You would be better off to run the 51-221-4 .
It would keep your dynamic CR down enough to run 87 In My Honest Opinion.
It is about the biggest you can run with catt wizz gas,tall gears, stock converter and 350 cubes .
Bigger cubic inches need bigger cams. Dont over do it on cam choice.
I agonized over my cam choice for almost 9 months before I finally chose th exact one. I had originally 3 different ones in mind.
Fact is stranger than Fiction
