I'd would say: "I havent used that Lunati cam, but it looks like a suitable choice for the direction you’re trying to go. I also agree that for operating range you’re running the motor in, 200/500 springs loads should be plenty." is a pretty good indication that Dwayne is thinking like I am, using the tighter LSA/duration to target a specific RPM. Granted the 2.25" exhaust seems a lot for 4500 rpm, but I'm left that up to the SMEs of Hi-Tek marine, as their test results seem legit.

I'm hoping to get some feedback with that cam concerning EFI, as LSAs of 112-114 typically works better with the traditional speed density and MAF setups, but the Holley HP system seems to work well with 108-110 LSA cams...my motor purrs nicely from 700-900 with a 13.5 idle target AFR. https://youtu.be/OruBFxQwC6k
