I just finished installing the Ultradyne solid roller cam and the new Butler Pro Billet Timing Set, Billet Gears 9 Keyway Crank Sprocket .005 Short. Since the engine was line honed the standard timing set was way too loose. The .005 short set fit perfectly.

Since I'm not using a mechanical fuel pump I wanted to get rid of the eccentric assembly. I used the Butler Timing Chain Gear Retaining Washer/Spacer. This is a clean way to eliminate un-needed hardware.

The cam is the same one I used in the 455 engine. I was happy with the performance with that cam so there was no reason to change. The only difference is the 455 engine had Harland Sharp 1.5 rockers and I am going with 1.65 Crowers on this build. Cam specs are Master Lobes R44/R41, 264/268 @ .050 176/187 @ .200, .3944/.3944 Lobe Lift, LSA 108. Bullet Cams suggested I install it at 106 but it came in at 107 and the timing gear set is adjustable in 2 degree increments so I am happy with 107. The 455 engine had the Doug Herbert made in the USA solid lifters and they held up for many years of racing and are still in excellent condition. But to be on the safe side I bought a new set, also the Doug Herberts.
