you have to understand the box before you can/should think outside of it

 

Ive got pages of numbers I posted em on a local forum and got all sorts of **** from the ford people even thier 4v cobra heads dont stand up to a 2v ls6 head thats why ford puts blowers on everything they want to make power

 

well damit man, post that stuff up!

I have some stock 6.0L flow data I can post as well

 

That's my problem. I just can't stop thinking of box..

 

lol

 

ha...you too...3 MORE DAYS for my install!!!!

 

Keep me posted bro! I have another week or 2 before my install but my blower is sitting right her next to me. Taunting..

I have another box on the way over right now so forgive me if I can't talk technical right now.

I dont want to post ***** fl8's thread although it is tempting mmmmuuuhhahahahah

 

the 4v head seems to flow slightly less than the data I have for a 6.0L head with a 3.9 bore, but they are pretty close. the ford 2v head gets blown away though.

 

I think comparisons are slightly biased with chevy having larger bore size but the thing that gets me is with ford cobra 4v vs chevy ls6 2v your gonna have almost double the opening to let air in and out so the numbers should be far superior to the chevy 2v and they arent.
