    Twins with Twins, Anyone?

    My only question from day one has really been using C gaskets. My Dmax tech buddy has always preferred C, and that' what we went with. However, with the extra .005 on the deck, or extra .005 off the pistons, they will clear A's without issue.. Doesn't explain why one engine is fine and other is...

    Well..... I purchased these LML blocks from DHD and Tony's guy did the bore and deck. I requested they be decked .010 and they arrived stamped .005. When I called to ask, was told they didn't need 10. To which I replied, I'll tell Fingers to add 5 back to the piston tops then..

    Well that's where things get really strange, and this block question comes in to play.. Ya have 2 identical engines, both running same RPM and HP most of the time. Both tuned identically. With boost in the 30-40 range, no issues on either Above 40psi, one engine starts leaking into cooling...

    Nice catch. See the matching marks in the head pic? Those nuts on that bottom row seemed to come loose easier than all others. Made me watna grab a toque wrench, but I didn't.. However ones on the others head, felt exactly the same when breaking those loose with a bar. And no leak over there...

    Best I can say, the issue lies under that bottle above somewhere.. lol She was leaking between 4&6 for certain this time. Got a nice soot line on head and block. Cyl 4 has a line that looks kinda like a crack. Upon further inspection, it's actually block sealer that seeped in when I shut her...

    That's what boat had to begin with. Where's the fun in that? Na these bitches be nasty.. Anyone whose rode in it will attest, way cooler than any 9L gassers. And when I cranked em up at LOTO and she smacked 91mph without even trying, even I felt they were nasty again... Think we've covered...

    LoL. Think I'm gonna make a roaming gnome style / 101 good uses, splif off those two pieces... On a lighter note, the built in drink holder works very well, and injector coating trial says BIG [emoji106] [emoji106] [emoji106] Sent from my SM-S901U using Tapatalk

    Problem Child got a bath today. Believe it's about time to turn on some jams, break out the party flavors, and finally get to the bottom of this nagging freaking head or block issue.. Sent from my SM-S901U using Tapatalk

    What did you do at work today?

    Hotwired an old oil burning furnance with recycled C15 engine parts. It's a work in progress, but improvements are visible already. Run #2 gonna remove the piston rings.. Sent from my SM-S901U using Tapatalk

    Chevelle upgrades.

    Hope ya don't experience what I did with race cast pistons. Took a used set that had about 20hrs at 800hp in a boat when one cracked. Put that set, along with one new in a 500hp boat engine, only made it about 10hrs, she cracked another.. Scrapped the whole set and went ovals since it was my...

    Those were some healthy looking pistons and rods. Which made me ask a stupid question, "why so big if only 500hp??" Duh... Factory torque spec is 1550-2050 lb-ft @ 1200 rpm. And they put a marine cam in it, that raises the curve and R's a couple 100. Now it makes 600hp. Ok impressive. But still...

    I can read and calculate exactly perfect engine load values off the ecm directly from canbus, then that gets translated to a PWM voltage to supply fuel pump without need of a return or external regulation. Sent from my SM-S901U using Tapatalk

    Now you guys can help convince Fingers to build us some of these 2 piece steel / aluminum pistons. Helped out by only watching, a Cat C15 rebuild last week. Can't believe the simplicity of this piston and skirt design. Why hasn't anyone tried this yet?? And love these one wasnt big enough, so...
