Yeah i was thinking about that i just thought it was 720HP not WHP

Great info that's exactly what i was looking for!

The pistons are not hugely different but the S54 rods are significanty thinner.


The next step we are taking, is to build the motor with no sleeves and see what the stock block will handle reliably without sleeving. Bossman says he wants to have it built and in the car before end of this year ..

We're probably gonna go with the lower compression pistons on this build since they are around 30grams lighter. Then next motor after this one will be full out race motor and we'll go nuts with it. Right now we just want to see what the stock block will handle without sleeves.
Got it! Im not familiar with mustang dynos that much and when i was looking at the dyno slip it said Engine HP and Engine TQ so thats why i was surprised

Thanks everyone for the explanation and staying professional without bs i appreciate it
