    Twins with Twins, Anyone?

    The shaft slides into the damper, and bolts thread into the rear cover, so it must be close.. Assembly takes a 1/4 turn of the engine to line up the access holes, but chit fits. Now I just need to find a dyno with that matching 8 bolt drive shaft flange pattern and we're set... :D

    Dyno adapter assembly done !! Tempered the spline shaft at 800F, then let it cool overnight. Which changed it from the nice pretty black to dull brown. Then we had to heat the end plate to press fit onto the shaft with only one key. Then drove second key into the slot to lock it in place...

    LMM: Ever Seen a New Engine Do This?

    I once fed a fresh 351 Cleveland a Big Mac and half order of fries on a bet. Snapped that 750 Holley wide open and tossed in four chunks. It never even burped.. Spared the coke chaser however since sugar crystallizes. Couple weeks later it broke the cam and grenaded, but the cylinder walls look...

    BTW anyone remember what the 2 different threads sizes are used in oil LML oil galley plugs are? The LML oil pressure sensor is conflicting with my coolant hose routing in pic above. So gotta plug that hole, and go back to LMM/LBZ sensors. Also need to stick a temp sensor in another.

    Ya every so often brilliance gets in the way of progress... But usually time constraints limits such issues. However my brilliant idea to block the original cross over passage in rear cover happened in the early stages of the engine build. Sounded good at the time. Now I have to deal with that...

    My machinist buddy and I tried our hand at heat treating the adapter shaft tonight. Wrapped shaft in stainless foil, heated to 1600 for an hour, and then quenched in water. All machined surfaces look to have maintained fit dimensions. So tomorrow we'll move to the tempering process. Then press...

    LMM: Ever Seen a New Engine Do This?

    If pistons are too tight, your typically gonna see some aluminum streaks stuck to the walls. Not as "clean" as this one. Recently saw pic of some big HP Cummins pistons and block where clearance was an issue and, it gaulded streaks into the block. This one looks more like a fine abrasive issue...

    LMM: Ever Seen a New Engine Do This?

    Are all those piston tops the same color? Doesn't look so in the pics. My first though is something mildly abrasive has eaten up those cylinder walls. And for certain your reason it was burning oil. If piston to wall clearance is correct, then I'm leaning towards coating adhesion issues.. There...

    I have a friend that does laser engraving. Maybe I'll send em out to him update specification.. For a few weeks I've been trying to figure out a thermostat housing design that will allow clean mounting of a reservoir tank on front of the Banks intakes. I had some base plates cut out a while...

    I'll just hit it with die grinder and buff that right off.. Think I'll leave the "See Owner Manual" >> :roflmao:

    Oil level indicators also came in this week. Was able to tweak the factory medium duty dipstick tube to fit nicely inside the header. But level indicator was way off for these modified deep sump pans and baffle plate setup. Little searching led us to use 2.0L cavalier sticks, which are...

    Sat around for couple hours looking through a Gates catalog for specific molded hoses to help finish up these cooling system. Then drive to the local parts store"s" to find they have zero of those part numbers in stock.. So that's when you ask to just pick some off the rack. With some light...

    Yeah it's gett'n tight back there now. Still have to fit a pr of turbos, catch can, and related hoses. On the front end, a coolant reservoir of unknown capacity for starters.

    Wrapping up the charge cooler tubing. Things are getting pretty tight on the back side of engines. A couple tubes need some tweaking, but ya can still get a lifting strap through the eyelet on rear cover without obstruction.

    In a 3/4 mile run, I'd generously spot him a few boats... :spit: While on the big end, that Skater hull should be substantially faster. But gearing has him limited at about where I plan to top out. He needs my drives. My problem is, Tyson has the only decent set of un-cut 17.25" x 40 pitch...

    Picked up remaining pieces of the dyno driveshaft adapter tonight. Gotta balance the hub, harden that shaft, then press everything together tomorrow. This piece would make a nice generator adapter when we're are done. Or maybe the first Duramax sprint car. LOL :woott:

    Unless there's something recent, the big black and silver cat you thinking of has a pair of Industrial Injection Cummins in there now. Same one I mentioned above, that shold be there for the shootout. That Wagler Dmax with lexan valve covers, most of it is setting under a tarp in a boat shop in...

    That's the spot.. Actually best place to watch from is up on the cliff where they hang the radar gun off a 40' pole. Now imagine flying by that point at 200+ mph trying to center up on the gun for best reading. Below is Top Gun last 3 yrs. LOTO recently cut that course back to 3/4 mile...
