    Mystery rear main seal size

    Its got a 84 DA seal in it but needs a 86DA unit. Same size as a EF seal.

    You need r's on a EFI engine so you don't cause signal interference

    clocking rings 250 crossflow

    Sooooooo...tighter you set em longer they last usually but there is a limit to both sides of that comment. Some work on x.007 of bore. I actually set my Wiseco's at 15th top and 2nd 17th 8 years ago. After much of that time NA and 8200rpm and later a P1SC Procharger I pulled the bottom end down to ready for a freshen up and found there at 26 and 28th respectively. My turbo combo will be set up the same with 26th top 28th 2nd. So I never go crazy on ring gap and TBH 20-22th and 22-24th on a stockish engine set with 3or 4th piston bore clearance is heaps IMO.

    Pushrods and lifters (if flat tappet) do too. Along with valve springs if you watch a spintron in action.

    clocking rings 250 crossflow

    So first thing to know is the rings rotate in the bores as they go up and and down so don't stress too much. But for the argument I set the oil rings 180 apart from each other and find a spot on the piston im happy with. Then the 2nd ring goe's as far away as you can get it from the "top oil ring" gap. Then the top ring is 180 opposite the 2nd ring gap. But the rings still rotate in the bores at there own rate anyway so don't be too concerned.

    They spin in the bores. If they do not spin you wipe cam lobes. 8mm 1/4 drive on a battery drill fits in there with manifold on.Done it heaps.

    Interchangable Balancers

    Crank snout stuff is the same. Offset belt size is the issue later engines use serpentine belts. FYI I use a SBC ATI damper on my xflow.

    Air filter size Aussie speed

    A traditional filter is to tall but a flow thru filter top is the go.
