Post your 12 second small block combos
'69 340 Stock crank and block.
10:1
.530 lift, .230 degrees at .050
Edelbrock heads
Comp Cams rockers and shafts
RPM intake
Holley 750 HP Street
Car is a '72 Duster - glass hood, rest is steel. Frame connectors, SS springs, Four speed. 93 octane. Drove it 40 miles to the track, raced it with no changes, and drove home.
With 3.55 gears, my best was 12.77. Switched to 3.91 and best was 12.487
Next year, I'm going with a deeper gear for the strip hoping for low 12's.
