For the W5 lovers

@pittsburghracer Best numbers I have seen are 330/335 from a W5. VIA Ryan @ the defunct Shadydell shop.

Now I’m not knocking your numbers are calling them out or suggesting anything here. But your number seem high to me.
With that said, I’m not a porter as you know and I don’t have a flow bench ether. It’s just an observation against other numbers I have seen on similar work. Your before and after numbers are what counts here in my book since they show the gains and the curve. That being said…..

I don’t know how far the metal goes on a W5 nor the Edelbrock or knock off head to allow more air in & out. I have read from a source I can’t think of is that the chink knock off head has more metal in the areas needed to get more cfm.

A simple FWIW, anytime I had a head flow tested and spoke about it, the crowd of supposed know it all folks will always ask and then state the following;

Always the question asked below.

1: Who’s flow bench/who flowed the head on what machine?

Always the response to my answer:

2: His machine is happy and inaccurate/he doesn’t know what he’s doing/his machine isn’t correctly calibrated/it’s not a good machine it should have been *** machine for a real/true reading


And the bullshit continues on.

Please continue to do what your doing.
