Yes sir, got the parts for a 470 build - Molnar 3.91 crank and 6.535 rods.... just seeing what combo's are available for a 4.15 stroker.....all I really came up with was the 440 Source 500" one. Seems odd (to me anyway) to go to the trouble of making a 4.15 stroke crank (especially for such a seemingly narrow market) and offer very limited rods/pistons that can be used with it? Thank you....
