Great day for porting

I don't know if he was happy or not , thankfully this was a forced induction deal that likely made the heads perform, flow results be damned. J.Rob

but then again anything with a power adder should run. You took half of the effort out of it. I’ve had well over 5000.00 worth of nitrous stuff sitting here for years and have almost zero interest in using it. The class I bought it for exploded in cost to run and to run them isn’t a one man program to run effectively.
 
I finally have electric and water back after going 43 hours without it. To hot now but back to the shop in the morning. Man this storm hit our area hard. One homeowner was hurt and beautiful riverfront property damaged from they think a generator explosion. Not sure what happened but I can take a few guesses.
 
I’m pretty sure I know who the owner is...... and where the heads were done.
And, if I’m right about that....... then I’m pretty sure I know why he had you flow one.

Yup Ron's (the guy you did the 572 for) buddy, what a PITA this new job is turning out to be. <<See aluminum main cap thread. J.Rob

Glad the Power is Back on! Was wondering...

It’s on but wow. My in furnace motor and blower cage for my air conditioner went early week and it’s 85 degrees in my house at 8pm tonight. Hit the shop for awhile but with no air conditioning in it the thought of climbing into my coveralls I wear while porting wasn’t going to happen today. I’m to cheap an stubborn to pay someone to fix my air conditioner so it’s on my to-do list.

Dammit Man!

I can top that!
We had house guests last year over the fourth of July weekend. The air conditioning literally blew up, and caught fire. It was 115° here at the time.
Our guests cut short their visit, and it took us a couple weeks to get a new a/c. 90+ degrees in the house at midnight.
 
Yeah that's the BIG difference in what I observe-the starting point. An OOTB Eddy RPM--Goes 257-263 cfm on my bench untouched--Heck a OOTB Victor does 278-285 as a starting point. I've got some SideWinders here ported by a BIG name guru here that I was asked to flow that peak at a whopping 287cfm--sold as flowing 318+cfm! The customer was pissed as he thought they were stock--I assured the customer that OOTB they would be in the 257-263 cfm range--He felt a little better but not much. J.Rob

Is someone selling small block heads that they claim are flowing 318 CFM? Did they move the push rods over?

No my post had BBM heads in mind, however don't get me started on the "BigMouth's" which are a small block Eddy and DO have a relocated pushrod and DO claim to flow 320+cfm but the murdered S.S. only allows them to flow 284 cfm in reality as observed on my bench. J.Rob

I got exactly 318 out of my old open chamber head with a 2.08 valve and have gone so far a best of 6.06 at almost 112mph@2880 pounds. The heads are tubed and I had to take everything available to hit that number. (Stock located pushrod). They are approximately 185cc runner and the short turn is not taped like some insist on doing. Lots of time and labor to get there.

@67autocross

might be coincidence, but the Promaxx BBM heads are known to be the same castings as the Sidewinders, the CNC ported heads are advertised as flowing 318cfm at .600"

Man that sucks. Our central air has been gone for over ten years. We make do with a 10K BTU window unit. It keeps the majority of the house cool on all but the hottest days. I'm just praying it lasts out this season, as the control panel has malfunctioned and I cannot adjust the temperature on it. I'm kinda glad it's stuck on 70 degrees. LOL If it makes it through the season, I'll catch a new one on sale at the end of the year and donate this one to the local Christian thrift store. I wish you the best in getting yours fixed.

i believe that about the big mouth heads have a set the never performed like the advertized numbers claimed , they were tested on a happy flow bench no doubt can you post the real numbers ?
