Hello: One of my cars is a 76 Lambo Espada with a Chevy driveline-nonstock. I've had a running hot problem ever since I've had the car-five years. Recored the radiator,put in a Stewart high f low water pump, special thermostat etc. Some of you Stude guys who live in Fl. may have heard of Cooled by Ice- a custom radiator shop iin Sarasota Fl. He specializes in overheating problems,mosty high performance hotrods.
I had the car towed down there, and he told me the radiator was too thick, the electric fans not enough cfms,and the plumbing was not right, and he would do a dye test to check for leaks.. A week later he called to tell me the car was finished, held 170 degrees running at idlle for an hour, and the 170 held running dow the road. He said he built a new aluminum radiator,flushed the block,put on bigger fans,redid the plumbing,and wired in a relay I haven't p,icked the car up yet so I don't know if the overflow system was changed. I thought the bill would be around $1000-nope wrong- $1581 a little sticker shock.
Regards,Sheldon
