Feel like my 440 should be faster

So, L2355 pistons…….flat top 4 valve reliefs?

Looks like 9.38 is “close”, at worst.
That sounds like them. I spoke with Howard’s about the CR and they said this cam would be a great fit with my setup.

Just put this motor together, at this point I’m not changing heads, converter, cam, etc… is what it is. I’ll do some different gears this winter and just enjoy it from there.
