I have a 454 going into my 71. I had a Holley 4bbl projection system but my computer went bad. Holley discontinued making the computer for my system. No replacement. I want to keep it fuel injected, but the new systems aren't "cheap". I want something simple. Who's running what?

I was running the same system on my Big Block and it just stopped firing the fuel injectors one day while I was cruising down the road. I switched over to an Edelbrock 750 CFM carb and never looked back. I didn't notice any power loss, but it is probably a little small if you're going for all out power.

I have a FAST system on my camaro. You will love the wide band 02 data.
There will be some interesting products coming from them in the near future.
Doug.

Go to http://www.jimsperformance.com/ and Email Jim. I can't for sure but I think he can help you get what you already have working again.

justanother71,

Holleys new ecu can run MEFI or TBI. You could use the new ECU but probably will have to upgrade to new sensors such as O2 and TPS..

Why don't you check over at http://www.chevytalk.com/ click on Forums and scroll down to the EFI / Fuel Injection Controls section and ask there. Doug Flynn who works for Holley and helped design their EFI sytems is the moderator there and posts regularly. A great guy whos always been very helpful; also runs a BBC Nova with twin TBI for air valves, MEFI on a modified tunnel ram . Way cool!
