    Default 10,000+ rpm high compression build what are good mods and what block is good for it?

    Hello based on my title I was wondering if you guys knew of a good build for a high revving Mustang engine for a 93 Mustang other than putting a coyote in what block is good and what mods are good to get a high-revving V8? Is a 302 Fox block good for a High Rev engine or would a 351 or 331 be good for High Rev engine build?

    Get ready to open your wallet and spend a lot of money. A reliable 10,000 RPM small block Ford is easily going to be a $20,000 build.

    You will need an aftermarket 4 bolt block to spin 10k RPM. A stock 302 block will have issues with cap walk, and harmonics. It just isn't rigid enough and the main bearings aren't supported well enough for that kind of speed.

    Along with an aftermarket block, you will need lightweight rotating assembly parts, low friction coatings on the piston pins and skirts, solid roller lifters, shaft rockers, lightweight valves, etc.

    Not if you want a 10,000 RPM pushrod V8.

    You can easily build a 7k RPM SBF that will live for a long time. Beyond 7,000 RPM, harmonics and valvetrain control become challenges.

    You can always build a 93-2004 DOHC 4v 4.6 motor, Simple spring and cam swap, and all day

    Something else to consider... When it comes to push rod engines spinning to 7000+ rpm the camshaft in most cases is not very street frendly. Thats why you will see most guys go with 6000 rpm stock block combo and a blower or turbo setup. Its cheaper in the long run, makes more over all power and it reliable when done right.

    Why do you want to spin to 10k rpm?

    In addition to what has been mentioned, I'll add this: any engine that spins up to the 5 digit range is going to require constant maintenance, to the point it's going to require a schedule. Especially a heavy bobweight V8.

    Now a rotary swap into a notch back would have my attention
