I always considered bravo1 props stern lifting and mirages bow lifting.

BT

I think his point is that within the world of 4-blade props, the Bravo 1 is on the "bow-lifting" side of the spectrum, as opposed to Hydromotive's Quad IV.

ok... so does anyone have a desktop dyno.. or familiar enough to give some type of hp and torque for this engine ?

Don

am i missing something or does that 651 cam and some of the specs i'm looking at without some of the compression ration look like this motor from GM... i thought this combo would make more hp

I could run numbers for you. Provide airflow numbers for every .100" lift in/exh and cam specs along with all other engine vitals.

Blue Thunder,

What other specs do you need other than what I have already posted..

Thanks
Don

With a set of cnc AFR's or Canfields and a larger carb would work wonders. The heads on the crate motor sound like the same ones on the 502/502.

Heads on the ZZ502/502 are same size valves but oval ports with 110cc combustion chambers.

I assumed the difference was in the head... but it doesn't make sense to me why GM would choke that engine that way, when they seem to do so well with the ZZ 502/502...

Don

This build is more similar to what you are doing, 38 less cid, 700+ hp, closer to your Canfield heads, similar cam, and notice the compression ratio.
700+ HP 534 cid Pump Gas
