Couple more fail points and then some interesting and positive developments
Rear brake lines designed to fit 68-72 Chevelle...fell a little short. My ARP bolts are fine thread and the balancer on my BBC is course threaded...fail
Followed by some good news... when I mocked the driveline up the first time we ended up raising the trans 2.5" to get an approximate drive line angle. When the truck went back together this last time the angles and the numbers seamed out of wack so I ditched the 2.5" riser block.
Today I put the blocks back in the trans mount and viola.... all my little fitment issues went away. Steering column clears, the recess for the passenger side valve cover slides in and out easily, room to get at the distributor.
With enough room for my scoop to fit with some minor trimming of the rear carb mount... Win!
