7 " vs 8 " converter?

[danny waters sr]

Thanks for the comments. I plan on putting the 8" in it when i get back from Fla. I will let you know what it does. I also am thinking of getting a little tighter 7". I don't really want ot send my 7" back to play with it ,. If i do that i may lose what i have got already .It just seems to me it should have at least around high 1.50's or very low 1.60's.
