400ex are RELIABLE as all he!!. i love mine, and am planning on doing a sparks National 440 kit. ported, 11:1 they are FAST then. pushing upper 40's to 50hp. i wouldnt doubt a stroked 465 has 58hp.
i would take a 400, over a rappy on the track anyday.
"this pro racer" has a big lip, but cant backup what he writes.... lets see some pics pro racer....
