Gear Vendors OD

Gear splitting with the GV was mentioned and I do think that’s a significant advantage. It turns your 727 into a six speed.

Please note that almost all of the increased MPG will be on the highway, IE extended periods of travel in OD.

That's just the way it is, even with new cars and today's technology.

Stop and start city driving is an MPG killer in any car.

My commute has a few stretches of "get to 60 as quick as you can and then stop" that also sucks MPG.

If you won't be doing a lot of extended (no stop signs or traffic lights) driving, that OD might be a waste.

OTOH, if 50% of your normal driving pattern is non-stop, you'll at least be getting improved mileage 50% of the time.

Where in MN are you? Tranztech in Dubuque Iowa does OD conversions.
To me, if you want od you really need more tq either with stronger engine or more rear gear. 318 with 2.50 gear probably has poor vacuum readings lugging along as someone else mentioned. 80's 318s did it but with 302 casting fast swirl heads.

I will be running 75-80 mph for extended
periods. The vacuum in my car is fantastic
at cruising speeds (18-20). At 75 mph should be around 2300 rpm. Plus the ease of installation
makes it very enticing.

I would guess the gear vendor unit weighs about 70lbs. Not to include the housing extension.

Is the 70 a typo? I haven't separated the components on the used setup I bought, but I can't see anything that looks that heavy.

I'd be amazed to learn that the GV unit weighs more than 35 lbs.
Maybe I'm just an unusually strong man but it didn't seem that heavy to me.
