My 318 dyno results
What's the story on working with these Edelbrock RPM heads?
Do the combustion characteristics change going from to warmed up more than cast iron heads?
When I hit the hiway with cold heads, I can always feel them come on line, when about two or three miles down the road, the car starts to surge ahead with no change in throttle setting. I often get about 2 to 3 more mph after the surge.
I painted my Eddies with three coats of Orange paint, in an effort to keep some heat in them.
This is also why I run them at a minimum 205*F.
Also why my WP is
underdriven.
Also why I run; an all-steel, hi-attack angle, 7 blade fan, on a hi-flo pump,with a T-clutch which appears to keep the maximum coolant temp to about 207*F................... no matter what.
So,after the warm-up period, the window of cooling system operation is always between 205 and 207ish. That makes it easy to tune with fresh cold air coming down thru the hole in the hood.
Is this different than iron? IDK I haven't run HO iron heads.
