EFI in '77 Chrysler Newport

[Rick T]

Our family pet c-body Chrysler "Thelma" (named after Thelma Houston) was the recipient of a Holley Sniper EFI setup on top her 400ci engine last summer. I had been fighting with the Thermoquad (and even a rebuilt Thermoquad) for too many years - I'd had enough. Of course the upgrade led me to replace the starter, blast and paint the manifold and replace the rocker cover and pan seals. It was a fun little project and I recommend it. That omnipresent kick-down choke and cough are gone and now I don't fear pulling out into traffic and feathering the accelerator from a light or muggy days are no longer anxieties. Life for Thelma is better and I driver her more. She's sleeping for the winter but in the season my wife even takes her to work and the kids enjoy rides in her. The EFI install saved our relationship.

Well… I finally got around to it.

Update on my 440. Pulled the engine redid it from top to bottom. I’m still using the Holley sniper EFI. We are thinking it’s pushing 580 to 600 horse. I’ll know for sure this spring when we put it on the DYNOTUNE.

Any lessons learned about your conversion we should know about?

In my situation and several others, I believe it’s best to turn the learning mode off, set up all your parameters, put it on a DYNOTUNE and then leave it alone.

Congratulations on your install and related experiences.
I'm temped to buy yet again a NYB just to FI it, lol.

I've thought about this for my Coronet. The Imperial runs great bone-stock, and I really don't want to alter a one-of-514 ragtop. The Coronet, I've owned since 1980 and will probably die with it. So, modding that doesn't really bother me all that much.

I am the third owner. The original owner pulled the engine, had it built put headers, etc. When I got it, I put the EFI on it, because the carburetor was junk.I then decided to redo the whole engine. My car was worth the cost and work of the EFI.
