fast 90, is it worth the $$ on a H/C car.
Or do you think these 5.3's and this cam will produce nics #'s.
I think these heads have 61cc chambers and 1.5 port job, cc 987 springs, I'm not sure about the valves but I can tell either the int or exh have bigger ones in it.
The heads and cam are older versions.
Who should I have port the int to match the heads. It would be a pain to ship it all to someone but if its worth it!!!
