    I am looking at buying a 03 cobra and I was wondering, how much the block can handle hp. Because I know they are stock 390hp I was wondering if anyone has there cobra's way above that cause I would like to get to around 500-600hp and I was wondering if thats possible on this block.

    Yeah its possible. Just go look at the SVT forums and see how much people are making in their sigs etc. I believe (i think...) there have been people to make 800~1000hp with twin turbo systems on a stock 03/04 cobra longblock.

    Bottom end is forged from the factory, pretty damn durable.

    Its all in the tune with forced induction.

    HOLY RUN ON SENTENCE BATMAN!!! :rlaugh:

    yes the block itself can handle tons more power, but from what I understand the internals are limited to around 650? not sure though. I am quite sure it would handle what your talking about though

    500-600 hp seems pretty common on those things...the bottom end in those motors is easily built for it. Those cobras are monsters! :nice:

    there are a lot of people that have gotten awesome numbers on the stock blocks, but there are a lot that have had to rebuild as well, I was only at 470 rwhp and 500 rwtq when my 03 cobra engine needed to be rebuilt, tune done by a very reputable tuner. You read about a lot of people running insane numbers on the stock 2v blocks also. The pistons and the hot spot on the driver's side head at the 7 and 8 pistons are the weak areas of the stock cobra blocks.

    a good friend of mine is putting down 740rwhp on his 04 mystichrome and it is a daily driver with no issues on the engine side of things.

    The 03-04 Cobra makes some insane numbers.I have seen KB Cobra's
    making 800-900 rwhp and twin turbo Cobra's making 900-1000 rwhp
    it's absolutely crazy if you ask me!
