? do you use a stouter piston? travel is pretty much constant as far as I know due to clearance issues....can you explain? Love to know.

the longrod 302's have been shown time and time again to be no different than a 4.0 bore, 3.0 stroke 302. The theory long ago was a tad more dwell time on compression with the long rod. As for as rpm that is limited by cam, head and valvetrain, nothing to do with the longrod. As for plugs, use an autolite 24 and go from there.
