I changed my home ported edelbrock heads on my 410 to trick flows but also changed my cam. Went from a hughes 234/238 @ 50 with 530? lift on a 110 lobe sep to a custom Howards 237/243 @ 50 with 610 lift and 112 lobe sep. used to make 392rwhp ,now makes 425rwhp. Revs were all done by 5800 before but now revs cleanly to 6400.Car behaves much nicer with this cam and almost feels like I have put a smaller cam in it. Last time at the track I ran 11.5 @119 mph but have not been to the track with this set up yet but it feels faster on the road as it revs real clean now and brakes into wheelspin any time you nail it in second gear(5 speed manual)
