Help with 340 compression + cam change

Static and dynamic CR's numbers always hang consistently together with the cranking compression numbers. That 160 psi indicates a DCR of around 8-8.1 and that is not consistent with a low-mid 8's static CR.... not even close with the cam and piston combination posted or even with a cam that has 20 degree shorter duration.

And, the 1/4 miles times don't seem to be up to the potential of the combination....So IMHO something is up with the cam/lifters and the intakes are not open as much as thought....

• the cam listed might not be the actual cam or it is considerably advanced.
• Or deck was milled more......
• and compression gauges can be off.

I'd encourage the OP to do some lift checking/profiling on the cam and try a different compression gauge.
