Default DCR Calculator

We've updated our DCR calculator to calculate the DCR at each IVC degree from 40 - 100 degrees ABDC. This way you enter the hard parts information, find the desired DCR, and see the IVC close point you need. This will make it easier to find the cam you're looking for.

Here's a sample output based on a stock LS1.

Code:
You Entered:
Bore 3.898 (inches)
Stroke 3.622 (inches)
Rod Length 6.098 (inches)
Cyl. Head Vol. 66.67 (cc)
Deck Height -0.008 (inches)
Head Gasket Bore 3.91 (inches)
Head Gasket Thickness 0.054 (inches)
Piston to Cyl. Wall Clearance 0.003 (inches)
Top Ring Land Height 0.2 (inches)
Piston Dome Vol. 0 (cc)

Compression Ratio:
10.349 : 1

Displacement:
345.8(ci), 5.7 (liters)

Bore / Stroke Ratio:
1.076 : 1

Rod / Stroke Ratio:
1.684 : 1
