Those numbers are not bad at all. See what it runs at the track, dynos are for tuning and far too many people get caught up with the # game.. 58mm on that set up could affect your numbers in a negative manner I would put a stock 48mm TB on and dyno again.

Head milling doesn't mean much. If they were actually ported then yes but a head mill tells me they were removed possibly due to a blown head gasket.
The numbers do seem a bit on the low side but I agree with the above. See what it does at the track.

OP, My setup is similar to yours and I've run a best mph of 107.93 at Union Grove with the hotcam, slp headers, LPE cai and stock rocker arms with a Madtuner tune. 120k miles. If spring ever shows up bring it up to GLD during the week for T&T and see how she does.
edit: If you're running the LT4 valve springs you might consider changing them. I was getting some valve float with the LT4 springs on the hotcam, swapped them out for some stronger springs and she revs much better now. Any signs of valve float on your dyno run?

What do you think it should be at if they seem a bit low to you..,?
probably a 12" which would be a really bad choice, being that heavy and that high a stall it would likely hurt dyno numbers a lot.
I will agree though, make some passes and see what you come up with.

I will when ever it get Warmer here.. I just wanted to know if people that have similar set ups what are they putting down to the wheels cause those numbers seemed low to me
IIRC LT4 hotcam only auto cars with good mods were in the 12.4 @ 108 range with everything the OP has including good track conditions. Don't know what that equates to on a dyno.
