First question - Desktop Dyno says 478hp @ 6000-6500rpm, 454 ft/lb @ 5000rpm. does this sound correct?

Second question - Will the stock block, crank & rods live long making that kind of power? (I've heard that 400 is about as much as you want to do.)

Third question - What kind of ET/MPH?

Fourth question - When you are looking for 400HP and get 475HP is that a good thing? LOL

Can you make a desktop dyno run for me??

my question to you is what kind of head are you going to run? and imoho i would run an edelbrock intake, just going with experience, they usually work great, the rpm intake for you.

engine analyzer to your right will give you guestimates on 1/4 mile times
