So what will probably break when HP rises?

So a set of new 7260 universals on the drive shaft... The traction is already an issue with the little 340. Have a set of M&H 275/60 drag radials coming which are that will fit in the stock wheel well / spring location - if they fit at all.

Missed a built 727 with the stroker as it had been stolen by a tranny shop that Mackin had left it at for a refresh. rats. Left the 4sp and all the parts to mount the pdeals with Mackin as I am staying with the auto and maybe whomever buys his car may want to make it a 4sp.
