Jon, why did you decide to paint versus powder coat? I painted my car's current engine -- needed to get it done and in the car -- 3 coats of hi temp paint, 4 coats of hi temp chemically resistive clear, one splash of gas when I was putting the car back together and the clear's streaked.
Looking good. That block is hardly hideous, though You should see the M106 right now. What a mess. Still haven't determined if I'll be able to fit the H1E in the same place as you, for the same reasons.
best, whit
