General formula for potential power with a good combo is .257 x no. of cyl x flow at 28", so 305 cfm at 28", equates to a potential of around 628HP, just a ballpark, not a guarantee.

Well, itīs difficult to show any pictures of these without giving away the tricky stuff
I must say that I changed the shape of the intake runner quite radically, I did A LOT of grinding, and I had to use some epoxy to get the shape I wanted.

I don't think you will find to many people interested in reshaping eddy heads around here. there is no reason to go through that. to many better choices of heads.

I have a set of MCH cnc that flow 299cfm.
I'm sure the 'ball park' is the same.
Too many cars, too many parts, too little coin, too little space to work in, too little time left to make it all happen!
Update: down to one ride, still too many parts, a little more jingle in the pocket, gaining space, and it's going to happen this year!

Its simple, when I look for REAL world numbers I refer to Ryans site as his motors are proven over and over again so Id rather go by his real world numbers vs the secret sauce mumbo jumbo....to get to the same point. Ok cool, you got a set of heads that you say flow #300, welcome to the world of eddie heads. My neighbors flow 325, hes so tight lipped he wont even show a flow sheet as its got secret stuff as well, so I think I know where your coming from. On a different note, whats up?...not every set of eddies flowing 300 are packed with epoxy are they

with a 2.080 valve a little more than 300 cfm is a good normal number...
ive done magnum heads that are for super stock, 180 cc int runner, 2.020 valve,,, flow 285-290,, on a .060 over 360, 12/1, fuel injected make 685hp,, guy just set the record in ss/ia this past weekend,, in a 3200lb car or so went 9.62 at about 85% throttle,, ran high 9.40's at 3300lbs at 100% throttle

I'm sorry, it's been a while since I looked at the flow sheet. It's only 295 cfm. I still think it's in the ball park.
It doesn't matter to me. I have no intention of ever using the heads to their limit. I just wanted a good, proven performer for a cylinder head.

I sure know that it wouldnīt be good business to do heads like these for customers, itīs just too much work. No people just dont like ugly, Ive a friend whos are around 300, a couple pr tubes have tubes from going to far, some epoxy, ect...the heads are plain ugly, looking at them id run, seeing the car run id want to buy them. Dont be shy, post the pics we can all learn new things, my eddies are a consertive 285 with no epoxy or tubes, with square ports. Ive seen the tops rounded a bit above the square port line and there is about an inch on the bottom thats thick that could be port matched to the intake, I myself am comfortable doing a lil radius on the top of the port but dont have the skills to know what working over the bottoms might help or hurt.

mopster, nice work I am curious as to what the Indybrock port looks like. mopsters ports look like alot of work when you can just use offset rockers and lose the pushrod pinch but i have never seen a picture of the port and would like to if someone could share

the epoxy in front of the guide will create an "anti" swirl to the natural pattern of swirl natural to the valve placement/position... ls motors have that cast in,,, you can get turbulant airflow, or air disconnecting from the short turn and the vane,, or a particular type of valve job will help the air stay connected as valve lift goes up. everyone has seen air get turbulent or a head loose airflow as lift increases,, what he did with the epoxy will help that not to happen,, and for the head to continue to gain as lift increased
putting more short side on the head with epoxy is not a bad idea..

Looks like you did a lot of work developing what you wanted.I,for one,can appreciate the need/want to do things yourself. Please,keep us posted on the rest of the build! Keith

Nice work and I have no doubt your numbers are good judging from the amont of work I see in the shots. Also you have your base numbers for comparison which always make it easier to compare flow numbers to other benches. What has always been interesting to me is hardly anyone talks about wet flow and that if you consider a (for example) 12:1 A/F ratio at 300cfm, 7.6 or so percent (or 23 cfm of that 300) is displaced by the Liquid Fuel in suspension and fuel doesn't always act or swirl around in the port exactly the same way that air can or does. Also everyone understands say 300 CFM for port comparison but how many think about that intake valve being shut for around 2/3'rds of that minute? Even the more we know, we still learn more from "cause and effect." I've seen similar epoxy mods that picks up the airflow big on the flow bench but don't always correlate to a proportional increase in power. Also a port that doesn't work well with a carb may work extremely well with port injection (related to that very reason). Ryan said something very insightful (I'm paraphrasing) that he doesn't neccessarily concentrate on the flow on the bench so much if you know from experience where to port to pick up the power...in the end that's really the bottom line becuase nobody races flowbenches Take your intake duration at .050 and divide that by 720, take that fraction and multiply it by 60, that's how many seconds per minute your intake valve is actually open....and Unless I missed something that is constant regardless of RPM i use this to compare 2 cams @ .050 and .0200 becuase it gives you a 'real world" relative percentage comparison from one to the other.

Thanks alot for the pics. I'm doing a pair right now and I'll post pics of mine this weekend...they are right at 302cfm at .650. It's just fun to share...that's what this site was all about a few years ago... Brian

Nice job, are intake port and bowl in the Edelbrock Magnum head similar at all to the Mopar Magnum RT iron head?

Yep, Jesel stepped up and helped us with the drive. It fits R3 blocks, but we fanangled it to work on a stock block with Meziere helping us with the water outlets so we could swap cams, and make adjustments easier and quicker.
Just ran out of time to make any more HP but I believe there is at least 5-10 more in it with porting the adapter and lash change but no time left...was a looooooong 2 days! Brian

Well...it's going in a mag, so I'll be vague. We tried TTI 1 7/8 x 3" and 3.5" collectors, spacers, moved the cam around, lash, 3 carbs, timing. Father time was kickin' our but on this build and just ran out of time to try a different cam combo. Cam was in the 260's @ .050 and lift was mid 600's. OOTB 1000HP did very well against everything the PC 1000HP and PC dominator but the dommy was KING from 4000rpm to redline!

Oh man, everyone on the interweb knows a stock block won't take more than 600 horsepower.
Nice build and nice numbers. Hell some people were telling me I wouldn't make 650, and I have W5's and a tunnel ram. We'll soon find out though. Hopefully.

Looks like a nice build! Will this go on a dyno to be tuned,or straight to the car? I think it will perform pretty well once you get it all dialed in. Keith

The reason I ask is,I was wondering what you used for an installed centerline? I tested an older version of the MP 4120657 camshaft in my 421. I played around with the camshaft timing to see what it would do. This was an older version,312-106 that has a .404 lobe lift instead of the current design. I know a lot of people say to advance these camshafts a lot more than the MP recommendation, but with mine,it lost quite a bit of power past 104 installed. Every engine will be different,but I just thought I would pass it on. Keith
Any info on the current design? I just installed the current .590 to try out and installed it on a 102. Will keep ya posted on what it likes.

I've genereally found if the port cross section is relatively small compared the the cylinder swept volume (as is usually the case with a lot of wedge strokers), putting the cam in later helps the top end power, also an under-ported motor (if it has any decent compression) generally has an abundance of torque to begin with.
Advancing the cam generally works well when you've got plenty of port, adequate cam and compression but you're wanting to "use it all up" within a certain RPM limit.
