Just for interest, here is a Hilborn catalog page from the late 60's.

Look what they offer under 'other models available...!

Can't see it very well, but looks like I can get a set up for $200?? If so I will take 3 sets. :D :D

Sorry, that's the best pic I have! I'd take a couple, too!

I bet they sold a handful only, ever.

There is a dragster or two (shown on this site in other ) with a Hilborn setup on it. I think I've seen one or two others cars with it. But never in person.

If you look at these injectors, even today, it's amazing the quality of design and workmanship in them. You can see a great deal of thought went into them, and the quality of the machining and casting is very, very good. You can be sure no computers were involved, either! It's interesting to see how the automotive aftermarket has always had such a wide array of companies....some produce junk, some sell good stuff, and some produce scary-good stuff.

I read it as $260, and that includes the pump. :shock: Either way, I'm with Rick.....send me about three setups.

I seem to recall a discussion on the board some years back about these. Somebody sent a query to Offenhauser as to the possibility of getting some more manifolds cast up. As I recall, their reply was in the neighborhood of $1000 each, minimum of 20 orders, and it would be an unfinished casting. The buyer(s) would have to do all the finish machine work. On top of that, there was all the other small parts to make it functional. Pump, nozzles, barrel valve, hoses, stacks, etc.

For a Slant Six, it would not be too tough to make your own. Or rather, it's one of the easier engines that you could tackle. It'd be even easier if you bought, say, a set of BMW (inline 6) throttle plates and adapted them to the Slant head.

For example, here is a very nice set for $300 on Ebay right now. The port shape is not the greatest match so maybe it would pay to look around for a Toyota or other make that had a better match. But in any case, there is a lot of good engineering and machining and parts all for $300.

I just bought a CNC mill...if I can figure out how to run it, this is just the sort of project that would be fun!

$260 plus $12 for the ram tubes. $272 in 1965 dollars is right about $2200 today. Seems about right. Full factory retail for a new AFB to fit a 273 was $49.50.

Glorious, Mark.

FWIW, I am currently working on an individual runner EFI system...

Greg; That's actually my pic, and I'm quite sure I posted it on the "old" board a number of years ago.
It doesn't surprise me that it might have "traveled around" some.

Thank Roger, I appreciate knowing whose it is!

Here's my guess.....Hilborn produced these in 1969, one time, and that was it. I'm guessing they made less than 2 dozen.

It's also interesting that by 1969 the 225 was very well established but they still designate this the '170' model.

When I sold the Grenade I kept wheels, engine and transmission, Moon tank and pedal.

Are you using Hilborn parts from the catalog?
GregCon
What is the highest intake production number you have found?

I sold the front cover that came with the engine that had injector to a fellow on the west coast. He has a Hilborn slant 6 plus the Dragmaster dragster injection that used Hilborn parts. I can’t remember the number on his intake.

Mark,

I am using a weber 3X2 setup with gutted 40 mm carbs and pico injectors in the runners, driven by megasquirt computer. Should be fun...

Actually, the back story is that sometime during the 60's, a young, up-and-coming engine builder took a contract to build a 170 for a salt flats car. After deciding that the factory induction system was never going to be good enough to be competitive on the salt, he contacted Hilborn. Hilborn knew who they were talking to, and basically told him, we'll get back to you. When they did, they had a full setup figured out, and Kieth Black was able to complete his contract, and help field what I believe was a successful car. (I have no proof, but I suspect this was Wilford Day's car.)

When I was in my early/mid 20's, selling auto parts in the early 80's, I started hearing about the Hilborn system, and thought it was all bullshirt. After all, it was the 60's and everybody was doing big inch V-8's. As I heard more details, one at a time, over a few years, it all started making sense, as salt cars are mostly inch/weight for their class. I had started keeping an ear open, hoping to someday find one. Somewhere, I heard the Kieth Black story, and decided to dig up his phone number and give him a call. Got lucky enough to actually talk to Mr. Black himself, and he remembered the engine and car, but was sorry to say, he had nothing collecting dust in a corner. (I had to try.) This did, however, confirm what I still thought of as a fable, or old racer's tale. Took me 21 years of keeping an eye open, but one finally showed up as an afterthought, in a local credit union swap sheet. Last line in the ad, after some Little Tykes outdoor kids play stuff, was the listing for a slant 6 Hilborn setup.
No, it didn't take me very long at all to make that phone call. Came away with everything but the pump and main feed and return hoses for a (relative) song.

It'd be great to combine it with an ally block and billet head, but the head gasket would never hold up against high compression in a drag race motor.
Wouldn't that be an eye catcher, all polished, setting in "somebody's" digger?
