    Twins with Twins, Anyone?

    Starting mock up process while waiting on that one piece that all this other stuff connect too.. Did receive both Banks intakes last week.

    Twins with Twins, Anyone?

    Mailbu; that's an interesting take on strengthening. I know Mercedes enlarged the mains on their diesels with good success. Owning one I can say, gotta respect the Germans. However I do like those rods he chose. Ford and Dodge use same design. While sizing up oil pans and covers yesterday I...

    Still waiting on cranks... ETA of Friday. Looking for one good set of LBZ/LMM heads, two medium duty oil pans, and one med duty rear cover if anyone has those cluttering up a garage.

    Twins with Twins, Anyone?

    When I was at Callies we talked about the main size, but it's not something anyone has done yet far as I know. If so, all those junk blocks out there with spun mains would be usable again. I'd love see someone do the math and try it. Just not enough time on this build, or would I want to test on...

    Twins with Twins, Anyone?

    Actually yes. I looked at how several big engine builders do it on high HP gas marine engines. Then I measured that first pair of thinned rods on one of the new Callies cranks. Had about 0.021 clearance between them cut to specs from Jeremy's rod guy. That's right at GM's service limits. Once...

    It's beginning to look a lot like Christmas... Boxes arrived today with snow covered piston tops and coned out pins. Also 16 shiny new rods with a freshly narrowed big end. Now if I could just figure out where cylinder #10 is I'd have it made.. :patriotic2:

    Pair of freshly bored and decked LML blocks arrived last Thursday from DHD. :nanawrench:

    Sting, I'm also attempting to make these field trips valid business expenses. I would have bought your lunch, then written off the whole day... You missed out on the Callies freebies. Don't worry, I might run back up and snag them when done.

    SS welds won't rust.. Best guess.

    Twins with Twins, Anyone?

    Grind a small flat on the outside bar edge, then backfill crank with tig and some SS rod. Since ya can't weld to the mallory, just weld a tit to the crank bore that prevents it from walking out. This angle is purely open for discussion at the moment. But since I know of at least two Dmax...

    Twins with Twins, Anyone?

    I never ask about strokers. After walking around the place, not much they couldn't build if the demand warranted it. They also make rods, just not for Dmax yet... However they did say if anyone needs new OEM crank gears, have plenty in stock.

    Twins with Twins, Anyone?

    We talked a good bit about the wicked Dmax harmonic yesterday. They believe, as has been mentioned on here several times, that the lack of main bearing to rod bearing overlap is likely the weakest link. Not a problem to oversize the mains if the block will allow it. Wish I had time to test that...

    Twins with Twins, Anyone?

    Needed to cut the chamfer side of each rod about 0.045 - 0.050. They narrowed the rod journal 0.090 from stock. Actually they are only around $3,500 stock balance, and $4500 for internally. I ordered 2 from Jeremy, since majority of that rack is bound for him anyways... Was really cool to see...

    Twins with Twins, Anyone?

    Needed to check our rod clearance and chamfer adjustments to fit the new Callies cranks. Since we don't have the cranks yet because they're waiting on bob weight figures to balance them, found myself in a catch 22 situation. Luckily Callies facility is only a few hours away. So I grabbed two...

    Twins with Twins, Anyone?

    He called me soon as I posted that.. Has a zero flywheel with TC bolt pattern setup we can just swap into. Plus has an adapter that weighs more than my flywheels, so problems solved.. :thumb:

    Twins with Twins, Anyone?

    Hey MarkBroviak, what are the popular bolt pattern options for an engine dyno coupler? I'm finishing up the zeroed flywheel details and just realized I won't have a standard TC pattern. Bolt pattern I'm drilling will be for a 26 spline marine damper, 8 bolts on 9" dia below. If you have a...

    Twins with Twins, Anyone?

    Figure if can make that fast, than everything after should be easy. LOL It did run 100ish with 950 gassers. Transmission plans got changed due to missing out on the only pair available in the version I wanted. They were custom built 1.5:1 first and 1:1 second. Next choice is the COAN Marine...

    Lml dsp5?????

    I'm not going to divulge any secrets about Ben's work, but we've both spent a bunch of time over the past year hacking the canbus ArbID sets and reverse engineering GMLAN language. Completely legal, and no different than what the EFIlive team does every day for a living. While Ben's focused on...

    Received more pictures today.. Thanks Fingers :hug: We also have the custom billet zero balance marine flywheels mocked up in Solidworks. Still reviewing some spring damper bolt pattern options. Estimated to weigh in around 65lbs as designed. Was planning to go a bit heavier, but realized the...
