I had same problem with my ultra hp 950dbl pmp.I run a 434 with a solid roller on a 108.I run vacuum canister,and I drilled & tapped intake manifold just below rear bowl.I use a supervictor,& it looks like it was made with my custom port.(he,he)Had no choice,car is second gen. Camaro,no hood clearance.I had to run a tee with one large opening (power brakes)&one small(modulator valve THD350).Anyways,no issues looks & works great.
