Ran into a small issue during the dummy fit. Whomever rebuilt the block when doing the 20thou over build screwed up.
Normally during a 393 build the pistons stick out of the bore 5 thou. One side of mine is stick out 5 thou and the other side sticks out 15 thou.
The blocks being decked to square and the pistons are having 15 thou machined off the crowns. Just as well, I have a piston with a 10cc dish
Least I probably won't have to deck the heads
Camshaft choice has also changed as a smaller one made more torque.
Hopefully I can get it back this week and screw what I need to screw together ready for the engine dyno.
