Correct forum section......maybe I'll get some guesses.
408ci LQ9
9:1 compression
LS1 (241) ported heads (they flow 304cfm)
LS6 intake and stock ported TB
cam will be whatever I'll be using for the turbo set-up
My 4L60E for now.
N/A RWHP guess????
On a 150 shot????
Just curious, might have to run it for a little while till my friend can build my single turbo kit. When I get the turbo set-up going I'll get AFR heads and a different TB.
Hope it won't be a total dog N/A.......lol

Yeah I'm the same boat as you. Just finishing up my turbo 408 motor and trans and just cant get the turbo on yet. I'll be driving it N/A this summer. Mine should be in and tuned in 2 weeks if the trans ever gets here. i was hoping for Mid 400s, but well see. Post up what you end up making and I'll do the same.
My build
408 9.7-10:1 compression for E85 with the turbo
TFS 220 heads
Big Cam (For a Turbo Motor)
FAST 90/90
1 3/4'' headers with 3'' true duals
4L80e
9'' rear

Yeah i know the feeling. My h/c 347 was 470 to the tires on a mustang dyno. Now ive spent all this $$$ on a 408 and 4l80e with that low gear... Going to feel a little sluggish. O well it'll all change when the turbo goes on. Goodluck to ya.

Wondering if you ever got any dyno numbers on the 408 you built for boost? Just got mine off the rollers and it put down 463rwhp. Dont remember what the torque was. Basically what I expected for whats done to it and having a 4l80e and 9"

Yeah the 463 was the n/a number. Motor is built for boost. Still havent gotten the build sheet yet, but the compresson is between 9:8-10:1. After the tuner got done with the car he thinks i could even run 93 octane even though I had planned on E85, which is why i chose around 10:1 compression as it is mainly a street car and i didnt want it to be sluggish out of boost
