5.7 Swap article

It is always welcome to have new Hemi swap info in print. Very good thing.

However, I am miffed at how the engine they used made so little power on the dyno considering all the hardware it used.

'08 5.7:
Arrington Cam: 223/234 duration@ .050, .595/.589 lift, 114LSA
cnc ported heads with new valves
Mopar single plane intake
unknown CFM Eddy carb that was "dialed in for our 5.7."
TTI Headers

all this only adds up to 437 hp and 371 lb-ft's of torque according to Arringtons dyno. Sounds lacking to me. From what I have seen over the years, this combo should be making near those numbers at the rear wheels, not at the flywheel. With CNC'd heads near 500 hp and 415 lb-ft tq seems more inline with what I have seen.

The XV combo with nearly the same intake makes 438hp with only a cam, intake and headers...

What do you think?


Other than that, its a decent article aside from the typical magazine hype. :D
