Does anybody know of any?
Specifically looking for ratings for explorer upper/lowers.

 

Nothing? Damn...

 

there is a chart floating around somewhere, I know ive seen it, it was in some old issue of mm&ff that was scanned

 

Hmm, thanks for the tip, I'll do a search.

 

Here's the link for anyone wanting to see it...
Super Intake Shootout - Muscle Mustangs and Fast Fords

 

you have to ask your self though is that free flowing or is that mounted to a head?

the best info is the shit mounted to the head..theres a reason why porters like having your intake when they port your heads or do both..

with out each one bolted to the other you dont get real world numbers..you get free flowing numbers..

 

That is only a dyno test comparison, and the GT40 is putting out alot more torque then the others.

 

i was just saying how shit should be dont when flowing a intake or a head.

as for the shit and more tq..just because they did it dont mean that played with timing to get the best numbers out of every combo.

 

those were free flowing, it be a really huge chart if they were based on heads attached since there are 20+ heads for SBFs. There is if you search around, a few articles that mm&ff did called the ultimate head shootout, it covered several issues

 

Did you even bother to look at the link?
The only tests they run are dyno comparisons, on the same kind of heads.
