Im looking to make a 306 NA car and i was woundering what u guys think about Keith black pistons. I know they are not forged but a motor with stock rods and crank I figured it would be good for 300 rwhp with the right combo. let me know what u guys think thanks greg
if you read some of their tech articles, I think you'll find they make-probably-the best hyper piston you can get. they've even used them continously in sprayed engines without incident. you just have to install parts (rings) within the specified tolerance, and keep it in good tune, and they'll provide you a lifetime of good service...hyper pistons are usually a little bit lighter too
My brother and I use them in our N/A 306's with the stock crank and stock rods (all reconditioned of course.) We spin 'em to 6,800 rpms without incident and have had zero problems. See my other post in your other thread.
