Just phenomenal work. Belongs to a dude named Will who made the intake himself. He's running a Megasquirt. I can barely see the crank trigger wheel sticking out. I don't think I've ever seen that distributor before?
Would love to see and know more on this engine set up. One other thing that jumps out at me is the water pump is the reverse rotation version of the Edelbrock short style BBC pump. I would love to see inside the intake manifold to see if it was done with an equalizing diffuser . Kinda divides the plenum top to bottom forcing incoming air to go through a radiused opening allowing each port runner to get an equal feed of boosted flow. Even if this manifold does not have that provision I like it a ton. Hope to have one similar on mine eventually and to run boost.
