when Rob brought it up i told him what ive heard in some other forums
when doing the 686 kit upgrade,and reusing the stock con rod,some were experiancing con rod failure,,in other words getting a close look at there piston as its coming out of the engine
i seen several discussions on this subject,and the fellas that had failed con rods strongly suggested a more substantial aftermarket replacement,and adding they wish they had due to the cost of a new con rod verses a new complete top end,and a stressed,or damaged lower end for a kicker
i still think with a decent high compression piston,and a cam could produce some decent HP gains,all the while being of considerable savings to the wallet,and labor
