![]() I recently rebuilt a 351-C for our 82 GT. The machinist who I have a great deal of respect for recommended not going over 5800 rpm with the stock Cleveland valves and keepers. These are the ones with the multi-groove valve/keepers. His reasoning is that he's had only one customer who races a Cleveland and he takes his to 5800 with no problems so far. Has anyone had any high rpm experience with the stock valvetrain? I ask because we've had it to 5200 and it's still pulling HARD when we shift there. The cam specs show it to be good till just past 6000. It just seems a shame to waste free horsepower and those huge ports.
