the octane in my country is 95 or 93 i guess is that enough? I will be using the stock aluminum radiator and the stock fans that comes in 92 Z28's I might switch to single large fan

Well, i had a 383 with a bigger cam, bigger heads, same compression and stock radiator with a 112 LSA, i had no issues at all driving it all the time. I had one upside to you, a standard trans, made my brakes work pretty well. You will be happy with it and i even had a 383 with cast iron heads and that same cam shaft and it did verry well.

well thats good to hear because I was thinking of changing the head gasket to a thicker one and before two days ago I was like why I dont run the engine with the same gasket and everything the previous owner was using the engine and the tempreture was 180 without any thermostat so I guess I will be fine with 160 thermostat and high cfm dual fans

My setup is similar to that with iron heads and I can run fine on pump gas in cool temps and sometimes in the heat. I do have a large radiator and my electric fan is always on, like said above quench is important though.

capn smokey I dont think I will open the heads to check the quench the previous owner of the engine just installed everything without doing any machine work on the heads
