What are the best vehicles to find cast crank engines in...?

In ALL of the pile of Slant 6 engines I have accumulated over the years I have yet to come across a cast crank engine (determined by the web behind the water pump).

I’ve lost count of how many Slants I have. Almost all are forged crank 225s. I have just one 198 and still no 170s...

My garage has one from 1981 that you can have for free....!

Everything 1977 and later is cast crank and all are 225 ci. I don't know what you mean by the web behind the water pump. The forged crank blocks have a prominent casting number on the left side of the block which is absent on cast crank engines.

As has been said, any slant 77-up is a cast crank. Lots of them in trucks and vans from the 80s.

Give this guy a call:

The cast crank went through a weight reduction program during its life span. The early 1977 cast cranks have bob wrights nearly as large as a forged crank. The last year, 1987 cast crank is really spindly by comparison. This is based upon tearing down a ‘78 cast crank motor, an ‘83 cast crank motor and an ‘87 cast crank motor.

This detail is described in the article Slant Six Blocks by Doc.

I think cast cranks have been around way longer than 1978. It says right in the Bible, "Let he among us who is without sin cast the first crank"
yup they were phased in sometime within 1976 model year. a 76 engine could have come either way. Look at the stamped number on the block by the #1 cylinder behind the alternator. It will have an "E" in the line of numbers there if a cast crank.

That said, there will be a "running" cast crank slant, coming out of my '85 D150 later in the spring. I can go out in the garage right now, hook up the "-" to the battery and fire it right up. just under 100K original miles.

OOPS I messed up. I meant to hit "Quote" and hit "EDIT" instead. I wasnt wanting to change the post, just quote it then add to it in another reply box. Sorry about that. Brain fart.

I don't think that's accurate. Here's a picture of my cast crank block and the water pump pocket reinforcement is of the same tapered style as the forged crank engine Doc pictured. Sorry about the picture quality, but I'm still cleaning the block.

After reading that same description I used to wonder about that too. It helped me to think up and down thickness instead of side to side width.
The web on a forged crank block gets thicker and wider on the block end. The same web on a cast crank block gets wider but stays the same thickness.

Sure. I still think the casting number is easier to see.

Well then.... I s'pose I prolly do have a few then....

All these years I read that article to mean the thickness of the "gusset" as actually the width. Now that it's been pointed out I can see the more subtle increase in thickness of the rib...

Well,... At least I know my Poser status is secure still...

I just swung by the garage to meet some friends for some parts swappin'.....

Yep... several of them engines layin' back there got the thinner web thingy what don't get no thicker (not wider)...

I just gave one of 'em away. Hopefully it'll wind up in Dennis' old Duster... or somethin' else cool...
