hey El,Don't forget,this engine is a furnace.If the pump is too slow and the heat is generated too much,then at idle ,the water can't cool enough.This is evidenced by the fact that on a cooler day , no problem.You dig? Does it make sense now?Also don't forget that when looking in the expansion tank,there is very little flow at higher rpm's.I do think you're right that the airflow is also a factor so I'm gonna get a fan shroud so I can utilize all of the radiator surface instead of 65% .Viper fan huh,thats a thought.but remember that this is a show and sound car and a radical cammed engine.Do they make the viper fan in chrome?Are you saying that both the water pump and crank pulley are the same size?that means that it's a 1:1 ratio.If it works for u that is fantastic but for a furnace producing engine ,I think that,s the difference .NOW TO BULLETBROWN,you are absolutely right about March.This engine needs a faster flow due to basically the fact that it has been set up as a high rev engine though I dont run it that way so I guess I got what I bargained for,a mixed bag of problems to solve one at a time.Hey thanks for the imput guys.Ya made me think even more now.Love talking to everyone.Don't stop now.Everyone is a help.Give me more! Love ya all my friends.By the way,this is the blue and silvered striped ,chrom engined cobra at the Shell Valley display at carlisle this year
