Thinking of going a little bigger on my cam with my mods listed in my sig. No other changes. It runs really well right now, definitley don't want a loss of performance. Cam specs 222/228, 567/567, 113lsa. What do think I should expect? Current setup got 353RWHP on HPE's dyno and I drive it daily.

 

any reason for the exhaust bias'd split

 

Just a shelf cam with those specs. Not looking at nitrous or a blower anytime soon.

 

I would leave that 220 in there, 353rwhp is stout.

You would at best gain a few hp/tq, like maybe 5 in the lower rpm. Definitely not worth it IMO.
