I'm interested in fuel injecting my slant six valiant but im not exactly sure where to start. Are there kits made or a guide that i can follow that has a reputable performance/efficiency?

Thanks,

Aaron

Its more of a loaded question then you think....

No bolt on kits. You can go 2 ways, try to adapt a factory EFI setup from another engine, or roll your own by aftermarket ECUs. These come in several flavors from something like the megasquirt - www.msefi.com to the more exotic like the Accel boxes.

Read the megamanual at the link I gave, will give you plenty of info, much of it generic to EFI as a whole then just that particular ECU. Also check the articles section of this site, a forum member posted a pretty detailed chronicle of a GM system setup on his slant.

This is an enormous job, full of many interesting, and rewarding challenges. It will cost alot, and take a long time to complete. And after that you will spend many hours tuning it. But,your engine will run better, and get better mileage after you are done. Plus, you will learn tons from the project. You will understand every new car better, and not feel mystified by the magic boxes under the hood.

I agree with Pierre. Go read the Mega Manual. I printed it out, and it became daily bed time reading for me for almost a year. The completeness of their dicumentation is priceless. I can think of nowhere else where there is that much info in one spot.

If you really want to learn about this in a step-by-step way, you might take Dart 270's path: He started with a Holley Projection kit. It is old tehnology, and not very flexible, but his car ran pretty well with it. It is a complete, universal kit, needing only an adapter for the TB. Once he got it running the best it would run, and understood this set-up, he replaced the ECU with a Mega Squirt one. Then after he got that working, he replaced( or is in the process of replacing) the Throttle Body (TB) with a fuel rail and individual (Multi Point) injectors. In this way he learned about it a little at a time, and the car was never down for any too long a period of time. It's not the cheapest way to go, but it was straight forward, and a good, logical education.

Lou has three of these cars, all in various states of development, so this formula may not apply literally to any single one of them, but the basic idea is there, and I think maybe his '64 followed this path pretty much the way I outlined it.

If you need a kit to EFI your car you will not be happy with the result. It requires a lot of tuning to get it right. The skills involved n tuning are as complex as the fabricating skills.

If you want to TBI you need the following items:

A 4 barrel manifold and adapter to install a throttle body (OFFY with Turbo City adapter and Rochester 220)....less than $100 in my case

A ECU and laptop ( Mega squirt is prolly the easiest)....about $500 in my case

A fuel system: fuel pump , return line.....another $200

Wiring harness: harness, senders, relays ignition system . ...another $200

This is my plan for the winter on my slant. I have already done 2 SBC s sucessfully and have about 350000 miles on previous coversions.....they are never fully tuned.

I plan on posting an informal guide ala my Ford 8.8 swap.
