Thanks All.
It is the original TBSS we built a few years ago(427 LSX with All pro heads, th400). Its been put away for a few years, and we decided to bring it back out and up the shot a little.
We removed the exhaust from it, and gave it a new tune. We netted 689 rwhp on motor. The full exhaust was holding it back a few.
I then put 250 jets on both kits. So we are spraying a 500 hit
We had some bad luck at the track though. The fuel regulator on the second kit stuck. It went lean and wiped out a few valves.
We just got the heads back and are getting it put back together. Hopefully we can run mid 8's in the 1/4.
