You should smoke a 13/16 straight blade.

 

[Goose]

so i will probly just spin that prop and cavitate?

 

[Mile9c1]

Which mods do you currently have? A 13/16 straight blade would get smoked by a good superstock setup (which is what you described above).

above is the motor im building gonna have an msd enhansor for the begining of the year than switch to total loss in a few months

 

[Mile9c1]

Well you might as well try the impeller you have now, but if I were you I'd keep my eyes open for a better one.

It should work fine, however there are better impeller designs out there that may improve hood up over the straight blade. I think the 13/16 sounds good and if you cavitate it should be minimal......you are not going to sit an spin by any means
