went edel victor,finish heads,mockup

I was curious as to which numbers meant which numbers I'm assuming the second row is thw adapter use to flow at those numbers and the second line is the results in CFM, yes? Also what are the top numbers ?

Look like port dimensions to me

I am watching this one! Are those the standard 77929 Victors out of the box? Mine started out as the standard port but were ported to MW size..I am thinking I went overkill on this!!

the heads are 77929.
1st # lift,2nd is flow range,3rd is flow in that range and last is calculated flow.

Thanks! Now I know I screwed up...Should have just did the essentials and saved a buttload of money...

Those #s look higher on the intake and lower on the exhaust than I've seen for other OOB 77929 heads, so I'm not sure how comparable they are to the rest of the data I've seen for that model of head.

In the long run they are just #'s to start with and a big improvement over my iron heads and for me a very big move to make that I have waited to do for a long time so I am happy to say the least.

Clanton,

So you are Boosting the motor? Try to raise the mid to upper lifts, the intake needs volume more than raw CFM and great exhaust efficiency is also important; that's what makes the Indy-1 with it's big Intake port and excellent raised exhaust a real natural for blower apps. You want to improve the exhaust to intake bias % since getting air IN is not an issue with boost, and for the powerband you're looking at...you don't want or need a ton of RPM since your torque band is going to be EPIC and roots blower efficency drops (heat) and tends to act as a big brake on the crank past its designed flow rate. Good heads and a relatively slow blower ratio really works great....if you get the cam and timing right it's almost unbeatable and VERY RELIABLE.

I have the Chaoman stage VI's and the most impressive/important numbers are the mid lifts. Basically if you get your .400-.500 OOTB lift numbers to where your OOTB .500-.600 numbers are now and IMO you're all set. beyond that with the blower you just let the peak fall where they may beyond that. Cam selection will be critical, how big is the blower and what CID and static CR are you at. JE makes a nice blower/nitrous dish design. Run as long a rod as possible

Yes the engine has a roots blower/carbs.The casting is rough around the valves and will improve a bunch in the low/mid range cleaning the chamber up and throat.The test bore size will help/hurt flow also so maybe it was done with a larger bore tube.The engine is a 446 3.75 stroke,9.4cr with the heads haveing a choke of 3.14sq.in. with 6800 rpm,.630/112lsa cam so I am sure my port air speed will be fine.

Look at the advertised flow here.

and mine is not that far off.

here are some good cutaway pics of the ports and how much they can be opened.

I would like a picture of a cnc exh port if anyone has 1 PLEASE!
Thank you!
I have a cutaway pic in stock form.

Not sure if this we help you but this guy does some beautiful work.

Let me know if you want more pics.

My static CR at this time with the closed chamber head change is 9.28 and dynamic of about 7.7

Thanks I appreciate you taking the time to do so! Good luck with your engines.

Your gunna need your COMP licence too

I don't even know where the closest IHRA track is to me

I guess I have been bored so I have been using the wallace calcs.Port speed will be 256 FPS[corrected] and the max velocity for that port csa/3.14 is 542fps at 6800 rpm.The gained cfm over my as working engine will be 70cfm with a hp rating anywhere from 1.4/2.0 hp per cfm N/A.The tune may change as far as fuel,timing but we will see.

I want to thank Koffels place for performing awsome work on my heads giving me performance I had only dreamed of from a std port opening.

You going to post some numbers Mike?
Let's see the sheet

The #'s are very good and when they are done all the way I will post them.

Please give us before and after numbers from the same bench. Those are the ones that count.

^They are.

Thank you Scott Koffel for the great work!

The ootb # are on page 1!

There is a MW port in this head offered ootb.

Pretty good numbers! I will post my flow sheet when I get it. It will be interesting as we both started with the same 77929 heads. Radar Lechtenberg did mine and he also said he never saw a flow bench win a race yet!!

I am excited just to have finely got some aluminum heads.

I made it tough on Scott to make more cfm by limiting the port.The bowl,port,valve job needed done so I did what I could.The bigger change in those flow# is I did have 280int/180exh cfm and now the victor flow.

I called wiseco about my valve relief size in the piston because the Victors have 2.20 valves and the good news is the reliefs in the K373A3 pistons are 2.350 and .190 deep and I wont have to take the pistons out to do work for that.

I got the heads back and they look AWSOME!Thank you Scott for going over the details with me and tech info!

I can progress to a bunch of things from push rod checking to intake,header mock up so over time get some and grab a

Well my headers fit just as good as the iron heads,my valve to piston without the .090 head gasket is .450 and the center of the int valve[.110] is .130 to the valve relief edge,the pushrod needs more clearence on the head by .100 tested at max lift with a std rocker and measuring to the perch where it runs on the iron head and subtracting the added .400 offset on the hs rocker they make for the victor head.

here is the old headers bolted up.

The valve covers fit nice but are close to the rockers.
