I was at Pat Musi's shop in NJ on Tuesday to pick up a block and forgot my
On his bench was a billet BBC with 5.3something bore centers and a 13" deck that's going to be a 900" nitrous motor.
The block had a 80 or 88mm cam tunnel and the lifters have wheels bigger than the lifter bushing bore. The lifters are inserted into the bushings 2 at a time into the bottom of the lifter bushings and then the lifter bushings are bolted into the block. I didn't ask how they are keeping them from rocking/moving around. Should have.
The lifter valley is sealed off from the intake but not like the usual valley pan. Where the push rods come up through the block is a separate billet piece that's bolted onto the block on both sides of the valley. This narrows up the valley and a 5" (?) wide cover will seal off the valley.
He's running either a 840 or 860" motor now.
I asked when they will be at 1,000 cu in and he said "it won't be long".
