Exactly right, Ross. The cast crank wouldn’t make it. The narrow 2.438 journal size wouldn’t either. We found ways to make the FE journal live to 8500 when we had to, but even there, not those power levels. The 2-inch is size of choice for me. The 1.888 Honda at that power level won’t make many runs before service. There isn’t enough load bearing surface area at that power. The Honda is good at 800-900hp. The 2-inch is more durable past that. On the stroke, the piston speed would be a problem at 10K rpm. The stroke eventually becomes a parasite when you swing the mass faster and faster. Comp Eliminator guys have had success with a 4-inch stroke, so it is doable. You won’t find long strokes in Pro Stockers……They make the bore as big as possible, and plug in the stroke number to make 500 inches.
The 800 inch mountain motors don’t rpm like the 500 inch ones do.🙂
For most purposes the FE journal, or the normal 2.200 that is common to the stroker cranks is just fine. I’m doing a twin turbo 400 inch FE for myself. Not a super high revving engine. I prefer the 2.200 in this case, for the wide bearing and generally available “boost” tolerable shelf rods. We want to make 1000 hp below 6500 rpm with .550 max lift, so it can drive anywhere. Still debating draw through carbs with water-meth versus port injection with an intercooler. The latter will probably prevail, but the carbs would be much less complicated for a Holley carb guy. Okay….. am getting off the subject….
