408 Stock L92 port CTSV retune... 231/235 LSK RESULTS ARE IN..
A/F was a bit off from our previous 2:00 a.m. tune and it took 3' more timing. I guess flopping input shaft's are a bad thing.
497 rwhp 481 rwt
5,900 rpm 4,600 rpm
It makes 395 rwt @ 2,600 rpm, 445 rwt @3,000 and peaks 481rwt @ 4,600.
I'll try and get a dyno sheet up shortly.
Stock port L92 heads, 11 to 1 C.R.

J dog booyyyyyyyyeee,
Thanks, I may step the cam up a touch, maintain idle vac, just moves things around a bit. I think there is well over 500 rwhp, with anther 200 or 300 rpm up top to peak at. This thing peaks at 5,875 now and just carries the power to 6,200 +. I'll be back on the dyno shortly, I have extra L76 intake I'm porting a bit to see what happens. Mild restriction in there I believe.
Vette motor is out, 439" LS7 going together, 33' of overlap this time
with 13.5 to 1. I'm looking for 625 rwhp at a min. NA. My E.T. streets are going to become dailly drivers on this thing.
