could my truck handle the smarty on sw #6?
or would i be better off with the jr on sw #3?

 

Well, the Jr on #3 is 100 HP, the Sr on #6 is 130 HP. I think you will be pushing it with a stock clutch/or automatic trans on either level, especially with those 305's and planned 37's.

For the money I'd grab the Jr for now, if you want to get the Sr later I'm sure you'll have no problems selling the Jr.

 

Sr..... Once you feel the power you'll keep wanting more trust me... ANd rolling 37's you'll need more... You will definately need an upgraded tranny or clutch!!

 

Couple of hundred extra pays for future expandability.....so it depends how dear that $ amount is to you.
