At the original Super Cel a decade ago, I met a guy who stuffed a 300 straight 6 cyl under the hood of an EB. Of course he had a body lift among other major modifications. Does anyone know the guy I’m talking about?

I remember a lot of talk about it way back when. I’m sure those look better memories will be able to come up with names and details.

I bet it was the guy that had a write up on Bronco Fix. Sadly Bronco Fix is no longer around.

If I knew how to attach pdf here I could send a write up from Bronco Driver magazine by Jack Hagey and his 300 install in Bronco. Has pictures. I could email it.

I am a big fan of the 300 and it was the first option I considered to replace my 200 but it looked like too big a project for me. But what a great motor it could be in an early Bronco! The low end torque combined with a 4R70W would have been the ultimate drivetrain in my opinion. Back in 2010 I did not find much info on this upgrade so just went with the 250.

I helped with a 300 install into an EB about 12 or 13 years ago. By helped I mean I did all the wiring to integrate the factory Ford EFI system. It worked great. Fitment was tight.

I wonder what benefit you’d gain from changing where the 4R70W shift points were?
Remember that the 302 almost always had more torque than the 300, but the RPM range was where the big difference was.
The 300 might be peaking anywhere from 1800 to, what? 2500? The 302 was probably 2800 to 3200 or thereabouts?
For the general low performance versions anyway. Those are just guesses though. Don’t really have the info in front of me.
Sure would be interesting to drive one behind an automatic like that.

I owned a '66 Econoline long body for a couple of years. It was born with the 240/C4/3.0:1 9" combo in it, but when I got it the 240 had a dead hole. I had a 300 rebuilt stock but balanced and swapped it in. With the stock carb it got 10 mpg. Unless I was towing the avatar, then it got 11. It took a serious grade before you felt it, and I don't recall it down-shifting very often.

Sorry, urban legend, 300 gets you 260ftlbs, 302 can get you 300ftlbs

The peak number isn't the whole story, what RPM it occurs at is of equal importance.

With it's longer stroke than a 302, it is reasonable to think that comparable builds would result in the 300 developing more torque at lower RPM. The problem is that good heads are now easy for the 302 and there's not a heck of lot for the 300. That will inhibit the 300 in performing at it's best possible for any given build level.
