A few cr ratios for the 5cc domed 4.8/5.3 and 5.7 pistons

5cc dome 3.780 bore stock head gasket stock 706/862 heads 4.8 stroke
9.94:1

3.820 bore (.040 over)
10.1:1

Add in our rpmspeed head gaskets ar .045 thick and add .2 (2 tenths) to each of those.

For a 5.3l they would be
3.780 10.9:1
3.820 11.1:1

.045 gasket add .2

For the ls1 or 3.898 bore iron blocks
10cc dome 66cc 853/241
11.69:1 with stock head gasket

243/799 heads
12.0:1

They are also available in 3.905

Talk about true budget builds.
Some food for thought during tax return time that wont break the bank.
