Is this to much cam

I'm thinking about installing a cam in my '86 d 150 with a 318. I am considering this Summit kit. Engine is stock with a performer intake and Holley 600 and duals, what Y'all think?

I'd run that one with the recommended springs and Rhoades lifters to give more low and mid range with more MPG...

That one's barely over a stock 340 cam...
