Hello all, i am trying to decide between the two cams listed below. One is the XE274 and the other is the XE274 High Lift version. Which one would be better for my application? I am building a 383 stroker (450) with 440 source heads, Holley street dominator intake. Its a 4 speed manual trans with 3:23 gears out back. Any advice would be great, thanks!
