9" is stout for sure
Then again ... it weighs more than the 8.8
Nice thing about the 9" is you can quickly swap out the punkin
and you got a different ratio
Another thing about going 9" is you will have to deal with
modifying it or buying one already setup to fit your Stang
I gotta tell ya ..... Them 9 inchers are tough
I used to do full on launches at strips all stuck up with VHT
at 5 to 6K with wrinkle wall slicks and never broke nuthin
