Just had one installed on my 66 mustang backed by a 3 speed C4. Nice to have especially cruising at speeds over 50 mph. Best addition on the stang
@squarebodychevyoverhauls69826 жыл бұрын
Totally one of the best bolt ons I have invested in with the truck. Great addition to your Stang man. . It's funny you mentioned your car cause I sold my 65 2+2 in order to pay for some of this build. I bought mine back in 86 for 500.00 and never put it on the road, The only thing I did to it was washed it once then stored it till I could get to it. Well 29 years went by and I figuredII had better start on the tear down or sell it. I guy offered me 10,000 and I let it go. It was then I realized I'm a truck guy to sell a car like that. 289 c4 . One of the best sounding small blocks ever. Great car. Thanks for your comment

If your a real good boy Nate,….maybe Santa,….. who knows who's been naughty and nice,….might get you one and even install it for you ? lol If you love your truck and want to improve it, then you should blow the wad. I hoping to be able to take it for a test run today. I'll let you know if I think it was worth it.
@squarebodychevyoverhauls69827 жыл бұрын
Well I just went for a road test. It drops the rpm 500. That is only going to improve gas mileage, so it's starting to return some of the money you invested in it. What I don't like about it is the shift is kind of on the harsh side. You defiantly feel it when it shifts. Kind of the same feeling of a turbo 400 with a good shift kit. I tried doing 1/2 clutches when shifting and that smoothed it out. I also feel a bit of a torque flex in the drive train now when it shifts into overdrive. It is almost cantilevering 40 inches from the cross member mount now. You probably won't feel this flex the same cause you don't have transfer case on your C10. What can I say. It's great having the extra ratios now, but it's at a price. Depends on how badly you want something ? It also increases your trucks value, and may be a selling feature .

How has your fuel economy improved. I own an 89 Cheyenne C2500 C6P is the package name. Meaning a 350 V8, SM465 heavy duty 4 speed. 3.73 9.5 inch 14 bolt rear end. Gets about 14 mpg. Have been looking at this or the Eaton 2 speed overdrive splitter. Along with eventually giving it a 4X4 tasteful upgrade in the Future once I get a farm rather than buying a second truck. Figured this might be best to adding a 2 speed unit to get better fuel economy overall out in the country and on the highway.

I find I get about 1-3 miles more depending on the grade and load I'm carrying . Its a 307 so its lacking the toque where your 350 would probably benefit more with the GV overdrive . Its also better for climbing hills where you have a gear in-inbetween . Keeps it in the power band longer. I heard a rumour they were going to discontinue the adaptor for the 208 so you might want to check into it before you don't have the option anymore ?

What was your ending driveshaft angle? still 4.5? or higher
@squarebodychevyoverhauls69826 жыл бұрын
I was wrong. It didn't even change the pinion angle. It was so easy to shorten the driveshaft too, and it's as smooth as before.

Why were you concerned about the weights on the drive shaft? You shouldve had it rebalanced before you installed it.
@richaroodledoodle6 жыл бұрын
You don't need to rebalance it if you do it right. It's as smooth running as before and was easy to do

OK. My diveline guy would disagree but looks like you lucked out. I just got one of these units for the RV. I'll be installing this week.
@squarebodychevyoverhauls69826 жыл бұрын
Maybe so, but if you cut the yoke off like I did, cut the driveshaft squarely and mark the placement of the balancing weights with where the yoke was …then there shouldn't be any reason to be vibrating down the road. It should run square and true if you did it right.

How has this worked for you? Any problems?
@squarebodychevyoverhauls69824 жыл бұрын
Like a high performance automatic transmission , the overdrive unit also has a hard shift when the gear vendors is applied.. This is a good thing for strength and reliability , but it can make your dentures fall out . Other than getting use to that ,....its the way to go for a combination like the one I have .The space between 2nd and third was way too steep .Now the GV unit keeps the engine in the power band longer and brings the revs down when crusing on the hwy . Any device that saves you money the more you drive helps to justify the purchase price of the unit.
