Fuhrmann, just caught the question you asked a couple of posts ago, sorry. I like the 3:42s, I would have gone a bit larger if I had planned to put the TKO 600 in, but a the time I was planning on a built T400 so no overdrive. I bet you'll like the 3:55s, although the 3:42s are great. I finally got a chance yesterday to take it out an bang the gears on a nice secluded street, and I was not left wanting.
TOHcan, I'm going to leave the cam as it is now, but will make a change when I get back from overseas at the same time I go to fuel injection. Here's some more info on my setup, maybe you can recommend a cam for me. The heads were mildly ported by Dave Bisschop at SD Performance. They're his 240cfm package, not sure the specifics, but I think I've got the sheets at home if it helps. Also the intake, nor exhaust manifolds have been matched to the heads, so they are unaltered. When I go to the EFI, I'll be swapping to a Torker II manifold (EFI ready), and I may port match them if that would be advantageous. Thoughts?
