hi i am new to this sight and have some problems with my new 350 4 bolt in my 64 chevelle/ elcamino. i put all new parts on and have heating problems. for example, it heats up to 200-207 on surface streets and then i get on the highway it will reach 215-217. it has 2 electric fans 16 inch, a pusher and puller. i have the new edelbrock permistar long water pump,new radiator(not alluminum) and all new hoses. 180 thermistat. now i am old school and i remember the 350 running alot cooler than that. some people tell me that these new motors run hot. can anyone help?
