I'm building a 351W with h/c/i and it's going to have around 11.5:1 compression...looking at a custom cam one reason so he can make sure it will be runnable on 92 octane pump gas without ignition or detonating (iron heads also). Im sure tons of people have had good experiences with some some grinders but has anyone have any bad experiences with anyone so I know not to go with them? Anyone better than another? I was thinking about Jay Allen or Comp cams....leave your comments Thanks :SNSign:
