Not much play time over the weekend. Rain, but clearing today so hopefully paint the block tomorrow. Need to get Number One Son's VL off to get the turbo piping done, and I'm on the road for work later in the week.
Got the balancer (ATI 916970) and hub dummy assembled to finger tight. The balancer needs to be SFI-rated to meet the IHRA requirements, and this one is (the Ross balancers are too, the Powerbond factory replacement ones are not). I won't need the v-belt groove in the hub, but it's not hurting anything for now.
The ATI balancer is fancy, and made me go back and download the instructions for reading. One bolt of the nine is offset, so the hub and balancer only go together one way. Fasteners get torqued to 120ftlb, and use Torx-plus fasteners. Glad I read the instructions for once, as it has a warning very similar to "These are Torx-plus fasteners. Do not use a Torx bit ya idjit. They will drive in OK to 120ftlb, but you will round the fastener heads off and they will NEVER come out again". Put the Torx bit back in the shed and ordered a Torx-plus bit. Dummied up the blower gilmer pulley and ordered some ARP bolts to mount them. The pulley is an old, abused, multidrilled piece that is OK for mock-up but methinks I best replace before driving the Norman in anger.

Will post some of the Repco head stuff over on that thread.
