    Spray bomb rebuild is almost done just need to put the pan gasket on it. I used a freeze plug to 86 the low oil sensor. 3/8" weld bung for the oil return. It's the special YYY block lol .. the Y's were pulled off the production line and spec's checked that's it.
    I did arp head studs and a fresh set of gt40p's my good friend Eric rebuilt. I replaced the timing chain .. it was really sloppy. 9333 pt1's for head gaskets.

    I had to cut the rear ports on both log manifolds and reweld them. Both of them moved quite a bit when I separated the header flange. I can't get a .005" feeler gauge in any of them now. Waiting on header gaskets and then I'll pressure check it to be sure no leaks.

    I could not get the vband clamps to seal. Two of them have the male/female ends. I added a bellows on the crossover thinking it was binding but no change. I ended up making copper fire rings out of 12ga Romex.
    I started on the suspension del alum control arm bushings and Howe custom ball joints 1/2" extension.

    Do you have a picture of the fire rings?

    Here you go. I soldered the ends together. I started with 18 gauge but ended up with 12 that gave a slight crush and no leaks at 30 lbs.

    Did you do anything to index them in the v-band? Are the V-bands flat on each side or have a step on them?

    These have a step in them and the ring sits in the recess I'll get a pic next time I get a chance.
    The vband on the driver side is the flat style I used the 18ga ring on that one just glued to the face. Not sure how that one's going to work out

    Fire rings. Reamed the spindles .. I matched the depth of engagement to the stock sn95 pin which seated had .850" the entire taper is 1.1". I used Brutus to do the reaming.
    Don't waste your time with the junk $40 reamer on Amazon it refused to cut. The $130 reverse flute reamer from Howe did the job NP. PXL_20240713_144037365.jpg #ad
