How much can a stock block handle

[lycan284]

How much horsepower can the stock 98 gt block handle, before things start to break and melt. I am putting in forged internals, and I am looking at running around 600hp eventually. I just need to know if I can do it with the stock block.

600hp, supposedly

Me, I would go with something else if I were starting from the bottom up anyway.

? is there another shortblock to start with? Just wondering cause it seems all the ones I see are stock blocks that have built bottom ends?
But to original poster it appears they will support 600rwhp the real ? is how long will they support it.

The block itself (not the internals) are good for over 1000hp. The internals depend on what you get. There are no aftermarket 4.6L blocks only built short blocks from places like DSS, CHP, MMR, and SHM.

Something else, as in a completely different engine (like the 5.4 swap, the 5.0 cammer, or a 32v setup from a Mach for $5k).

Pushing a stock block, in my opinion, does not do much for my goal of streetability with high mileage.

the internals 600, and ive also *heard 1000 for the block
the thing is the tranny gets suspect at 350hp

Yup, go for the knockout punch, the TKO 600!!

If an aluminum explorer block can handle 1500hp, I'd think the iron block could handle more.

no way would I trust a 00+ Aluminum Modular block to handle that much hp.. it's just not strong enough.. now the 93-99 aluminum Teksid block yep...

no problem using your block, if you put good internals like you describe , everything will be fine. stock internals, crank, rods in particular wil start having problems around 500 hp. the blocks are not the problem at all.That is a 5.0 thing, where you get around 500 hp and the internals are good but you make two 4 cyl out of it.
