ive got a 4 blade fan off of a 1970 camaro is it the same kind that capital and some other race shops are selling? it looks like it doesnt have much pitch on it and when i used it, my engine ran hotter than usual....someone told me that the aftermarket 4 blade has more pitch to it and it supposed to be better than the 5 and 6 blade fans and ideas fellas?

they are not all the same..i've even seen them on a slant six dodge(less pitch),the one you need is off a diesel.

I have a 77' monte and the highest my temp gauge ever got to was 198, I bought a fan from Summit. They are called Summit OEM Flex Fans part # SUM-G4917 for a 17" fan, and SUM-G4917 for a 18" fan. It pulls alot of air thru the rad. You might want to check one out.
