Good question Mike! The 110 is my first ever flow bench from about 40 years ago. That said it will flow a big block head short of a Pro Stock and can still do it as long as you are able to read the inches of depression. I go very low and they give you a conversion chart using for ex. 5" and convert to 28" which is the standard most use to comparing numbers. However, flow benches are like dyno's and can give somewhat different numbers so one must be aware of what theirs is actually reading accurately. Using a 110 for ex. will give me a flow numbers of 400 @ 28, from my experience when I bring the same heads to somebody with an SF600 or bigger the numbers shows actually 10cfm more! Seen it happens with others but let me tell you this as a parting comment. Dynos flowbenches are nothing but tools and even if you have a very expensive snap on tool box as impressive as it is, a good technician with a basic craftsman might just do a much better job because they are more experienced and have the proper background. Obtw, I reflow my heads on a "better" flow bench just to cross check and the numbers looks better from what I get out of my tiny one. Here I would rather have a lesser number than a bloated one that will skew my belief that I have a better cylinder flow numbers.

Thank you for an awesome response, most of my questions on other channels are answered with a single sentence, even when I ask a couple questions. I would like to buy a flow bench and randomly see the 110 units, which are more in my budget. I have also considered the unit that runs with shop vacs and a laptop. Thank you again and I enjoy your content, my son has a 04 GT that I know he would like to hop up, but he needs a job first. I have a 69 GTO w a Ram Air 3 that I’m working on and want a bit more flow from the heads w/ out going Aluminum. Thanks again and keep up the great content.

@@mikemcnamara2943 thanks again and if you make a home made flowbench accuracy can be a secondary importance. What you must note is that it is repeatable and any changes you do can be traced back to your flowbench for posted flow increases! This way you can see an "actual" flow improvement absent of an actual number posted. Everytime that horizontal meter shows a decrease you are improving flow and when that tapers off take to someone with a good bench and have it flowed so you have your actual cfm rating. Good luck Mike!

@@benalamedaracing2765 thank you!!

It seems like it but it is actually the second looks like the rest of them. #1 is in the shade and I focused on the 2nd port but basically the same hue. I should have laid it down facing the sun...

We do not want the port to be too big as it already is. The floor I always prefer a step and functions better by the way.

Thank you Mark and we are all here to learn from each other.

thanks buddy! Where you staying now? Out of Commiefornia I hope.

I felt he milled the maximum out of it with some semblance of quench by doing these. It can be done if you have the heads profiled and make a quench style piston dome on it and should do very well.

He is teaching a lot of us the history behind this magnificent engine and how it basically change the mindset of many on approaching their cylinder head choices.

We ran a 357 inch iron headed Cleveland in brackets for years. My chevy buddies think its a 408 lo. Its not.

@@stevecleveland357 that is the sad part with running Fords! lol When you run a Windsor there is no respect because Clevelands are so few and seldom seen! The gap is so wide that few people actually raced or competed against Clevelands.

What heads are you thinking about doing this?

@@benalamedaracing2765 I'm not sure, however a 2.19 intake valve on a 302 well it sounds like more than a block can handle. I would like to try a Cleveland Head on a408 or something like that. BTW, is the GT 40 Head even close to an Australian Cleveland Head?

@@rogerstill719 Gt40's will not compare at all and just use the Aussie heads. 351 non stroke would work with that head and if you go 408 make sure the ports are worked on for volume and flow increases.

Yes sir it is best if you have a rare C head or engine and just preserve them specially if they are a Boss or CJ. I remember talking with an "expert" on BBC's and he told me he knows everything about them. When I asked him did he know there are 2 engines in that block because 4 ports are doing the other 4 ports are not! And he gave me a blank stare and the so called expert did not even know his ports are not doing all the same thing like the combustion chambers are even worse! lol

@@benalamedaracing2765 Yeah. I think we can agree to get power all the cylinders need to work together. To tune the BBC you would need long trumpets on the short ports, and short trumpets for the long ports, yeah? Now grind a cam with two different profiles, less overlap for the long ports with the hemi like flow across the valves, and more overlap for the shortys with their lower overlap flow. Headache's. Just put the BBC in a truck, and put an aluminum head on the Fords for racing.

Open or close chamber for that 400 build?

@@benalamedaracing2765 open the current open 2v head have great power and i run 87 gas its in a 1981 short box with 2 75 rear gears
