Is it for a 305 a 292h can be a really big cam on the small bore engines. It may also have way too much overlap for most turbo apps.
I love big cams but for small engine its not going to make any power under 3k rpm. Then it will only come alive long enough to run out of flow.
Why 58 cc on a turbo motor. A 2.02 valve head with large chambers would be better. You can always turn up the boost its hard to turn down the compression.
Race car/street car?
