I have a 67 Ranger with a 3 spd and a I-6, I have a 302 w/AOD that I would like to put in for better highway drivability and gas mileage. I have done motor swaps on other vehicles in the past but I just want to be sure I am not forgetting or overlooking anything. A bit more info- manual drums all around long bed. I also at some point plan to install power disc's in front but that is not pressing as the drums work fine. Once I get the feed back on what to think about I will then move to whichever forum is the best one to be in for this conversion.
I think the suspension should be fine as the weight difference is not extreme, so am I missing something?
Thanks ya'll

Re: Point me in the right location
Howdy!
My experience is mainly with 460s and C6s. If I understand your question, you want to improve fuel economy in your '67 F100 Ranger that currently has an I6/3 speed manual tranny. If your main goal is MPG I doubt you will do any better with a 302. From what others have claimed on this site, the I6 and manual tranny does much better on fuel economy than any other combo if you're tuning for MPG. IIRC, guys are saying they get upwards of 15 MPG with an I6, which I can believe as I'm struggling to approach 10 MPG in my '68 F100 with a 460.
Take care,
Joe

Re: Point me in the right location
I might be off on my figures but my 54 Sedan with a 302/AOD combo got me from OKC to the Oklahoma Arkansas border before I needed to gas up and that was with a 4.11 rear end. So I am hoping that with an AOD and 302 setup I should be able to get better highway mpg's. Pretty sure this rear end is not a 4.11 as it can run at 70 on the highway, just when I do I will eat up 3/4 of a tank making a 100 round trip. That is fairly sad IMO.
