To stroke or not to stroke......

70Barracuda,
I agree with the 378 CI 's, as piston speeds get higher the more cylinder head that you need, look at a big block chevy, 4.0 stroke and 260 round port, and 290 cc square port heads. There rod ratio work's out close to the same as the stroker small block mopar. You would have to run W-8 or W-9 heads and this just is feasiable for daily use. For what the heads and valvetrain would cost you can build a complete engine that will fly.
