Message	I sent them a factory crank and block, and I modeled the rod journal and rod using pro engineer to determine the appropriate rod and journal width to allow for using the factory bearing without modifying it. I explored using different bearings from other engines for additional bearing width, but the tradeoffs were unacceptable. using L28 diesel bearings would provide additional width, but requires a really tight fillet radius which would seriously weaken the crank. For this reason, Crower refused to go smaller than 3/32" on the fillet radius to keep stress concentrations at a reasonable level.
Follow Ups	Billet Crower crank and rods group buy... anyone? - LitlElvis 13:36:24 04/05/14 Is this a stroker kit? If so, how much more displacement? (n/m) - MixManMash 14:37:33 04/05/14 Not a stoker. No need in my opinion. (n/m) - rcmadness 14:58:36 04/05/14 Agreed, stroker = overrated... Here are some other notes>>> - LitlElvis 15:23:48 04/05/14 the "stroker option" isn't as simple as it sounds - aliaZ 18:02:26 04/05/14 You designed the crank? (n/m) - ZXRider 21:18:49 04/05/14 yes, I intended on designing a stroker crank - aliaZ 22:35:08 04/05/14 Does that mean you work/worked for - ZXRider 13:33:51 04/06/14 I worked with crower on the design - aliaZ 15:31:55 04/06/14 Don can ProE calculate the torsional rate of the crank? - LitlElvis 11:10:20 04/07/14 not the version I had, but otherwise I'm sure it could - aliaZ 21:49:15 04/07/14 Wow that's really cool. Any chance you could - ZXRider 11:49:46 04/08/14 I no longer have the model, or pro engineer for that matter - aliaZ 14:01:56 04/08/14 Any idea what redline w/better springs & solid lifters? (n/m) - Turbodog (CT) 16:36:08 04/05/14 I guess I'm not looking at it as a way to extend the RPM - LitlElvis 23:00:05 04/06/14 Definitey like the strength & oiling improvements - Turbodog (CT) 09:49:19 04/07/14 Wow....no doubt! I bet that sure woke you up!!! (n/m) - The Hawk 08:56:11 04/09/14 FYI - if you send them your pistons and pins - aliaZ 17:24:47 04/05/14
