it rumbles good, but it roars even better. From what the plugs say it is lean an wide open but it is SUPER rich at cruise and light throttle. even after getting the correct power valve in it. Its only a 318 but it seems like it wants more than the 75 jet in the secondaries i have in it.
but once I figure that out it'll be the fastest damn thing out of my little friend group. (all chevys) :D
