Default 5.3 Twin S371s

Forged 5.3
LJMS TT Stage 1 cam(probably going bigger shortly)
TFS 220 Heads/CA625 head studs
Twin S371s
TH400/PTC Convertor/3.08 gears
417 Motorsports 2000hp Intercooler
Holley EFI/160lb injectors
E85/Cable Driven Fuel Pump

This was on 25lbs with pretty low timing had to cut it short had a leak with the A2W pump. I will do some more pulls shortly was planning on running this into the 12xx range which if it keeps up with current gains per PSI should be 32ish psi and then get it to the track.

Nobody really makes a cowl for a 4 eye that is high enough I was going to cut the feather lite hood I have or switch to a aero front end.

LJMS TT Stage 1 Cam - 222/231 .602"/.598" 112+4 I had it kicking around from when I was going to do a SBE build.

I will probably change it out to something bigger at some point for more RPM
