Dynamic Compression
Hi all,
Can anyone give me a hand with calculating dynamic compression?
Looking at a 4.00"stroke, 6.125" rod length, and 1.110" piston compression height. With a stock ls1 block deck height that puts the pistons .005" inside the bore.
Cam specs are as follows:
.248/.254 .615/.622 111LSA
Piston options are +5cc or -3cc with a .040" head gasket and 243/799 heads milled .005"
Also, running 93 octane here so any advice/experience is appreciated.*
Shooting for a half mile race.
Considering the following:
Decking the block .010" for quench
Direct port nitrous
Thanks!

Do a search, there are tools on line to help estimate. This may not be the best I just wanted to show an example.
