I put MSD wires on my car only because for some reason the whole state of Michigan ran out of stockers Personally I don't think wires will ever give you any power gains unless maybe half of the ones you replaced were rotted through or burnt. http://www.southfloridapulleyhq.com/gtp_products_frame.htm that is where I got mine from. They were a little longer than the stockers but work fine.
In the summer it is hard to tell because your fans turn on somewhere between 195-205. I have a 160 drilled and unless I have my hi-speed fan switch on it goes right up to 205 area.
EDIT: Also the stock guage isn't very accurate. Straight up and down is somewhere between 195-210. And it is slow to adjust.
With the stock 195 stat my stock guage was always just under noon (200) it dropped down to ~180 with the new stat. Its not drilled.
It seems to react relatively quick tho. At a long light it will creep to 200-210 and begin to drop after driving a few blocks. I have a digital temp controller and 3 thermocouple probes I am going to mount to take various readings. That should be very accurate when I get around to actually doing it. Its just been too hot out.
I have got to take control of the fans, that is really the way to go.
