***biggest numbers out of twin s366's***
Im halfway through a similar build. Lq9 403ci 11.5:1 comp ls3 heads twin s366 and a powerglide. Plan on pushing 20-22 psi. Maybe more if it feels strong
Only dynod it once 14psi made 685whp
I run 26psi at the track, and has pushed 3250 lbs to 161 mph. My combo is not an optimized race car.
The fastest guy I know that used them was Seth temple, he works for bw air werks and ran low 5s at 140+ in the eighth.
