PC an ENGINE BLOCK??

[goincrzy]

I have an engine block I wanna PC, I heard that by doing so the engine will run hot cause PC will keep the heat in and the PC will actually hamper the way the block cools. Does anyone know anything about this? Has anyone ever PC a Block and drove the car around for awhile THanks

Well i have! remember ur PC just the outside, not the internals, the engine cools itself with the water running trough it not with the heat exiting the metal itself by the block. I did a rotary 13b and its pulling over 500 whp torbocharged and still no temp issues (and i live in Puerto Rico with an ave temp of 90 deg F)
the engine PC'ed
