Has the motor been dynoed??
fordracing65 You have a couple of simple questions to answer,
Is the crank crankshaft and rods cast for forged??
What is the max power range of the camshaft? REV range?
Why are you looking for 7,000 rpms?
Are you running an aftermarket block with crankshaft support for caps?
The old rule of thumb is 3-500 rpms pass max hp tops out.
Here's the key question, if you are going to beat on a motor this hard you better know that it is possible for it to break and parts to come visit you in the drivers compartment. Unless you are in a titanium tub like an "A-10" you could get hurt for pushing this motor past a safe red line. What is the matter with a 6,200 rpm limit?? If you are looking to go faster speed, lower the rearend ratio. This will help lower the revs on the motor and extend the life of it. Rick L.
