I saw in the post below you are running the Griffin Rad in your 260Z. What size did you get? Is the core thinner than a stock Z rad? Do you have elect or mechanical fan? I need a new rad and am thinking of going aluminum.
id ave to go and look to take the measurements as im not sure of the exact size but i do know that it is close to the stock rad size... when i told them what i had (guys at summit), and what i neede to keep kool, the griffin is what they suggested and i just gave them the area i had to work with. and well the rest is history. ill go down to the garage to check later its still a bit nipply right now but like i told the other guy its the best 180 i had ever spent. great cooling radiator and it looks fantastic in the engine bay also. i use a pull fan system (eletric).
