Well, you hafta have higher CR with alum due to higher heat loss, so depending on where you're at, that aspect might be a wash vs a stock Mag. The higher turbulence due to CR should still give benefit, though, but I wonder if the Mag ports compensate for that better than Eddy???

I'm not sure we could automatically say the Eddy is superior to a Maggie simply because it's 8 years newer, though. I'd bet Mopar had lots more resources to develop/refine that head vs Eddy (heads are crucial to emissions compliance), plus the heads are both for vastly different purposes. Both are better than an OEM bigblock head, without doubt.

Either way, Eddy is beyond the scope of what Pale is looking for.



I dont know what the small block Edelbrocks look like, but the big block ones came out around the same time and they're still based off ov 50 year old dinosaur tech. The chambers are a complete afterthought and for that reason alone i'd never use them. The Edelbrock Magnum heads look pretty good though.

Its not always about flow, and so many people still insist that it is. If it was just about flow we'd all still be driving rectangle-port big blocks, 460's and 440-1 Indy 440's around and getting 7mpg.

And yeah... heh... i'm pretty far away from budgeting a pair ov aluminum heads into the mix...
