I keep debating on how HP I should do with my stock 5.0 block, since I will be going back to the dyno real soon, how much HP would you guys push it, its a track only and has a 70mm turbo?

....AND the balance job. I've seen stock blocks live at 550-575 levels for a long time if the balance job is spot on.

If it was ready I would be there for sure. I'm missing all this cold weather ![[Mad]](mad.gif) ..I'm still assembling it after tearing it down for paint. I'm finishing up on my black interior conversion and rear seat delete. I want to make it to the Fabulous Fords show at Knotts....I want to see what yours can really do with that YSI.

You can have a kazillion hp on the stock block, but if your not taking it out of the garage it will definitely last a very long time
I've seen stock blocks with 550rwhp last in the 100+ K mile range, but they were spot on with the tune, well maintained, good balancer (harmonics are bad for motors) and were not abused on a constant basis.

'95 Cobra/TFS TW heads, tfs1 cam, MM suspension, vortech S-trim, and a zillion other miscellaneous stuff that is costing me too much

Ford Rates them at 450FWHP.
Depends on the setup. Pump-gas motors won't last as long. Any sort of detonation will bounce the caps on the block.
My original Byron tuned TT 331 twisted the block with 430/507RW. Of course, this was with 7psi on the dyno & she made 11psi at the strip with the same tune.... Inertia Drum's FTL (with a turbo car). I'm sure if I'd have run straight 100 she'd be running still.
RPM has a LOT to do with it as well.
The wife's all-motor setup is pushing the limits of the stock block. Upon freshen up I noticed material transfer from the caps to the block. (walking the caps at high RPM) Hers is making 442RWHP at 6400RPM & she shifts it at 6800.
Dart is in the process of releasing an SHP SBF block in the $1500 range with 4-bolt mains. It'll handle well over 1000hp.
