I have a Hayden heavy duty thermal fan clutch sitting on the shelf you can try, give me the word and I will mail it. It pulls too much air for 6500rpm engine. I went back to a standard duty.

I wouldnt think the single row radiator is the issue unless it is just of poor quality as I have ran around for years with the stock 2 row SB rad in front of a 10:1 468 with no problems what so ever.

What is your timing curve? vacuum advance?
