427w back from rebuild with dyno results

[Tommy]

I believe that rule of thumb is 10 pounds of air per minute per 100 HP.

What octane is recommended by the builder? What is the compression & cu in?

She calcs out at 10.8:1, 91 octane...The actual Cu in im not sure whatever the overbore is? With a 4" stroke a .02 overbore would add about 4.25 CI if my math is right so ~431 or so?

I was impressed with the numbers, i don't really NEED as much power as possible, just thought it was an interesting stable looking curve, just sharing. Its actually going to need a stouter clutch based on its torque capacity than the one i had...Fun to brag about at cars and coffee will i use it? Not really...

The impetus was to tear the motor down and put it back together right, its burned oil from day 1. I put the ported heads on just because i got a smoking deal on a brand new pair.

Seems Ford Racing uses alot of cool guy bits but falls short on the actual build from what i was told by the builder.

You are correct Tommy.

I failed to include the ever important time dimension. Without the time dimension the metric is of little value. Thanks for the dilligence and heads up.
