That cam 248/256 .558/.550 is in my Daytona 2900# without my fat *** in the seat! 10.5:1 and EQ 1.92 heads and victor intake. It will spin to 6K with 32/14.50's and 4.57 gear. Its a little wined at my elevation 4200da at times 6K, but by far the best grind so far. The 242/242/.510 Schneider solid I run in the 360 Dart 3.91:1 26" tire 4spd with 1.94/1.60 308 heads is winded at 5400. the 242/510 is a great all around grind, and both are on 110 Lsa for a little better vacuum at this altitude. Again I loose about 500 rpm struggling with low Da. Both cams are SFT.
