Edelbrock Pro Port

It's .800 lift, 15:1 c/r, heads are 60cc.  I have a program that comes out 64cc, so I only had to mill them .020 to get to 60cc.  That saves fit-up headaches.  I think we took .015 off the manifold, and used .030 thickness gaskets.

Nice Job Blair!!!  Curious and surprised no one has asked, but what car is this beast going into?................Al

[hyper64]

1965 Falcon with a Marc Markow chassis

Nice looking heads and great power out of that build. Good job BP. How about some more info on the car, it should scoot pretty good!

BBM tunnelwedge and a pair of 930 cfm Holley carbs

Hi Jim, are the 930 centre squirters a custom carb? If so, who made them, if you don’t mind me asking?

[CaptCobrajet]

I supplied the custom carbs.  Booster and venturi work got the extra flow.  Also converted to screw-in bleeds, etc.  Carbs got the full treatment.

Blair...

Thanks for the carb info! As a one time user of 660's,I wondered how they were flowing that.

More dumb questions....Titanium valves? Tool steel retainers? (On the pictured heads)

That BSFC is freakin incredible....

Not an expert on BSFC, but I would imagine the 15:1 compression ratio has a lot to do with that.

Ok, you guys busted my cherry, I have never seen a set of FE heads like that before?  Blair what does a set of heads like that run

[e philpott]

Ok,   Blair what does a set of heads like that run

They run FAST  , lol

Blair what does a set of heads like that run

I'm thinking this is where he's gonna say, "call me".

[CaptCobrajet]

Yessir.  I don't want to throw numbers around on the forums.  That stuff is best on the phone or private email. Thanks.

Cobradriver......we used hollow stem steel valves from Ferrea.  More durable than titanium, and with a 6800 rpm peak, it won't see more than 7500 rpm.  Plenty of control there with 980 lbs open pressure.

I'm super curious about the plug wire boot contraptions on the bowl vents... Just when I thought I was pretty much a carb expert... I would not be the least bit shocked if that was an original idea from Mr. Patrick either... Still would love to know what in the world those are intended to aid... If I had to guess, has something to do with stabilizing pressure to bowls so the jets flow *more* consistently when air velocity picks up...? I can see that eliminating a few moving targets tuning wide if that's the case...  If willing to answer, but maybe not on the forum... You know where to find me!

Awesome work, so much admiration/appreciation for the kind of work shown in this thread.

When the air gets to moving at high velocity, it can suck fuel up through the vent tubes and into the air flow. That contraption stops that from happening and still allows it to vent. Notice the holes in the cross tube.
