5.7 Hemi Stroker
Talk with stu at inertia motorsports. He can set you up with everything you need. I have been using him for years. Great guy to work with. And knows the Hemi well. He can get you the parts or ship a built short block if you would rather go that way. HP and TQ will depend on the combo you going to port the heads? Change valves? What compression? Si you want a 370, 383, 392, 400 cubic inch? All this will move around the HP numbers. My motor will be a low compression 370 and should make between 1200-1400 to the wheels on 20-25psi. The motor N/A will probably be about 600HP at the flywheel when done. With the right set up I think you could see close to 700 at the flywheel if you build a full race motor with all the tricks. but that would have to be a really high compression (race gas only) motor with a huge cam and really good flowing 09+ heads.
