when I started lobbying Edelbrock 3 years ago . I was asked by Vic why should we do these heads
First these heads are designed to be better in every way then a stock head out of the box . The heads as cast have 20% better air flow as cast and 40% better cooling . My selling point was to make this head about the same cost as a head from a GM dealership. With this 95% of all of the heads, will go to people doing head repair on stock farm and tow truck. with that said , the Material is there to CNC the ports to be huge
Cooling is very critical in a performance engine. The problem with melting heads in not the material ,but the lack of water in the correct places.
You can't just make the ports thicker and not address water flow.
I have for the last three years, spent many hours on the phone with the engineers at Edelbrock and lobbing the powers that be for these heads. Chris Franks at Frankenstein did the port design work . Notice the dog leg port is designed to be straight enough to CNC now.
The casting has the metal in the correct areas to double the height of the port and take flow numbers well over 250% more then stock.
This is just the beginning. There is a race casting and a Chevy BBC version for marine use as well coming over the next few years.
When I started this I was told that Edelbrock does not move fast , but moves right, this head is an incredible casting.
To the kiddos that just can't keep from bashing , I don't care. my car is making power and running great.
