indy heads

[andyf]

I've dyno tested the standard port EZ heads vs. the Eddy heads.  I ran those tests on my 432 stroker motor (383 with 440 crank).  The standard port EZ heads were a disappointment.  They didn't make any more power peak power than the Eddy heads and the motor made less torque at lower speeds (probably due to the large intake runner).  We pulled the EZ heads off and had them CNC ported.  After being ported to the MW size the motor picked up a ton of power but the torque peak moved up about a 1000 rpm.  So the moral of the story to me is that you need to decide if you're going MW size or not and then go from there.  The big port stuff makes big power but you'll lose some bottom end torque.

The high port Chapman Stage VI heads are probably the best compromise since the have a super high flow small port design.  But they cost a fortune so I've never built a motor with them.  I would have loved to test them on my 432 against the ported EZ heads but I never had the chance.

well heads aside - just thought i would throw in some info...      i am possibly getting the Victor 440 EFI intake this week (not available to the public yet) and i just purchased an MSD throttle body today...   should be a nice start to my EFI dream

You do realize that the Victor won't clear the stock hood

I'll deal with that when it gets here...      been looking for an excuse to get a fiberglass hood

Firefighter. Thanks for the fiberglass info. I was looking for a hood to put a scoop on. I will never cut up a stock hood. I even put them in my favorites.

No problemo Dep....Glasteck is number 1 followed by VFN....both are excellent but glasteck gets the nod by a hair. 

Both companies will install the scoop of your chosing for a small fee. The bolt on hoods are what you want, heavier duty with lotsa reiforcement.
