the power you get out of a ZVH by large depends upon the management and boost you are running,

The engine make little sence to me, I fail to understand why FWD people think its a great idea to pull off a decent 16v head and replace it with a 8v head which flows less.
You don't get the cossie boys pulling the 16v head of the YB to replace with the SOHC from a 2.0 pinto do you
