48mm IDA intake vs Hilborn fuel injection on 58mm weber intake
On the left is a new blue thunder 48mm IDA intake, with a 10 degree canted mount angle.
On the right is a 1960's Hilborn Fuel injection system for a ford 427 with High Riser heads. The system consisted of two pieces, two banks of 4 throttle bores, of 2 7/16" (62mm) diameter, that are bolted to the top of the intake. I believe the intake has the 58mm weber bolt pattern and spacing. As you can see, the throttle bores are straight up, not canted at all. A somewhat rare intake. It has been polished, and no identification marks are visable. This should make alot of top end power. I unbolted one of the fuel injection throttle body castings to expose the mating surface of the intake.
As you compare the two intakes, you can see the larger bolt pattern of the 58mm weber intake, as well as the larger ports. There isn't enough of material on a 48IDA intake to redrill for a 58mm pattern.

Weber 48 IDA kit for 302 SB Ford closer
The manifold is just flat, no runners, tunnels, or fancy stuff. The carb barrels go straight down to the heads.
