An update on the 5.7 hemi motor. I just looked at the 2007 5.7 hemi in the engine specs on the NHRA site. The specs are not complete but it shows 10.5 to 1 compression, 2.00/ 1.55 valves, cam lift 482/ 470 and a hp rating of 345. I know this motor doesn't have an intake or throttle body like the crate motor and it's 40 hp more.
