The Stovebolt Site Forums The Shop Area Engine Shop F.I. FOR 235 & H.E.I. CONVERSION

before i get into topic my head is still spinning from the quick and valid info response. who has any info on F.I. and H.E.I. FOR 235? fabrication is not a problem.anyone got pic's of such a conversion. someone has to of attempted such a thing because we all get tired of leaky,dried out carburator gaskets or that stuck float.i realize that simple is great(carb)but call me crazy since putting 80,000+ miles on my 4.0 f.i. 98' grand cherokee it's convinced me f.i. would be nice on my 52 3100 panel.thanks again for any and all response.

I'm sure an easy bolt on throttle body fuel injected "carb" kit could be made to fit on the stock intake manifold with minimum hassle. All you would need would be a timing input, water temp input, air flow input, and throttle postion input.
I owned a 91 Geo Metro once and this car had the simplest one barrel throttle body injection system on it. In the 200K miles I put on this car, I never had a problem with the fuel system or any sensors.
If a big company like Holley was shown enough interest, maybe something could happen.....

Holley markets a throttle-body injection system called Pro-Jection. It's pretty pricey, and performs best at full throttle. I'd be prone to think it would be simpler to grab a GM wiring diagram, and work on adapting a throttle body injection system from a 2.8 or a 4.3 Liter V-6 to a stovebolt engine. A few sensors and some wiring, and it wouldn't be too difficult to set up. The HEI distributor from the V-6 would need to be adapted to the inline engine to trigger the injection pulses for the computer.

Edit: Here's a tech article on installing a ProJection unit on a Jeep I-6, and it seems they're pretty pleased with it.

Fuel injection is nice on new cars because the carbs were getting way to complex. I don't see a need for FI on an old truck. When I bought my 04, Harley, Superglide, I INSISTED on a carb. Unfortunately the new Superglides are ALL FI.

I like simple things that work well and I like having control over my cold fuel mixture with the choke. Part of the fun of having an old truck is using the choke.

Yep, and we need to arm our troops with bows and arrows, instead of those newfangled 'flintlocks"! There's something to be said for new technology, especially with gas at $2.50 a gallon!

You can buy a new HEI for the stovebolt 6 for around $150. They even have a special round coil to appease the purists amoung us.
Check with Langdon's Stovebolt Engine Co.

I saw an article in a mag. a few years ago where a guy put a T.B.I. unit from a 3.8 buick V6 on a 235 but dont recall the details

that would be a good choice since the buick is a 231.

GMCpanel, it seems the site you linked to is no longer in business. It now links to a worthless search engine.

My bad...

I'm just going to try and revitalize this topic. Has anyone here done this? I had a conversation with my cousin today. He just coverted his old MG to F.I. Used "megasquirt". He said it was relatively easy and cheap. He spent just over $800.00 and has the tools and skills to build custom intake manifolds. I'm building a 261 stroker and am stongly considering this.
