This is why I give guys before and after flow numbers. If you go on Stan Weisses head flow website you may notice a pattern of high numbers. I know I have and ignore those posted

I use to flow my own stuff at work.. I'd just stay
around after work or do it at lunch time.. it was
in the head lab at Chrysler.. their numbers I could
go by since they werent trying to impress anyone..
they just got as good as they could with a certain
design and then it went on the dyno.. that is the one
thing that I miss after retiring... but thats all

PETE --- How much more power can you make with mcs over the originals ? I have the originals just wondering it is worth going to mcs. what is the most power you can make with b1 originals on a 540 ? thanks Ed

That's a tuff question and everything being the same (but why would you ) maybe 40 to 50 and that's maybe. Every engine we build is different and not to many what all they can get, some due but not many. Maybe give us a call and we can go over you combination .

A flow number is just a number and a higher one may or may not make the car actually go faster. We also don't race dynos and flow benches.

Several guys, some on this board even, spout some ridiculously high dyno numbers for their motors, but when the car runs, the numbers just aren't there.

I get calls every day about motor combos. Seems there are guys on every street corner with 434, inline valve head small Chevy's that make 900+ hp, according to them, or some dyno sheet they have in hand but I have been doing this stuff a LONG time and have YET to see one myself.

So when it comes to flowing your heads or dynoing your motor........find someone you trust to give you REAL numbers, be they good or bad and who is not interested in impressing the masses.

Local shop to me has a dyno he calls the "Humbler", because he is NOT an engine shop and has no affiliation to any. Just a dyno facility. He hurts LOTS of feelings...........LOL!!! But funny how the engines he pulls, the cars run where they should. What a novel idea.......LOL!!!
