Southwest speed sells a Chevy race radiator for around 100 bucks (used to be off flea bay) and its a 3" dual pass that is actually made for them by griffin.
That would be a great start... you WILL have to weld in your own rad mounts.
I forget the dimensions.. but measure the stock rad.. they sell one thats really close just thicker and dual pass.

prolly.. not sure of the specifics, but if you are not getting a Koyo replacement or something similar.. you should be fine.

If you do a lot of stop and go around town driving, then make sure to have a good fan on it. Like a SPAL pusher in front of the rad, or something similar with high CFM.

Do they make Koyo for N/A? I was told at the parts store they didn't Sorry didn't hit search and feel like I might get flamed for this.
