Just got this MFI it was in a friend of mines hot rod stash. He used to run this on. Cleveland headed junior fuel car. I don’t know much at all about these but would like to run this on my 56 Fairlane gasser. What all will I need? This thing looks pretty damned rough. The threads for fuel nozzles are pretty trashed. They have definitely been around. These appear to have been filled much like Cleveland heads were back in the good ol days. I guess I’m just looking for some direction. Thanks in advance. Look forward to hearing from guys in the know
Could be a good acquistion. It sounds like you are doing the necessary surveying before committing (metering block, pump, etc). No.1 for me would be verifying the potential port match with the heads you are planning to use, are you willing and able to fill and grind on either to get an acceptable match? Back in the day I bought an Enderle that was probably 3/16 off laterally from my previously ported heads
Tig or mig up , reshape ports to your needs , same with nozzle threads ( weld retap ) If was on Nitro you will need to change spool valve to gas or Alky , same with Nozzle sizes more likely, Go to Kinsler injection there catalog is also a tec manual for setting up & user guide for many type MFI's
I'd find a shop/company that is very familiar with MFI setups and bring the whole works to them. But, as another poster mentioned - FIRST make sure the dang things can be used with your heads. If they fit (or can be modified to correctly fit), then the rest is just typical MFI work --> pump setup, nozzle setup, barrel valve setup, bypass setups, etc.. You need to understand how all this stuff works and start out with an overly rich tune . . . then start leaning it out to get the setup where it needs to be. If it was my engine, I'd have the complete engine and MFI setup on a dyno - to get everything dialed in at a specific air density and temp. You'll need to lean on somebody to help you understand how to change the main pill to accommodate various changes in air density, temperature, altitude, etc.. Once you understand how MFI systems work - they are pretty easy to tune. Also, if you can run alky in whatever classes you plan to run in, that is a bonus - as the tuning window for alky is much bigger than gas and it is easier to tune/run with alky. Lastly, once you have it running and understand the tuning aspects of it, make sure you keep notes on the various places you run the car -- to record the air density, temp and overall weather conditions, etc - along with the tune, so you know what is needed in that environment (to at least get close the next time).
Looks like a Kinsler unit that somebody used on a raised port head. It's pretty rough. Did you get any other parts with it? Fuel pump, pump drive? All the extra parts will run up costs to put it back in service. What engine do you plan to put it on?
Plan to run on a Cleveland ford. It was on an svo Windsor block Cleveland iron heads in a dragster. I plan on on iron 4v heads too. Although I will run a Cleveland block. I will have to fab a new valley plate. I got the manifolds and barrel valve. That’s all
Fuel Injection enterprises is a good source. If it's a Kinsler unit, contact them. Both have (or used to) a bunch of info on their websites. I bought stuff from both. First order of business is finding a suitable sized pump. That will depend on what fuel you plan to use. All else will depend on that. It is possible to run an MFI system on the street if that is in your plan, but you will have to allow for quite a bit of fiddling to get it's part throttle manners to tolerable levels. And, get use to the fact it will use a bunch of fuel. I drove my OT street legal drag racer to a few car shows here in town. Mechanical injection, and turbocharged. Granted it was on methanol, but it took 5 gallons of fuel to make an eight mile round trip.....which for the most part was "Punch & Coast." In my mind, if you're gonna run mechanical injection, why not run methanol?
I would not of expected the ports to be raised on an iron head. Port floor filled and weld on the top side, but then the holes are all slotted too. Kinsler may of came that way with the slotted holes. I have a Pete Jackson unit for a Boss 302 and wanted to run A3 heads but I didn't want to hack up my Pete Jackson unit.
I had Kinsler go through my Hilborn unit one winter. They did an excellent job. It came back and worked perfectly right off the bat. I think I only had to adjust the idle.
I have no doubt Kinsler can go through and make this a runnable system again, but when I talked to them about my injected 4 cyl they said it will never work and didn't want to help me at all. That was 2 years ago and I have been driving it on the street most of last summer! It runs great! To the OP I suggest calling Kinsler to get what it will take to get this running on your Cleveland.
There should be a mfgr tag on it and serial number, send it back to whomever made it that'd be the best thing. The original mfgr will have a vested interest in it, you send an Enderle set back to Kinsler and you'll hear all mannor grumbles. I have Kinslers on one car and Enderle on another, both are very good for different reasons.
If it's set up for A3 heads - find a pair. You won't be disappointed. My 310" (destroked NASCAR 351 pillow block) TransAm engine is making 650 hp with a single 750 cfm Holley. I'd love to have your set-up. I've got a pair of Enderle 80-A pumps if you're interested.
I have been doing well. Sure miss the Meltdown Drags. Maybe with any luck I'll be back at a track next year.
A couple things come to mind - Methanol and epoxy don't play well together. Methanol will delaminate and erode epoxy over time. You can use a catalyst automotive clear over some epoxies to help protect it from the fuel. If its old epoxy it may be wise to remove and redo it. I don't recognize that particular casting, doesn't appear to be an Enderle or Hilborn, not sure if its an early Kinsler. I'm one of very few places that can build or modify Injectors. I make my own parts and the only guy in the country restoring Hilborn Injectors. Happy to help in any fashion needed. You can check out my Instagram 402bossman or bossfuelinjection.
