It's got a fast rate hyd cam in the motor....... So it's not going to rev real high, whether there is potential hp up there or not.
The OP wants to take gear out of it to make it more street friendly, but doesn't want to kill the ET.
With those variables in place, there aren't a lot of options.
The motor should easily make 400hp, if the valvetrain will stay happy high enough in the powerband to let it.
The RPM heads would certainly provide enough flow to facilitate a hp peak of over 6000rpm, but I'm not too confident the lifters will allow that to happen.
Can you elaborate on this a little Dwayne? What do you normally see with these XE cams? Do they start to break up in the higher rpms or what happens exactly?
