Best 273 and 318 builds (NO 360's please)

Sorry to disagree KO, but that result has been established as not just a "happy" Dyno result...but clearly "hysterical".....

I refer you to 71340 post - basically the same as SD and made 70 HP less.

No-one I know of has ever got near that 400 HP result with the same or similar build - and that includes using better heads.
