What is the stock bottom end in the 99 cobra rated to? Searched and couldn't find an answer, does anyone know?

so are you saying 450 at the wheels or BHP? Because as of right now I have 381rwhp N/A and want to do a couple more mods before before I change the bottom end.

Yes, I already know all that. I just needed to know how much the pistons and rods could handle and i got my answer, I wanted to do a couple more mods before I made the swap. And the block is a Teksid. And when I do buy pistons they will no be 03/04 style. They will be flat top because I am doing an All motor build.

I would agree, I'm not saying it's impossible but that much at the wheels with what you have is pretty hard to get. cuz they dyno about 280rwhp at best stock so your talking about 100whp with just some bolt on's and cams and thats extreme.

I find it so funny that nobody ever believes me, I had 302rwhp untuned without the cams. Then I got the 278's from Comp and installed them and had it tuned. 1st pull it cranked out 368 and ended up with 381 after some changes to the tune. I cannot get you a dyno sheet right now, I am currently in Afghanistan.

just seems a little high to me, have a friend with long-tubes, off road X, cat-back, tune, intake spacer, pullies, JLT CAI, lightning mass air and an accufab twin 65mm TB (basically the exact same set-up I'm shooting for) and right before summer he dynod 349hp and 348tq at the rear wheels. i didn't think cams in these cars was worth what your claiming. perhaps you have a factory freak, i had an old 92 coup with a simple gear swap ran 13.90s all day long.
