LSA or Duration to fine tune glasspacks??

Come on guys. You know better than this.

If you age going to go full baller/tuner and use glass packs, you ought to be using the 1970 LT1 cam with the 116 LSA.

You guys should be in the right era on this stuff.


And to whoever posted the puke face...that **** is just nasty. Looks like he was drunk with the flu
