New 400 Vacuum question
I got my new 400 in and going i let the guy that built it swap it in and i was just wondering if he had it hooked up right:
pcv to back of carb
c6trans to tree on manifold
brakes to tree on manifold
stock DS2 dist to pass front of carb
edel 1411 750cfm carb
pcv to back of carb

Those should work, although typically the PCV valve is hooked to the front center of the carb and not the back. The front center already has a 3/8" beaded hose barb while the connection on the back is just a threaded plug. They're both manifold vacuum sources so I don't see why there'd be a difference, I'm just explaining what Edelbrock recommends. The smaller port on the passenger side sits higher than the one on the driver side which lets you know it's ported, or timed vacuum which typically runs to the distributor. Sounds like he's got it right. Make sure you plug any unused vacuum ports.
