I bought this converter from PTC "for" the High Port engine back in 2016 but ran it in the old 455 HO.
The only specs that was different in the info PTC got back then was 10.8-1 CR vs the 11.5 that it is today. And the cam was to be a Crower cam Dan spec,ed for me, 270-275 .404 lobes on a 108 vs the 265-274 .431 lobe 112 cam that in it now.
It worked great in the old 455. Had them loosen it up just a little bit and we will see how it does.
