OK guys I'm back with my 727 endplay problem thread and although you all had good suggestions, the problem was not any of them. It was the all new rings and bushings. I sat down and thought about this long and hard. I pulled all the thrust washers out, no difference, then I stumbled upon[...
no , none of these are lock up units, I made sure of that. Not all later trans were lockups and from what I understand BB Lock up trannies were kind of rare.
Yes I had to swap in a couple worn items, but I cant figure how this would do this to my endplay. I took a rear drum from a 74 because the 78 rear drum was seriously used up. I replaced the rear sprag with an A and A ultimate sprag. I also removed the belleville spring from a 76 unit. I...
This is sure to try some patience. Ok I have been rebuilding a 1978 BB 727. Came from a truck or van I believe cause it had the 4 gear planetaries. Also has the metal cloverleaf style thrust washer.
I did not check original endplay, I know, my bad.
I have been working from the Munroe book...
Yeah they are 292 Chevy rods. I figured it out. I loaded it all up and took it to the machine shop. they told me those pistons would never last on the street. The rods are way long at 6.76 inches . and yes some BB Chevy rods might work . That's what I need is lightweight BB Chevy rods ( like...
I cleaned up the crank today. Journals all look great. The seal surface where the front seal rides is not so hot. Don't they have a repair sleeve for this?
can you guys tell if this is a forged or cast crank from pictures. I would imagine its forged,
OK, at long last I have determined the connecting rods are 292 Chevy straight six rods. All three dimensions match, and they look the same in the details. Length of the 292 rod is 6.76. So if I did want to replace them with new remanufactured or NOS rods it would be fairly cheap. And they are a...
Yeah I haven't found a small block Chevy connecting rod anywhere near 6.75. Pontiac 400/455 rods come close at 6.67 or something like that. When I find one rod close in length, then the two ends don't match up
I got rid of the heads, as I could tell they were not street friendly, and the intake had been seriously cut down to match.
The pin diameter is 29/32.
As to my measurements, remember I don't have mics , so this is just ball park, probably off by a bit
piston diameter is 4.25, crank journal diameter is unknown because I don't have a mic big enough, but I did put down the big end rod size as 2 &3/16, so add bearing thicknesses and it should be around2.25, maybe slightly smaller. The rods are clearly factory as they are marked GM and some other...
