Default Hilborn injection for big Cad?

I like the look of the old Hilborn injection units, and would love to run one on a 500-inch Cad. Now, I've read that you can adapt a 460 Ford intake to a Caddy, and I was wondering if there are any Hilborn units out there that would lend themselves to such a swap. I've done some online research and talked with the folks at Hilborn as well, but haven't come up with too much yet. I know Hilborn is currently making a 427 Ford setup, but don't know if that is at all similar to the 460 engine series.

flo,

You mean the type with 8 individual stack type throttle bodies? If so, it seems to me that an intake for hilborn should be fairly easy to fab.

Either two head plate/flanges, or a one piece pan with a valley cover.
Steel if weight isn't an issue, or alum if it is.

Since the Maybe use a mandrel bend, or part of one on each port, expanded/transitioned out to match the caddy head flange. Flanges on each runner to accept the throttle bodies, injector bungs if required, and so on. The bolt holes would need a raised lump with the proper angle spot faced for the bolts, but it should not be a big deal. Washers could be epoxied in place there at the proper angle, or a lump of welded in mat'l could be faced off at the proper angle.

Dave,

Yep, that's the type of injector setup I'm talking about. I don't have any fab experience (and hardly any welding experience period), but it sounds like you're somewhat familiar with it. Any idea what the cost for a custom build like that would run me as just a ballpark figure? Thanks for the help.

Default injection hardware

This pic of the tunnel ram I'm building might give you some ideas. it wouldn't be too tough to weld a flange or a transition piece to the stubs comming out of the intake flange. I made the stubs, with the intention of welding mandrel bent 45 deg. tubes to them, because I fabbed up a swedge to match the intake flange, and couldn't figure a way to hold the bent tube to swedge the end. I started with the stubs at 4 in. long, but will cut them shorter to properly space the vertical tubes side to side.
I want to try this manifold with a single "flying toilet"injector, but 2 rows of "hilborn's"would look sweet, and are not impossible to find in the circle track world. also in the R & D dream is a twin To-4 turbo set up with 2 'toilets, but this could be done with stacks also.
This manifold will start out in a FED, nostailgia digger, so the "period" look is important, and I 'm not smart enough yet to play with EFI and the turbos, all my injection experiance has been "mechanical" so I'm gonna start with what I know... RED

flo,

Wild guess;

Bar stock for head plates - $30. Lots of labor drilling/cutting port openings. $25 each for four 2"-2.25" "U" bends from Bassani or Burns Stainless. Hack them and get 2 cylinders per bend. Throttle body flanges could be cut from alum plate.

A metal shop with computer controlled cutting equip could cut the flanges with a few minutes programing and a few minutes cutting time. Unless you have a friendly shop, it'd sting though.

Several hours to a couple of days fitting/welding.

Afaik, the stock tin pan can be used with such an intake. Would need to get crafty on the ends. Perhaps plates to hold the ends of the pan down, with small machine threads tapped into the block end rails?
