I was thinking of the same thing, I was going to port it, and get a tuned exhaust. With a 50 tooth sprocket, should be able to throw a little mud with that.
I agree Steve. The 460 motor is decent but I know when they first came out, the chrome plating on the cylinder walls would peel off and the pull starters would last about a week of you were lucky. The pull starter is really recommended. Being stranded because you can't start your motor really sucks. Chris (Chevys) he knows 460 very well and he builds and ports some of the fastest 460s around.
i'm a participant over on gopednation.com where these engines are very common. you can find many posts in the archieves about the poor quality of the cylinder plating from the very start.
over the years, the incidence of failures due to the plating has slowed to a near standstill, though there's no guarantee it couldn't happen.
following a conservative premix ratio with very high quality synth oil seems to be the best insurance. i'm using amsoil saber mixed 65:1, 1.25 turns on both needles.
i changed my base gasket from the stock .020" paper to a .005" copper gasket and picked up noticable midrange torque.
to the point, i'm not aware of anything else this engine needs other than a drive system that can handle it. this engine also prefers atleast 21-22:1 overall gearing on 26" tires.
Detonator:
I won't be ordering the engine immediately cos i'de like to see how 5-7's friction drive turns-out(particularly with Dominator pipe)
In the meantime i'll check out that website for further info.......thanks alot man.
