340 "the hard way"...318 w 3.55 crank...thoughts

I've always considered Crank WIDTH as the Centerline to the outside of the counterweights...IE 1/2 the crank Diameter.

I think we're talking the same language...just different "dailects" 8)

I think the 3.55 will be a good crank, the Aluminum rods are thicker on the small end and they have a clearance"cheek" which is roughly the same dim as the very bottom of the piston pin and that dimension is roughly 5.25" from the big end crank throw centerline....that's where my concern is. The dim from the B/E C/L to the bottom of the pin is 5.508". With 1/2 the stroke being 1.775" I think the factory CW (approx 3.625" from the CL) will clear but we can't be sure until we mock it up so I think some, but hopefully not much will need to be trimmed and possibly a chamfer will get us to .060" clear with out a lot of work.

Bobby, I gotta get the crank shipped to me from the west coast...if we can get something set up maybe I can just get him to ship it to your shop??? The Slugs and rods we can figure out how to get there....I'll be in Greenvilles SC for about 4 days next week (week of the 30th) , maybe we can meet up somewhere?

Originally, I was gonna put an 11:1 360 short from a buddy in it but it fell through, I figure since this is a 30K mile 318 roller block I might as well use it.

BTW, my name's Bobby too, some of the Moparts guys around here prolly know me.
