Hot Rod Blog: Fuel Injection

The Inspiration

Road racers have individual injector stacks. It's a rule. So I need to do the same for my high-tech road racer themed hot rod. Check out these examples:

Whoa! Here's something I haven't seen in hot rod land. Makes me wonder...

Injector stacks on a Ferrari V8. Colors are nice too! Bit busy, though...


Oh man!

Stacks and Curvey Exhaust...

Jag-you-are Stacks!

Another thought I've had is to create a combination hidden air filter and cold air induction system. Picture a velocity stack intake mating with a cold air box. Mating surfaces can look something like these:

Billet base plate with trumpets...

Basically, a flat plate that the trumpets come through. The hood would have a cold air box that mates to this when you close it. An air filter would be hidden in the hood, and the box would take in air through a duct over top of the radiator. The base plate can also hide a lot of the injection and throttle linkage messy details, cleaning up the engine. It can also hide the air filter, so that when it's open, you don't realize the air is being filtered. It needs to be machined from billet so it looks good and has some interesting details machined into it.

Open the hood and this all goes up so you see the glorious trumpets, radiator, and engine. Close it, and it seals against the bottom plate. Seems to me that fits the High Tech Road Racer theme very very well!

The Perspiration

Towards these ends, I have acquired via eBay a Kinsler injection manifold to fit my block and heads for an amazing low low price. Check it out:

This thing is going to require some work, but Kinsler has done a lot of things to make it straightforward. For example, the injector bosses are machined to accept either mechanical injectors or EFI injectors of various kinds using a threaded adapter. So, we acquire the injectors, adapters, a set of velocity stacks, a couple of fuel rails, throttle linkage and position sensor, and we are in "bidness" as they say in Texas. This thing will look bitchin', but it'll be reasonably well behaved on the street. In fact, it will clean up the act of the over-the-top roller cam I'm likely to stuff into this mill so that it's actually tolerable on the street. The cost of all those accessories to finish the manifolds is pretty high--Kinsler quoted me not quite $2000 for all the goodies. They will assemble it for that, and practically insist they need to do so.

There is one fairly nasty fly in the ointment on these manifolds. The intake bolts do not line up with high port Cleveland heads. On those heads, the bolts are near the bottom of the ports (gee, maybe that's why they're "high" port). On these manifolds, the bolt holes are near the middle of the port. Curses to all those folks on the web that have "complete Cleveland intake manifold lists" and say these are the parts to fit C302B heads, because they don't! All is not lost, I can remachine the manifolds a bit, and get them to fit, but it's going to be a project. See below under "Perspiration, Part 2" for one alternative I've come up with.

Since its made of magnesium, it won't actually polish up. I have two choices--I can either chrome plate it, or I can have it powder coated. I'll have to think about which one will look better, but I lean towards the powder coating option. When all is said and done, it'll look a lot like this:

Now those are some kind of stacks!

Pirspiration, Part 2?

This is quite a deal I've found. I thought the Kinslers above were a sweet deal, but they just don't compare. While cruising eBay right after Christmas 2004, I always like to check newly listed items first. Take a look at what I found for just $400:

These Saleen manifolds are a cool sort of angle draft, which just looks more exotic, and gives a little better hood clearance. They also come complete with linkage, fuel rails, and all set up for EFI injectors, which is nice. Apparently there are not many sets out there. They were made up for the Saleen racing effort, so are pretty rare. So now I am the proud owner of not one but 2 sets of exotic fuel injection manifolds for the venerable Ford Cleveland, or close relatives thereof.

There's a third possibility too. A guy contacted me to let me know he is casting up Weber throttle body-style EFI's that will fit C302B's. They're pricey, but considering they're new, look sweet, and are built to fit the engine, are very reasonable. Gotta make a decision in January, 2005 which way to go.

Check it out, I may also use my machine tools to build an injection:
