422 dyno fail

To me, the cam is ultra suspect. I won’t run anything smaller than 260@50 on a 4 inch motor. 240 hyd roller is a very bad selection and is killing power. I would bet on it.
I also don’t like leaving compression on the table. Bumping up compression and camshaft would be the two things I would do with this combo before I started swapping bolt on parts on an off

I definitely think there is more power to be had in the cam. With a 9.5:1 engine I was looking for power out of i'd be looking for a tighter LSA/LCA. And I might see how how it responds to being advanced as well if the valve clearance was there to do so. This effe3ctively would raise your compression ratio by increasing cylinder pressure. I don't think [email protected] is too small, but more duration would help overcome the head flow restriction. I'd also be running a solid roller. There is no reason not to.
