I have a Pontiac 400 block that I had a friend "Epoxy UP" the Lifter Bores and I made
aluminum plugs for the Camshaft bores on the front and back of the block.
The oil dipstick location was used to get the crankcase suction pressure, and the
Pan had a stub section (3" diameter) where I could hook up my vacuum source.
The vacuum source was 8 Ametec 115923 Vacuum Motors.
I worked with Ricky Hunt on a similar flow bench (for the Butlers) before they purchased a Superflow
Bench for their shop. I did this years ago and it was written up in a couple of Jim Butler's early Catalogs.
So my block is used for multiple tasks: Flowbench, Mock-up engine for intake and exhaust fitment (turbo)
and Belt drive Supercharger Systems (Vortech Supercharger).
Well worth the effort.
