6 drag link. That pan uses the same pickup as a 67-76 Dart/Valiant pan. Easiest is to find a 62-66 pan and pickup, though. Lou

That is the 1971-1987 D series truck and B series van slant six oil pan. It absolutely will not work on a 64-66 A body car. The transmission issue is the torque converter hub diameter change that happened in 1968. If you are using a 1968-up 904, you are fine. You will have problems if you try mating the 70s era engine to a pre 1968 904 transmission, though.

If they are interchangeable it would make life easier in some situations. I would think "YES". I have never checked into that, but I have put the late front parts into the early trans and used a late converter. But by doing that you are limited to either using a stock converter or a custom converter (which most converter companies don't want to build). Also the input shaft is weaker, and it is harder to upgrade to more clutch plates.

Correction, the numbers indicate that my 225 is a 1971 model engine. I believe the 904 I have is a ‘72 or ‘73 model, so I am not expecting any issues joining the two. From what I am reading, it sounds as if the Volare/Aspen oil pan with an added dent is the way to go? I am reading (and finding) that ‘60-66 slant A pans are getting harder to find? I have not turned up anything so far, so if the Volare pans and pickups are both cheaper and easier to find, I’ll just focus my efforts on that. I also have (what should be) the correct length U joint style driveshaft and transmission yoke and I now have the correct early A motor mount brackets. All I (believe) I have outstanding is the oil pan/pickup and the early slant six valve cover with the “lines” stamped into it. The cover seems easy to locate.
