Need help with Insane 340 setup.

Ouch 11.5 to 1 pistons on pump gas. You got some nice pieces though. Econo W2 rockers, pedestals, titanium retainers, Mopar performance sold the same TRW pistons a long time ago. You have to figure if your going to run the same pistons you will need race gas or cut them down and rebalance the crank.
