You may have seen these before but the "sticky" is a great idea
408 Pontiac Jetsprint boat in the International Group A class (412 CID limit)
We are restricted to iron heads / block / valve limits (2.125"/1.770"), 1-11/16" trottle bore carb etc etc.
We run Jim Robertson #48's wacked about 070 with relocated pushrods, offset intake rockers and a whole bunch of his tricks and about 6 months worth of grinding LOL
Engine runs at 5800-6400 during a run for 50-60 seconds depending on the the track
We havnt won a race yet but have been on the podium against the Chevies with there 330cfm Iron Eagle this and Pro Action that heads while we run something made in the 60's / 70's
One is a night time meeting and then a couple if in boat from other meetings
