Mine is a 416 W2's ported by Ryan J. TTI's, 4400 TA, 4:30's. The cam which is probably too big is 272@.050 on a 108 CL and the compression is 11.2. It runs fine on 93 octane. I am currently using an old 750 dp carb. Car weighs 3500 on CAT certified scales. My street tires are 29.5 tall.I can cruise a 60 at 3200/3300 rpm. Car has unbelievable torque. Unlike some here mine wants more than 6500 rpm's. Probably cam related. It runs 12.0 if you shift at 6000. 11.8's shift at 6500. 11.6's shift at 7000. And it has seen 7500 a couple of times. I will say it was still pulling hard at 7500. I will probably change the cam at some point in the future as I don't want to turn it 7500 to get the most from it. I would never run a mechanical roller on the street again. The rollers just won't last vety long. I have tried it in the past and had roller failure twice after 15000 miles. Just my experiences.
