You are throwing a pork chop past a hungry wolf..
I would love to have a hydraulic roller like that with the 3.00's and all of that torque down low. My 394 makes about the same amount of HP, and 40 less lbs ft of torque and it has to be 5500-6400 to really ring. I did a lot of fancy work on the short side of those C4AE-G's to get that, along with a really bitchin' single plane and a downleg 750 "780". Being a solid with the galleys blocked, I'll have to run 3.70's, and get about 5 mpg.
