Rowdy and Mean 318 build

I haven't read all your previous posts. Why not repair the 360? Did you ruin the block? IMO with the intention of turning 6500 rpm, you should be using forged pistons. Probably a solid cam too. I don't quite understand peoples love for hyper pistons. Sure, you can fit them tighter. Big deal. A forged piston, when abused, will deform before it outright fails. A cast/hyper piston will break into pieces.

"Big deal?" Why yes it is! A tighter fit piston has a chance at less blow by due to less available open area around the circumference of the piston. Which also helps with less piston rock. That helps with piston skirts and cylinder walls suffering less wear and damage.

Normally lighter and still a strong piston, a properly timed & tuned engine will not damage these slugs. Abuse will. Any piston will suffer if abused in that manor.

While the performance ceiling is limited to mostly a NA engine, there are people hitting it with NO2 or a supercharger. I haven't heard of both at the same time though.

I have previously run my hypers to 7K, no problem!

A forged slug is the slug of choice for big power. His build is far far far from that.

Food for thought .... current factory cars are making use of Hyper slugs and making some very good power.
