Customer bought a man-o-war block that is 8.2 deck with Cleveland mains. Windsor pan rails and Windsor oil pump. Clearance for a large stroke.

Any idea on how to source a crankshaft?

I haven't seen the block yet and don't know all of the measurements, what needs to be done for that crank to work? Work to the crank is what I mean.

if you use a cleveland crank in one of those blocks you have to cut the front of the crank for the gear to fit, the Cleveland has a shoulder which moves the gear out. or have the windsor stroker crank cut down to cleveland mains....

Not sure whats out there now but the two forged cleveland cranks I bought back in the day both needed a spacer to use the cleveland timing chain. As far as I am aware the shoulder is the only difference other than the size of the main journals. dkp

Rollmaster already offers a timing set which fits that application.

eagle and I'm sure others do offer windsor cranks with strokes from 3.5-4.25 with the 2.750 cleveland main size.

Did not know that Randy Never needed to put a cleveland crank in a windsor block....I always just used a Cleveland block.....

Before all these companies came out with their version of a Windsor stroker crank, a 400 crank was popular because it used the bigger 3" main bearings like a Windsor; however, it also has the Cleveland front snout.

No luck on the crank deal. I have informed my customer to get rid of the block. According to the crank companies i contacted today, Cleveland cranks require too much machining to be worth the trouble and scat was the cheapest place at $1800 for a custom one. I wouldn't mind the 3.5 stroke but the crank throws will not clear with the 5.4 rods. This was a low horsepower deal with a single kit for grudge nights. I am trying to get him into a dart or Motorsport 9.5 or 9.2 block.

Tell your customer whatever you wish however, whoever you talked with about crankshafts doesn't know what they're talking about. A Cleveland crank drops right into that block.
5.4 rods ???

ALSO:
You can get a low cost 9000 series cast steel 2.750" main Cleveland crank from SCAT in either 3.85" or 4.00" stroke with 2.100" throws.
A 2.750" Cleveland main size 4340 forged Windsor crankshaft is available "out of the box" from Scat in either 3.50", 3.75", 3.85", 4.00", 4.100" or 4.250" strokes also having a 2.100" throw diameter.

Please check post number 1. 8.2 deck block.

Scat, probe, CHP, my engine builder, Bennett, Kuntz: that's my list who don't know what they are talking about I guess. lol!

I'll call tomorrow. I told the guy to pass on this block but he thought it was to good of a deal. With a 3.5 stroke it would be close to 380 cubic inches out of an 8.2 block. We really wanted a 3.25 or 3.4 stroke. I have never had to upsize the crank journal. We run 302 mains on our 9.2 deck cup blocks.

I guess I messed up on my math thinking a longer rod wouldn't work. Please correct me if my thinking was off.

8.2 deck
3.4 stroke
5.4 rod
~1.1 compression height

8.2 deck
3.5 stroke
5.4 rod
~1.05 compression height

Obviously dependent on a lot more factors such as gasket thickness and actuall rod used. Please, I am not a pro and do not claim to be in this department. I am an assembler who doesn't turn down much work. Lol

yes they do , a stock type 302 timing set . as said a stock Clev crank must be cut to W specs

other set is for W snouts in a Cleveland block

that's what I am trying to tell the guy. Nothing is drop in and run in this deal. in an SVO block or dart or the world products block with standard journals this is an easy deal.

My mistake ... I was reading this as NINE.2" deck not an 8.2" deck.
I didn't even realize that an 8.2" deck was available with Cleveland main bearing sizes.
