Motor is running great mainly with the help of a buddy fixing my screw ups tuning. Taking her to the dyno tomorrow night to see how close I can get the tune..
seems alittle low even with a th400 and the ls6 intake but track times will tell with a sea level correction factor. with a good intake setup that motor should clear 600 fwhp so 425-450 rw through that driveline should be doable.
425-450rwhp through a Dana 60 and TH400 is a respectable number. Keep in mind you have an LS6 intake, 1 3/4 Headers and a stock cat-back with a Flowmaster muffler. Once you get those swapped I'm betting you will be right on par with where you need to be.

Get some jessel rocker arms on there also to free up some Hp, add a fast 102 and 102mm tb and 1 7/8 headers into a 3" exhaust and you'll be making some power. I have about the exact same motor but with the mods i listed to add to yours. Also putting on a vacuum pump to help out a little. Haven't had it on the dyno yet but it sure does make a lot of power and pulls really hard. What lifters do you have in there? I went with some comp cams short travel race link bar lifters and TEA TFS 235cc with nitrous exhaust port. Did a custom spec cam for my setup also. I'm running mine through 4l65 and yank ss3600 and 3.91 gears on a spool. Good luck and enjoy the fun.
I would do the fast but that's just me. Once you get the exhaust on and a fast on it will pick up a bunch I am sure. Do you plan on going to the track to see what it traps as it sits now?
Yea I won't be able to make it to the track prior to upgrading the exhaust. But maybe before the intake... I know I'm trapping slower than 112 mph because my buddies Ctsv traps 112 and he pulls me hard on the top end... I'm doing the true duals tonight and hopefully it will pick up some power... I'm putting it back on the same dyno in about a week or 2 to see how much I gained after dual exhaust.
After looking at Ur logs u posted u might want to fix Ur knock issue.... And no way a car that traps 112 should pull u.. u should trap anywhere between 120-126 in the 1/4..112 trap is for a Bolton ls1 in a fbody
You do a compression test? Also check all the primaries to make sure they are hot.
I would do a compression test, leak down test, and check all the primaries and go from there
keep in mind people that at high altitude where i live a bolt on ls1 traps around 100mph, as far as the knock issue... the very next run i dialed back the timing another 2 degrees and the knock went away...
