Every mm of the ports from carb to headers will be hand worked in nascar or indy engine. And in most fast race cars of all types.

I have done a lot of four valve and five valve heads in my day and i used to charge a crap load of money for it. To guys that had flow benches trust me 5% difference in ports would result in never hearing from that customer again cause his heads would perform less than stock heads.

Stock chevy and ford castings are so bad its easy to pick up a few hp. But i dont recommend you do it at home first time on your only working set of heads. Either do it rigth with a stack of practise heads and get the proper tools or get better heads. Knocking down ford exhuast bumps or other large casting marks is easy but most people go way to far and loose sight of the job before the first port is complete.

Its not hard to do a good port job at home but it does take some practise. And lots more practise and sometimes even a really bad port job will make some good power.
Those numbers where later published in Engine Builder Mag.So I am confident they are reliable.

and might be why they almost went bye bye in the 90's


I can tell you this, not one port on any nascar 357 is the same and there is a purpose for it..
a cnc'd head with mirrored ports will slow the cars.. with a single plane intake.. let them run 8 throttle bodys over each cyl. then mirrored would win out.. not untill

Yeah but NASCAR has always had odd ball combo's.I bought at the Indy Drag Racers auction a NASCAR 4.3 and had contact with them until it was done.It is the reason why the teams start with rough forgings or a blank slate. We had been going to that auction for yrs and there was time when Indy cylinder heads ran the event.We got to know them and saw some of their exotic workmanship.Just works of art.

No, 1Gary, that was not directed at you. And no, bygddy, it wasn't directed at you, even though for some reason you felt you had to reply after I said that the things you enjoyed with your boy while porting the heads justified it, but if you want' to continue to make a pissing match about it, by all means have at it.

It was directed to F-Bird88. I'd like to see the qualifications that he feels entitles him to talk down to people and say that his builds are the gospel. From what I've seen, he's no more qualified than anybody else. He just posts the most and the "loudest".

No, the difference between you and I is I'm smart enough not to waste my time trying to turn boat anchors into gold.

Yeah, just as I thought. No qualifications or certs to back up what you say? Did you even graduate from high school or have you spent your entire life on here accumulating 7300 posts on here acting like you invented the internal combustion engine? I hear there's an ignore list. You're on it for sure and I hope others put you on theirs. You just give plain old bad advice with an attitude.

Kid, you are clearly ignorant, F-BIRD'88 is a wealth of knowledge here.
You should take some time and refer back to some of his numerous posts and you will realise that his opinions are matter of fact and that advice that he generously offers to people here is good advice that actually facking works!
He has helped me and others tremendously.
This thread has gotten way of track and I hope the OP has gotten the information that he sought and some giggles along the way!

I can say the same about FBird and Vinny and even though Tech and I have never exchanged PM's, I sure value his knowledge.

You are very right on FBird and the point of this thread. I have definately got my answer and know what head i'm going with and very thankful for all the help. I didn't get any giggles from a few of the posts on here, got somewhat offended but I try to keep that to myself. I dont like drama and I really dont like young fellers that disrespect others.

Yeah, giggles is prolly the wrong word to use. It just amuses me how these threads sometimes go of on tangents.
I glad you got the info that you were looking for and wish you the best with your build.

You've been a member here for what...7 days and throw this attitude toward long term knowledgeable members? It won't be tolerated, that's strike one and two.
