    8.25 Differential Question

    You do not need to change the housing. Just buy that carrier and install any gear larger then 2.71:1 you want, if your 8.25 is the older produced between 72-96 with 27 spline axles :)

    Shims Under Main and Rod bearings

    Think the compression will be somewhere 8.8 depending on final measurement. Here are pictures of the bearing. When I measured the journals I did check them 90 degrees apart. I did not find any R on the crank and the block got no maltese cross. Below are some pictures on what markings and...

    Shims Under Main and Rod bearings

    Thank you nm9stheham for taking your time to answer and explaining. Also appreciate all you others for taking the time. My guess is that the bearing fitted from factory is a .002" bearings and that's why the factory bearings are marked "AT-20". When I measured the rod journal again today it...

    Shims Under Main and Rod bearings

    The OEM bearing are marked AT-20 so that's why I thought something was 20 something of. I made a mistake when measuring my rod at first so that's why I assumed it was the rods because the mistake measurments was 20 thou off on the rods. I'm not sure any more what to think but I will measure...

    Shims Under Main and Rod bearings

    nm9stheham I will measure the rods tommorow at the break. But I think I may found the problem now when I was calculating the measurements taken on the rod big end from mm to inch. The measurement at the rod is actually 2.250" so a STD size bearing should fit then. The old bearing fit tight when...

    Shims Under Main and Rod bearings

    I also think that having the correct bearings would be the best RAMM, but since I live in Sweden and parts are non existent and I have to order them overseas and that cost a lot. I now already have STD size bearings that fit like they should against the journals. But I have a small gap between...

    Shims Under Main and Rod bearings

    I cant see why the rod would be out of round if you fit thin brass shims between the rod and bearing half Halifax? Toolmanmike if the engine left the factory with oversize rods with bearings that fit, why would I need new then? Doesn't machine shop sometims oversize crank bore and rods? The...

    Shims Under Main and Rod bearings

    Hey guys and girls I just bought a 75000 mileage 318. After doing a compression test the cyl 2 failed because a cracked valve seat and cylinder 2 have bad pitting. So I sent the block to machine shop for sleeving cyl 2 because the other cylinders was in really good condition with minimal wear. I...

    BBP to SBP 8 1/4

    Thanks bluNblu this is why I asked for guidance, would never think of the hub centering the drum. Just need to leave the thickness of the drum on the hub when turning down the other part of the hub. The task getting clearer and clearer. When I measured my 7 1/4 I had about 2" between the wheel...

    BBP to SBP 8 1/4

    Thanks for the comments on the subject. Will check Dr Diff but I guess that option is to expensive. I took the drum of today and it is alot of material between the studs. To me it looks like a done deal to drill new holes between the old holes. Just need to find a machinist to do this since my...

    BBP to SBP 8 1/4

    In a package deal I got a Volare 8 1/4 rear with a cone diff and 3.21 ratio that I want to put on my Valiant. I know the the Volare rear end is wider and that the spring perch location is different. But the problem I have is that I want to run my 5.5" SBP steel rims. So I want to redrill the...

    Band adjustment methods?

    What I did was jacking the rear up and put transmission in neutral. This procedure is for only adjusting the front band. First loosen the lock nut, then you just turn the adjuster screw in and at the same time turn the driveshaft at both direction with the other hand. You need to turn the...

    7 1/4 Rebuild on the cheap

    Thanks for the compliments and comments :D I like to try to make my own tools before I buy them. I have a bucket full of scrap metal that are often perfect for this kind of tool making. I drive very carefully so I think this axle will hold up fine :) After I testet out which spacer and shim I...

    7 1/4 Rebuild on the cheap

    When I bought my Valiant about 2 years ago it had a rear end bearing noise. Since it's my daily driver and I didn't know which bearing it was or how to fix it then I just drove it instead. But recently the sound got louder and shifted in tone and I could hear that it was from the left outer...

    Need help, advice with my 318 build

    I have looked at the Lunati 10200702 cam as a possible cam to change to if I'm not satisfied with my current cam. Have looked at the XE 262 and also the 265 DEH as RRR suggested. But think the Lunati seems the most appealing for they are designed to work together with the .904" lifter diameter...

    Need help, advice with my 318 build

    Sorry for a very slow reply. But I have been busy lately. I'm done with the grinding the ports. I have left some polishing of the exhaust ports and maybe the chambers. Have cc one chamber at 61cc. But I'm little worried that I removed little to much at the "short turn radius" at my exhaust...

    Need help, advice with my 318 build

    Thanks for all response in the subject. I feel fine not going crazy at port matching as my starting idea was just to make the ports more even and a little better flowing. As I understand that smaller intake ports helps keep the port velocity up which in that case helps the lower rpm torque? Also...

    Need help, advice with my 318 build

    Thanks for all the opinions and guidance it really helps. I want to make the engine, trans, gearing and suspension work together well. My goal isn't really to make that 275 - 300 hp my goal is more to make we say that I'm going to have 250 hp at the crank. That those 250 hp is utilized and...
