Hotcam and programming I am installing a LT4 hotcam kit in a 94 Z-28 and i was wondering if anyone knows if I can use my stock torque convertor, I know a stall will be much better but I would like to run my stock torque for now. Also I am going to have my processor reprogrammed soon and does anyone know if the stock processor with a LT4 knock module will work for a while.

If the person that programs your PCM has a clue as to what they are doing, you won't need to buy an LT4 knock module. That is just a band-aid to cover up other issues.
Good luck, Ed
It will run with the stock programming, but I don't recommend that. Reprogramming is relatively inexpensive and should be considered required for a modified car otherwise you are leaving a signifigant amount of the power you should have gained on the table. A local put a bigger cam in his 97 with no programming, then we met and I convinced him to let me load something close to what he needed in an OBD1 pcm and plug it in. He was so impressed he went straight home and ordered proper custom programming.

Get the reprogramming doen as soon as possible. Mine sucked through a tank of gas in 60 miles of street driving when I first got it in. MY cpu could not cope with the Hotcam. Once it was programmed though, it was back to normal, getting 240 miles per tank.
