looks just like: http://www.besracing.com/cylinder-head-and-intake-packages/cylinder-heads/gm/bbc/bes-edelbrock-big-victor-3-heads
Did Edelbrock modify the BBC version to fit a BBF?

Apparently builders have been waiting years for the GM version to be released.

Thanks Carl, those look good. Now if they will just make them available.

Yeah, like the AFR heads.
Wasn't long ago everyone was calling them vapor-ware too.

Why should you be suprised? Nobody worries about the track or ET or Scoreboard. It's all about the BLOW Bench. That is what's important

It be cool to see some more 700"+ BBF's running at more tracks..... Too damn many GM's in the world.

The 'blow bench' as Gary calls it is a good tool. The issue with flow bench is that many people become a slave to it.....keeps them from trying things. Just because one valve job flows 470 cfm and another flows 477cfm dry does mean that the 470 unit won't out perform the other one.
It's got to the point where people are saying 'flow doesn't matter'. If that's the case why are those crazy guys still designing those taller better flowing heads?

Agree on this.

Taller "can be good" no doubt about that.

I am aware of engines on dynos which had heads swapped out and the lesser flowing heads produced more overall power on the given package than the heads with the higher flow numbers. A lot of this is about combination.Lem Evans wrote:The 'blow bench'....Just because one valve job flows 470 cfm and another flows 477cfm dry does mean that the 470 unit won't out perform the other one....

Very true, track performance can be affected as well. I've seen the same with carb's. Great dyno performers but sometimes out performed at the track with with a lesser valued carb. Correlation and building a data base is time consuming and costly.

Is that where these heads will shine or will the fit in other applications like the 611 Thor Gen 2 build?

That's usually because the flow curve is 'jacked up'. The newer carbs with 5 stage emulsion legs, removable restrictions and a guy that knows how to adjust them resolves that issue.

Plus, a carb on a dyno isn't moving!! That carb on a race car getting air rammed into it at 100+ mph changes the settings a bit!!
A little bit of tunin & tweakin gets the carb dialed into race condition.

Unfortunate, but true. Happy Dyno, Happy carb, skilled jack up tuner.

I will give up 20 cfm at .900 lift for 20+ cfm gain at .400 .500 .600 &.700.
Its about the average air moved in the same lift curve. Filling the cylinder the most in the amount of time you have to do it. And how it enters the cylinder.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This is true^^^
There are guys that'll fuck up the short side to get a big number @ .800"-1.00" and take the 'guts' right out of the engine.
