.458 BFSC at 6800 rpm for an NA non Diesel engine is incredible! Spark plugs are dead on.

Nice build there Darby. 650 to 750 at a higher RPM I assume. What else are you changing when this motor goes in?

Peaked 100 Rpm sooner then old motor, torque was actually 1-200 higher on this bigger motor, Lenny has my numbers for the conv change. I've changed a lot on the car to help with added power I added sub frame connectors, and lost some weight to offset the added weight of the block!! It may end up a tad lighter well see.

That 666 max torque with the .6 added on might scare him at night too.

It is nice to see a dyno sheet without a huge correction factor for a chance!

Kinda what I found out too. I thought my new engine would need a completely different converter. Called Lane at PTC and he told me a re-stall was all I needed.
