Hilborn injected 65 Belvedere

Very, very nice Jon. I have to say that if the set-up was streetable I'd definitely want to go the same way. I know I could go the electronic route but then you're into some serious money. Awesome fella!!

Jem

Thankyou ( the car is actually rough close up )

It is a real shame about the fuel consumption because I did want this on the street but I think it is a no go. I have had to put a fuel tank in the engine bay to gravity feed the pump. Space has restricted the size which in turn restricts the fuel range. Also I could see me being in a layby filling the tank in the front and a gust of wind carrying off my bonnet. I have also had to put an electric water pump in and I just don`t think it would be reliable on the street.

Yeah, bummer that! From what I've read the only way to go outside of a race car is electronic but as I've said - serious money. But you've got the ultimate look as far as I'm concerned Jon!

Jon, I can't help you with the fuel consumption, but there is a way around the size of the tank. Back in the '80's, a mate of mine had a 4 hole Hilborn set up on top of a blower in his Camaro. He had a small tank up front to gravity feed the system, the tank was modified to take a pair of Holley float bowls. the float bowls were connected via an electric pump to a fuel cell in the boot. That way the front tank will be constantly topped up as required. He also had a remote starter switch under the bonnet so that he could prime the injectors and crank the motor over to start it on his own.

Thanks Blue

I did wonder that about a second fuel cell but wasn`t sure how to " control " the level in the front one. I`ll talk to you this weekend see if there`s something that can be done.

I didn`t make it clear .... once the engine is warm you don`t need to manually prime the stacks. That only needs doing when you start from cold so isn`t a major hassle. I have got hold of a horse syringe ( living in Norfolk has it`s advantages ) with a piece of tube on the end that I can suck fuel out of the cell, put the cap back on, prime the stacks and hop in the car before the fuel vapourises.

Seems to work

I wish I could find that old Hot Rod (or was it Car Craft?) article on how a guy modified one of these inductions to work on the street. It must have been in the mid-80s I think?

I seem to remember some sort of valve instead of or combined with the "pill". I know he ended up with a good air/fuel mixture all the way from idle to WOT as well as good part throttle mixture. Done right it shouldn't be any more thirsty than a big double pumper I would have thought?

Slightly different scenario I know, but when I was setting up my F/Inj (EFI) I was getting terrible fuel consumption.

I once did £40 of fuel traveling 1 x 6 mile return journey & half a dozen start ups/idling on the driveway

After numerous & god knows how many hours of tinkering, I now get about 10mpg driving sensibly.

I can easily get to low single digits if I allow the right foot to take control

With some further tuning, you should be able to improve upon your current consumption.

Mark your effective cubic capacity must be at least double that of this engine. If you can get 10mpg in that you are going very well indeed.

There was an article in one of the American mags in the '80's that I remember (might be the same one Dave is thinking of) where a guy was running a yellow pick up truck (Dodge?) on the street with Hillborn stacks. It was on alky though, I clearly remember it stating the fuel consumption was double what it would be on pump gas. There was a fuel system diagram, and I'm sure he had figured out how to get it to self start without manually priming it.

No you haven't. If you read the discussion we all agreed this is one race car that probably should be there at a classic show because of the true 60s styling. The "argument", if you want to call it that, was about having all or mostly race cars.

Don't remember it being a yellow truck. In fact I am sure the article was in B&W and it was petrol. But my brain is all mashed up so maybe that was it. Running Alky would double your fuel consumption anyway.

blue you are right alky mtr will use nearly double double that off a petrol mtr but the alky is peanuts pricewise so it actually becomes very cheap to use, i think jons mtr must be able to be tuned to get much better gas mileage very similar to a big carb

Dave, you've jogged my memory, I'm sure there's a B&W article in one of my Hot Rod year books with a guy running stacks on an otherwise stock looking Ford Falcon. I'll have a look tonight and see if I can find it. The other one I now remember was a '69 ish pro street D100 with a 340 in it.

Also, just found this,
