Need help building 416 Stroker!

I build my 416 with a Scat Kit with forged dish Pistons and RHS Indy Heads and have compression about 10:1.
Add a Lunati 03 hydraulic Cam 268° .494 intake and .513 ex,
Ede Airgap, 650 Holley 4011 DP, TTi stepheadders.
Very streetable and loads of torque! Runs pretty smooth.
Have with a 4-speed and 2.91 gears in the back no traction up to 3. gear!

Awesome setup!
