S/B stroker Cranks, All the same forgings? - 02/28/09 12:14 AM

Well I'm feeling inquisitive today, do Scat, callies, K1 use the same forgings & machine them to their own spec? If so what is hp rating with this forging? I'm thinking about going to a larger stroke( K1) with my turbo project & abandoning the billet 180* crank project..

In the 4" stroke MP has a cast steel so it is stronger than a cast iron piece and they have the forged steel is rated at a higher HP
ie} both are steel as apossed to a cast iron type.
I have no idea who makes them for MP so this is proberly of no help to you

i know of one turbo motor making over 1000 HP, actually closer to 1100 with a K1 crank. so far, so good.

Thanks Dan

Being that my block is a short deck I can't go crazy on stroke but with my 1.125 c/h JE's & a really short rod.....

340 mains 9" deck. A 4.125 will fit with 5.81 rods. Comes out to a 1.40 rod ratio I think... or how about a 4.250 with a 5.750 rod... my parts collection for this engine is a 3.375 stroke crank with 6.200 rods with a 2.0 pin
