I would be more concerned about consistency between cylinders. Cranking pressure will depend on cam design and compression ratio. You can have 14-1 pistons and a ton of cam duration and the cranking compression will be low. Properly matching the components will result in the best combination. Don't know much about your combo, but 180-200 psi is very good.




Yep.... I have 14.1:1 and only have 175 cranking compression
mainly due to the 112 lsa... but my engine never
see's lower than 5600 and thats the launch rpm
