Lqs6293 = 500hp?
I decided to put some CNC ported LS6 heads on my LQ9. So, what does the motor become? Most 6 liters with 243 heads are LS2. But, mine has an iron block. So it is an LQ-2? or how about an LS-9? Or, is it a LQS-69? Since the heads are ported, they flow like LS3 heads. The only logical thing to do is to pay homage to all of them. How about LQS-9623?
On a serious note, the cam is 222/224 .566/.568 on 112. The compression is 10.88:1. The car is carbureted with a 750 Pro Systems carb. I am thinking it will make 500Hp at the crank. The car is 3370 and 3550 with me in it. 3.90 gears and a 3000 Circle D. Anyone have any timeslip predictions?

Finally got that oil-pan you were waiting for huh speed ?????????
Recently seen an LS3(376cid) crate dyno @ 483 stock w/ dyno exhaust
carb and no acessories. Then G.M. cnc heads went 492 hp and lastly
a comp 224/230 stick @ 560 ponies. Even uncorrected w/belt driven crap
thats still 520ish. So w/ 12 less cubes your expectations are realistic
and I'm sayin with good drag radials or slicks you should expect at least
11.70-11.85 @ 115mph

I don't see this car being nearly as strong as your 383. You had more cubes and more cam. Whatever it ends up producing will be measured at the track. I don't plan on going to the chassis dyno.
The engine has an Edelbrock Performer RPM and a Pro Systems Holley DP. I think they said it flows a little over 780cfm.
