I got a little too happy with the 496/265 AFR combo that was in my Camaro. When Scat says 700 HP limit they mean it. Anyway that one is repairable but I'm building a 540 because I know myself and my foot is very heavy. Most of the parts are in so its build time. Yay. Street build for occasional races. I prefer the drag strip dyno to engine or chassis dyno's cause there aint no fooling the number you get from trap speed vs weight. The 496 had 620 HP on the ground . Looking for 700 HP on the ground plus maybe a wee bit more from Nitrous. 10 flat give or take. anyway.... Dart 4.500" block. Mahle 13 CC dome pistons for 10.3:1 ish compression. Scat H beams with 2000 bolts Manley 4.25" forged crank AFR 225's with the 121 CC cnc chamber upgrade straight out of the box The same Straub solid roller I was using in the 496. 264/271 @ .050" net lift in the mid to high .600's off the top of my head. Only running a 950 Holley clone with a vic jr. Great running carb actually but a bit undersized for big power numbers I know. Pretty standard fare for a 540 . Looking for street diveability and brutish reliability above raw HP numbers . And the build begins. Paint is drying right now.
