306 or 347?

[~The Jester~]

NEITHER! Build a 331! Best of both worlds. 347's have a horrible rod ratio, and supposedly won't last long. A 331 has a great rod ratio, and is obviously more cubes than a stock crank. We have an N/A 333 (A 331 that's 4.040" bore instead of 4.030") that runs 11.70's all day long. Good set of Canfield's, victor Jr, Cam Motion custom cam, and an old school toploader 4 speed. Can't beat it for the price man! Build your "recipe", then call Cam Motion. They'll build you a custom cam that'll light you up! Think about it, a 333 cid motor making over 500 ponies? Waaaay cool, man. Way cool!
