LMS says 450/450 to be safe...
Other tuners suggest 500/500 but that is more of a drive train limitation on the transverse setup...
This is assuming it’s a SHO or MKS or other transverse setup..
F150’s someone else would need to answer...LMS suggests 450/450 on these too iirc...
Just the block alone? Not sure if anyone has tested that...

Well, if you want to max out the stock short block, is a bet you could get one good 1000 H.P go from her. Maybe a little less.

Thank you. You understood what I was talking about and I truly appreciate it. Even attempting 1000 hp on a stock Shortblock(when I say stock shortblock I mean stock internals with a stock block) is idiotic. I didn't know what the stock drivetrain and shortblock limitations were. Now I do. Thanks again.

The horsepower mark provided to me by one of the engineers who worked on the GEN4 platform when the SHO was reintroduced was relative to the transmission failures.
I was told in order to not experience drivetrain failures, I need(ed) to stay away from 720.
That # being crank horsepower.
I can't recall if a test, company wise, or individually, was ever performed to test the stock engines utmost limits.
Suffice to say, there have been plenty of failures documented all over the net (of stock engines) so I wouldn't imagine it's a high value number.
That's for sure.

Thanks again for the info. I want to break into the 11's on stock internals with the billet wheels. After that, I would like to take her to the drivetrain limitations. I have some goals. First things first though!

Not sure what the point of trying to get more out of the engine than you can safely push through the craptastic JTEKT AWD setup we have. Just asking for trouble..

@SBS......
I wouldn't sneeze at a benchmark of 720 (chp) out of the Jtekt setup.
That's actually fairly stout IMHO for a bone stock drivetrain.
It may not arise to the levels you, I, and others want to see out of it, post modification(s) that is.
But for what it is, it's a really good product right out of the gate.

Yea.. thats about 554awhp with 23% drivetrain loss... maybe I am being a bit harsh... as thats double the factory output..
