I have a 1000se 4.75 MMR Stroker, stage 3 heads,cams, and iron block. I’m pushing 638whp, 590lb torque on 12lbs and E85.
With some upgrades over winter I’ll probably see close to 700whp. This is at 4200’alt. I’m changing out valve seals and that’s all I’ve had to do this internally. Fwiw I purchased this engine out of a wrecked car, so I’m not the original purchaser of this engine, and I really don’t know for sure the mileage on it but I have the build sheet from 2013. I guess if I had to do it again I would, but only at the price point I paid. I wouldn’t consider buying new from them, based on my limited interaction with MMR, they don’t really interact very well, return emails, give information, on past builds, specs on cams, even with offering to pay. Just my 2cents.

Guys you need to look at itsjusta6 latest video tearing down a blown engine (1) Tearing Down Satan’s Blown Motor! | 1,500hp Coyote Engine Teardown - YouTube . Maybe he will finally stop using fucking MMR.
I've used MMR parts in my coyote motor and they have held up beautifully. I think we all need to realize, Itsjusta6 is an asshole and doesn't know much. He breaks shit all the time. I think is mostly intentional so they can make more videos and keep the subscriber and view counts up. I will continue to use MMR and not worry about what YouTube clowns do or say

Or just build your own engine. Its literally just knowing how to use a torque wrench and measuring tools....and common sense.
