That was Bruce Sizemore's Pinto Pro stock car. It was a Ford 300.
Slant 6 stroker?

Mike said in post #7 that the stroker behaved like it had 324 cubes.....not that it had 324 cubes.....
Does not surprise me that it felt like 324....
People building engines do not pay enough attention to the rod/stroke ratio. The stock 225 is already low at 1.6.
Stroking the 225 & keeping the same rod will reduce the R/S ratio to lower than 1.6 & boost low/mid range tq, all else being equal.

24 years ago we did just that. offset grind the crank . I wasn't the engine builder so don't remember the specs.
It was the now defunked Mopar Engines West. The reason was the use of aluminum rods, blah,blah etc.
Why ? just for experimental reasons to see what can work.231 cid. $$$$$ to run a normal aspirated slant engine and put a 67 Dart into the low 12's. Most benefit was head work. Just something we wanted to do.
Unfortunately, the Slant has a staggered bore center. If it didn't, I'm pretty sure someone would have adapted something like a 2JZ head to fit.

As long as we are talking crazy deals, here is the Green Grenade dragster.

There were lots of stories in the old days about a Truck 240 Cu Inch slant.
Here is a blurb from a 1969 Hot Rod Engine Swap book.
A 240 would be a .110 overbore with a stock 4.125 stroke.
I have never seen any Mopar documentation of this engine.
Lots of the slant racers are doing that much overbore.

There was this floating around the Internet a few years back.
Supposedly a cut/weld job with 2 Gen 3 hemi heads... lots of speculation of whether it was real or not.
There's no speculation, it was sliced & diced 1st gen. heads epoxied together, it was rumored to have been started & failed quickly...photo-op over...
A 3.50" bore 4.50" stroke is a 260c.i. , that's the biggest Dutra ever did & didn't recommend it for anything more than a torquer street cruiser. The proximity of the cam tunnel etc. will limit how much bore over 3.50" can go, and how much extra crank throw can be had.

Port your own head with larger valves, build block for boost, put a turbo on it, drive anywhere and have fun.

Around the late 1980's Direct Connection had a stroker crank kit for the \6. The kit made a 242 CI. I was doing 2.2 stuff so I was not interested.
That's very interesting. I've never heard of such.
That engine ended up being a total internet hoax.
That would be a .020"-.030" over bore & 4.375" stroke, & not one catalog or book from Mopar shows or even mentions that, sounds like an independant setup from somebody.....a dealer or Mancini etc......

*4.375" stroke*
Piss poor Hot Rod Folklore, no such animal.
3.25" Bore ; 218c.i. '34-'54 , 230c.i. '41-'60 .
3.375" Bore ; 228c.i. & 241c.i. '37-'41
3.4375" Bore ; 237c.i. '42-'52 , 251c.i. '42-'68 , 265c.i. '53-'60 .
*These are all listed truck apps.*
All of which would be flathead engines.

May be right about not being a "P" part but I think it was listed in the Direct Connection monthly magazine. They said a fully ported head and Fuel Injection was in the works too. Some things are pipe dreams and never came to fruition.
DC/MP did offer a ported head, good pistons & a few decent cams, a windage tray & bolt package, intakes/carbs etc. all of the hotrod valvetrain stuff was just SB to go with the 1.70"/1.44" valves they sold. I think that would've been cool if they'd have offered one.

Dutra documented a stroker 225 build over on .org several years ago. The production cylinder, even ported to the max is still largely inadequate even for 225 cubic inches. So more demand for airflow makes the head even more inadequate.

Just swap in the amc designed 4.0 and have a far superior base to work from.
Maybe some wants a diesel like powerband
the reputation these motors have for durability and the amount of abuse they'll endure borders on myth, but can they make a respectable amount of power and hold together as well? asking for a friend....
funny you mention that...
