    So I got my NV4500 installed last week, just intime to go up to Pincrest to go camping. It shifts so easy, the hydraulic clutch is really nice, and the best part is that I went from 7.5 mpg to 12 mpg!!!! And that was uphill. I know a little bit of the mpg increase is from putting on the 38's rather the 42's, but still. I am so happy!! What a difference OD makes!!

    i take it you swapped that for your 465...how straightforward was the swap? are you lost without the low gear?

    How about more info??? I have a 88 crew cab with a 454 and 465 and would love 12 mpg. /forums/images/graemlins/eek.gif I've even considered the overdrive units.

    Just make sure if you plan on pushing some power thru 5th to get the upgraded 5th gear. That seems to be the only weak link of the NV4500.

    The swap was easy I got everything from a 93 chevy bellhousing, hydraulic setup, starter, tranny. Everything went good, I got the adapters from AA bolted the t case up tp he tranny. The chev nv4500 has a harmonic balancer on the back of the tranny and you have to take that off and cut the mainshaft down. Then theres a coupler that mates the tranny to the 205. I bolted it all up in the truck. AA had an adapter to bolt the tranny to the crossmember, which didnt line up, youd have to drill holes and move the crossmember back but instead we made a mounting plate, which worked perfect. I think the whole setup is about 1" longer, i have plenty of slip, and no vibrations or bind at full droop. 1 thing i fergot to even think of was the flywheel, It rubbed on the bellhousing but it has worn, so now its not noisy anymore. My tranny was a '93 so it still has a 6.34:1 1st!

    how did you mount the clutch pedal? i got one out of a '94 with all the hydraulic stuff and am working on putting it into a 77, the thing is the brake booster is invading the space that the master? cylinder supposed to sit.

    if you use the pedals/master from the 85+ versions it puts the master lower and to the ds of the booster

    I took the whole pedal assembly, which was at an angle, cut off the neutral saftey switch, and cut the corners out then made it square, so it would fit under the dash, and welded it back up. Then since the angle was taken out and not inline with the master, I made a different pushrod, one that was stronger, that went up into the master cylinder. The pedals not in line with the otheres anymore, so thats one thing im going to have to fix.. All you who are intrested, Ill tell you what. Im starting school tomorrow but give me a few days or so and Ill try and get pics of it all so you have a better idea.
