Going to 3.75 stroke and a Honda bearing.  Thought I would go this route instead of Billet.

I went  3.60 with a 292 crank, and used a 1.850 bearing (CB 1664 H), no welding

Think i read somewhere that going under sizing can cause oiling issues. the galleys are cut on an angle and will move to outer edge or center depending on direction their in. not sure if this is an issue for y blocks or it was for something else but something welding can overcome. If Your welding them why go down to honda bearing, would think you could leave it a little larger to give strength and room to undersize in future rebuilds

SBC 2.000” and Honda 1.889” (and smaller) journals helps with the connecting rod to camshaft clearance issues that comes from increasing the stroke in the Ford Y engines.  I routinely do the Y crankshafts so that they use the 2.000” journals for a 3.600”-3.625" stroke and for strokes greater than this, I will use a Honda journal.  I have used the Honda journal for strokes up to 4.250" and 4.300” but those particular strokes does require a connecting rod with an angled parting line.  Up to a 4.000” stroke simply requires a conventional designed connecting rod that fits the Honda journal.

Here's some history.  Ford had issues with that rod to cam clearance when the stroke increased from 3.1” to 3.3” which necessitated making the camshaft journals smaller for the 272 and 292 engines.  Then again the clearance problem reared its head again when the stroke was increased to 3.44” for the 312 engines which necessitated a revised connecting rod with a shorter bolt rather than making the camshaft journals even smaller.

It’s been a number of years since I have seen a welded crankshaft in the shop.  With the aftermarket stepping up with readymade stroker and replacement crankshafts for the mainstream engines, welding up crankshafts has gone to the wayside.  The Ford Y is obviously not a mainstream engine.

Royce. You will need to keep us posted as to how your crankshaft works.

Ted  I think you remember Adney Brown form Engine masters?   I asked him to do the welding but he refereed me to an ex employee who basically does nothing but welded cranks,  mainly for tractor pullers.  He does a lot of Farmall M cranks.. He takes them from 5.25 inches to 7 inches. Mine is going from 3.3 to 3.75.. I am shooting for 550 horse.  My current 333 is about maxed at 490-500

Cast or steel crankshaft?

As a general rule, welding to increase the stroke is typically performed on steel crankshafts.  Welding on cast cranks has been iffy at best even when performed as a simple repair for a street driven vehicle.  The 292 steel truck crankshafts would be good candidates for welding.

Final results on the welded stroker..  yes, it was a steel truck crank.  Now for the rest of the build...

Nice, if you don't mind roughly how much did it cost to get done?
