Yeah this must be at the flywheel, but they don't mention the rods, rockers, pistons, or crank. It got me thinking about 5.7 rods with 1.5 rockers.
So 2 question:
What kind of difference is there between 1.5 roller rockers and flat-tappet?
I'm leaning towards Comp Cams XR288HR. One thing I don't like about this cam is that the RPM Range starts at 2500.
I want something closer to 1600-2000. Is there a better cam?
