As far as I know, the mains are still the same size. I don't recall reading anything about that dimension changing.

Argh! My fault. It's the LFX that uses a 3.37" (85.6mm) stroke...to help it achieve 3.6ish liters... I have one in my truck (Colorado) but engine covers prevent me from getting a good look at the block.

The blocks don't look that different at all.



I guess you don't want a 3" stroke crank, then...

The 2.8 crank? Uh no.

Though I am picking up a Saab F40 6-speed from a 2.8 turbo... It's just a mini-LFX right? LOL

That would be me 😁

Well... it's a billet crank from the big time V6/60 racing days

Yep you are right Will but that test was Dynojet sponsored. But to get that out of the way I took my 2.8 to both dynos and look what happened.

Dynojet dyno

Mustang dyno

Exactly the same!

But like you said, I use dynos as a tool to measure my improvements not to brag.



I can tell you guys, at Superflow, our chassis dyno has a DynoJet correction factor, because of how their software creates power numbers, its there to help the shop owners create consistency for their customers.
Dyno's are a just a measurement tool, and it is up to the user to apply them correctly to gain the results they're after. No manufacturer that I am aware locks the calibrations up so they are set to some permanent standard, all of them can be manipulated by someone who knows enough, or is ignorant enough to just go after numbers.
