I'm thinking about purchasing a new mustang. What is the most HP that you can reliably push through the stock block on boost?

400 RWHP to 450 RWHP seems to be safe.. from what I have read and seen .. some may give you higher numbers.. but I wouldn't go over that on MY car.. unless I had a different block.. ( which a lot of people are doing .. and getting very high numbers )

JMO and only that..

400 or so max. Donot get fooled by some of these numbers of 480 etc. Most of these guys with high dyno numbers are from a dyno jets which will give you a much higher number. Stick to 400-420 area and you will be ok.

Stock Block or Stock Internals? Because there is a big difference.

Isn't the Shelby 500 w/500HPa blown 4.6? What mods does it have? Probably a lot of internal upgrades I would think.

The GT500 has an 5.4 L 4 valve engine with an Eaton Blower. The engine makes pretty good numbers, but its heavy as all hell. Iron Block < Aluminum Block

Our GT's engine block can hold 800 RWHP, but our internals are only good till 400-425 RWHP.

So that's almost 900 HP at the crank right? Around 880 HP?
Not bad except nothing inside will stay glued together from what you're saying.
That sucks but all too common I guess.

I know, that 5.4 liter isone heavy monster!
I'm thinking, well dreaming of when I can afford a BOSS 302 crate engine and swap my 4.0 out for it.
Now that's what I call excellent HP to weight ratio all around!

Stock block and stock internals.
Also, the Shelby will be able to withstand more than a standard GT. It was built for FI.
