Re: [Amc-list] Wiring diagram for 4.0 head and EFI on 258? Or Clifford with 4 Bbl?

[Wrambler242@xxxxxxxxxxx]

Depends on how much you like to tune carbs.
I don't enjoy it much, so I converted to 91 injection off a Wrangler.
The difference is night and day.
Starts first time, evertime.
No pumping the throttle and feathering it while it warms up.
No hesitation, no bog, it just plain runs good.
I for one don't regret the effort at all.
Unfortuneatly I am not much of a compiler of info, so I can't easliy provide the needed info.
I spent more time doing it then needed.
I have been told I have one of the cleanest swap installs people have seen.
You can take a look at it and judge for yourself by going to Photobucket and looking up Wramber_242.
