I believe he removed the A/C compressor so I will need to find a way to squeeze that bugger back in between the cooling mods.

A 4.2L you could get away with the CSF radiator and I highly recommend it! Great Product and Great Customer Service!!!

Why does sleeveing the block create so much additional heat? Do you think it was worth it to add the additional .3L given the heat issues that come with it?
