Dan, Thanks for the input. My dad and I had the pleasure of talking to you at the POCI nats in Moline IL(1996) when you had your 71 455 HO Lemans 3 speed (beautiful car, by the way). You have/had quite a nice collection. My dad has a 72 455HO T/A and its been built some. A little port work on the 7F6's, gasket matched, about 9.5:1 compression, a tuned 71 HO Q-jet, Nunzi 068 profile high lift cam as well as the basic rebuild on the block. I have a 76 T/A that is a 455 4 speed. I have ported 4X's, 1.77 valves, RA III exhaust manifolds and the 068 Nunzi cam. My winter projects are to install the 72 HO aluminum intake, 71 455HO Q-jet, Nunzi 744 profile cam and 1.6 full roller rockers. As the set-ups sit, they are dead even. I am hoping to gain a little with the 71 HO carb and 72 intake. What are your comments or opinions on those two particular items? I saw you on MCC and read in MCR, my compliments to you and Bob. One question in general, I have read much about the difference between the 197 and 7F6 heads. I know the 197 is supposed to flow better, but what is the real world difference (performance) between the heads? I have considered getting into round ports, but I am happy with my d-ports. No use spending some big bucks on a pair of round ports for little if any gain. Thanks again Dan, I hope I am not asking to many questions. Rocky
