I think it's pretty neat this thing is gonna' have cathedral ports on it...
It was good to hear from you today...I knew I'd' seen that short block somewhere, that new # threw me for a loop.
After delivery of the car and a retune on the previous combo made a 435hp/413 tq at the rear wheels on a hurt shockblock. The combo on top of the LS2 shortblock was a LS3 intake, LS3 heads, and BTR 229/244 cam. This combo was ran with the kooks true dual exhaust before we sold the exhaust on the car.

That combo was definitely hurt and that exhaust was a choker. That combo should've been good for about 475/445 with them heavy wheels, stock heads and stock intake.

The kooks exhaust wasnt the choker. The exhaust flowed well. The shortblock itself WAS hurt. Faulty rings etc...
Now the block is fresh with JE pistons along with some H beam rods.
11.5 compression suggest you want to keep it pump gas friendly so losing the weight gonna be the key to reaching low 10's. That and puitting your foot off in its a_ _ with some power shifting and never lifting.

We go lose some weight on the car etc. K member etc
Ive seen a sbe LS1 run 11.33 @ 124 mph with Fast 102/102, ported 799s with a LS7 clutch on heavish Racestar wheels 17/15s. Formula car. BTR stage 3 cam. Good suspension. 11.33 at 124 on 1.6 60ft....
I could only wonder how much faster that car would be on lighter wheels and a better clutch 🤔
I turned right around and saw a M6 camaro, 408ci with PRC ported L92 heads, L76 intake, 238/254 cam go 11.4 @ 121 mph (1.5 60ft) on Weld RTS wheels. BmR k member etc. Good suspension. This guy was so dissapointed in the 408ci build that he sold the car after trying to get a number out of it.
On paper the 408ci is supposed to stomp the LS1 car but thats not the case.
Moral of the story is cubic inches is something but its not everything.

I get that... My car with an LSX427 weighing in at 3840 with me in it and I ran an 11.8 at 125 mph to beat my buddies 468 BBC. I did this on a 28x10.5 slick without even doing a burnout and as a result it totally spun on the hit. My 60 was crap and had me at the 60, the 330 and the 1/8 but by 1000 feet I blew right past him. I have it on video and what I needed to do was make the burnout, launch the car at about 4000 rpm then pedal to the floor, be stellar on the shift and do not lift. From watching the video I feel the suspension needs improvement.
Car set-up and making it work has as much to do with making a good pass at the track and making those record setting numbers as rwhp does! My car works and it took a while to get it there. Hundreds of passes tweaking the car not the engine. These last posts comparing an ls1 car to a 408 just proves that.
The video and timeslip is there to see and I did not launch the car with a lot of rpms. I forgot to turn the ASR off during the burnout and was gonna do it over but ran it anyway.

Either way you didn't make a good pass. Further backs up my point. Hard to compare different cars by e.t. when there are to many variables that can affect it especially in a manual car.
Well today we got numbers out the combo. Not only did the car make great power the torque curve is very smooth. Special thanks to ZZRacer and Jon for making the car what it is today. Its go be a blast to drive after a couple more mods. Remember guys im running a factory water pump, a heavy flywheel and not running a underdrive pulley. The whole time during the build... ZZ would the car is go be a torquey combo. His words are true. Almost forgot to mention that ZZ dyno is probably one of the stingiest ones on the east coast.
