How's this for some tall gearing?

[Ecky]

I'd personally like to see something similar, but scaled down. 310lbs / 140kg dry is quite a bit.

For comparison, my car's stock gearbox was 67lbs, and the 6 speed I have in it now (which can typically handle up to 400hp) weighs around 90lbs. That 310lbs is actually not all that much less than the complete Honda 2.4L engine and transmission.

I'm not really building the TR7 for mileage. It's more of a go fast fun car. I still want decent mileage on the highway. If I can get high 20's I'd be happy for having a V8. I'm hoping that with the lighter weight and lower stock profile (about 50") and tall gearing I'll do better than that. 26 mpg/highway would be a 360 mile tank. Almost 5 hours on the interstate. I just didn't want a super high hp build and only high teens for mpg.

Thought about a GM LTG 2.0T but not sure it will fit under the hood. Supposedly 27"-28" tall. Not a lot of vertical clearance. I have heard that a 1UZ-FE Toyota/Lexus fits and it's supposedly 27" tall. The L33 is definitely shorter by nearly 3". I'm not unhappy with the L33 choice.

Just for grins I did some math.

In the 2015 Corvette Z06 with stock rear gear (2:41) and stock rear tires (P335/25R/20) and 0.45 7th gear, this 3500 lb car cruises at just over 1000 rpm at 75 MPH. That's about what my little Ranger idles at in neutral at a stop. Incredible !

Considering the higher torque of the V8, I wouldn't hold my breath for this transmission setup to provide the same "miracle" for your Ranger, not to mention the aerodynamics. Well, it would be nice to see what it could do with a Diesel swap due to the low-end torque...

Incredible indeed.

Mine feels dead under 1500 rpm. But in American terms, such an engine is not worthy of the name

Never intended to try it on my Ranger. Barely 110 ft/lb torque. It was just more informational. But still amazing to be going 70+ mph and be turning under 1100 rpm. I'm not unhappy with the 32 mpg highway I'm getting now. I still want to swap the rear end to a 3:55. Should get me another 1-1/2 mpg. 35 mpg/500 mile tank has always been my goal.

I guess it's still not as bad as a 1.0L naturally-aspirated gasser such as the ones I drove

That's a way different perspective.
