I started to assemble my 410" today!
I ran into a little snag this weekend. I started to put my pistons & rod in the motor, when I discovered that 2 rods won't fit on a common journal! I put in piston #1, no problem, then put in piston #2 and it rubs on #1 rod and won't go all the way down. It looks like there is too much radii on the edges of the rod journals. If I pull the bearings out the rods fit fine. So after a couple of phone calls today, I talked to Ryan @ Shady Dell and he said if you are using the Forged SCAT crank, you must use a race bearing, because they are narrower to fit the extra radii of the forged crank. Sure enough if you look up Clevite H series bearings in Summit Racing in the notes it says "narrow bearing". So I then called Coast High Performance and explained the problem and he knew right away that was a problem and would ship the proper bearings asap. So now I must sit and wait!!! I was hoping to have a completed motor by this coming weekend!
