Yes a c6 will hold 500 hp but not a stock one with 3 high gear clutches or a stock valvebody…. A good upgrade is to remove the wave washer from the forward clutch and fit 5 plates,upgrade the high gear clutch to at least 4 but 5 is better and go with a transgo valvebody kit…

Will a C6 transmission bolt a 302?
Premium Member. The C6 will physically bolt onto either the 289 or 302 but I don’t think it will fit the 66 tunnel without some modification to the tunnel. It should fit the 68 tunnel fine, since a big block with a C6 was available that year.
