Cam to crank
« on: October 13, 2015, 05:37:13 PM »
What is the cam to crank center-line distance on an FE?   Does the 4.375 stroker crank cause any interference issues?

Depending on your rod selection it can put some rod bolts into the back four cam lobes.  Same for aftermarket blocks below the cam tunnel and windage trays.  It works fine - just a little more effort that the comparative "sweetheart" 4.250 combo.

My 504 has a 4.375 crank with 2.200 rod journals. The cam has .375 lobe lift. Rods are Scat 6.7 I-beams. I can barely get a .025 feeler gauge between the hip of the rod and #7 exhaust lobe. It all just happened to work together without any grinding. But I think if I started playing with cam timing that I might run into clearance issues.

Is there a certain type or brand of rod that lends itself to having more room in the problem area? Maybe use a cam with smaller base circle? Thanks
