Re: 3 blade to a 4 blade prop
 

I can get my hands on 21 pitch 3 blades. Would that work better yet?

Re: 3 blade to a 4 blade prop
 

21 pitch props will work better than your 22's for what you want to do with your boat.

We got a good deal for a nice used set of 20's 3 blade installed. Since we will be running higher rpm's is there anything I should consider adding? is one of those Holley 500 cfm worth adding or just keep it the same (though I'll probably rebuild it)? it currently has a the 2 barrel rochester on the 5.7L. thx

No the prop change should be fine. Switching over to a 4bbl will only use more fuel.

I agree, I was thinking of the holley 500 cfm 2 barrell though. I think the rochester is probaly 250 - 300 cfm.

Leave it alone and go have fun!
That will work great for the "play" mode your looking for.
Just don't let her go above 5 grand , and you'll be fine.:wink_thumbup:
