OK I have took the old radiator out after tank cracked slightly while car was sitting in idol. I also took the water pump off an discovered it was completely clogged up at the top of the pump with looked to be like sand or sugar.This car is a barn find that i have been slowly working on since last summer. I have also took the lower crank pulley off because it was bent where im guessing previous owner unstuck the motor. My question is should i go with a new aluminum radiator or fix the old one.My car does have ac an the original radiator came with a trans cooler. If i go with a new aluminum do i get one with the trans cooler or get one separately? Oh yea whats the best water pump for the price an who has that 3 groove crank pulley for my 66 nailhead 401? Thanks
