Need help from all you performance gurus. I recently installed a chevy 400 bored to a 406 and it doesn't seem to have the power it should. It wont even spin the tires. WHAT AM I missing? WHY DON'T i HAVE ANY POWER DOWN LOW? below are the specs.
406 stock bottom end around 9.5 comp ratio
Lunati street master cam 276/286 adv 221/230 @.050 454/454 lift lsa112 RPM Range 1000-5800
Vortec heads
RPM Intake
Street Avenger 670
MSD Billet Dizzy, MSD box, re-curve kit 16deg stop bushng with the lightest springs timing set at 35deg total all in by 2500rpm
th350 shift kit
2000-2200 torque converter
3:73 diff
tires 255/60/15
Car 1978 Cutlass salon 3450lb (about 200 miles since rebuild)
What am I missing, are my expectation to high?
