still having a few problems with engine getting hot in city at stop lights.. I finally got the fan inside the shroud which has helped more. but I am looking for a better shroud that covers better. mine goes all the way around but has lots of open spots. on the sides. where it butts up against radiator. and around top rad. hose. I have seen bigger better shrouds on some 70 formula 400's but did'nt get a chance to talk to owner. I have 68 with new 3 core rad. with new clutch fan.. and new plates in pump. was also told that if you powder coat plates in pump that help alot..
