What do you guys think?

Kind of sucks that they put the injector bung way into the top of the port where all the flow is.

edit: This is a Holley 9901-101-1 intake, AKA 'Commander 950 MPFI'.

POSSIBLY if you glue it down. Either use Rightstuff or 3M weatherstrip adhesive...if this is your boosted build, then you may want to use some epoxy and build up some material around that top of the base.

Else leave it 1205 and just have it step down into the 1206 head. Boost will make the power.

 

Yeah thats a good point, leave it at 1205. (it's actually 1204, freaking holley!) But I can port it out to 1205. I just hope the afr 210 has enough flange to seal.

If not, I guess I can have it welded and milled ?

-- Joe

 

To answer your question, no. If as Orr says you are planning on boosting the motor than carve it out to a 1205 gasket. If not and you want a 1206 than welding is the answer.

 

Lots O boost through new AFR 210 heads (310cfm!). I could just carve it out to a 1205, as long as it seams to the big afr ports, which are a little smaller than 1206 if I recall.

How much do you think it would be to have it welded and milled flat?

-- Joe

 

"How much do you think it would be to have it welded and milled flat?"

I really don't know. The guys I use are both retired but have their own shops so to speak on their property. There rates a lower than normal.

About opening the mouth of the intake to a 1206 gasket or slightly less for the AFR heads. If you are not going to open the rest of the intake and runners to the cross sectional area of the manifold opening to the head it will not do much good. You will still have the choke point further up the intake tract. I can tell you that requires a lot of work if you have been following my threads.

 

Yeah I never had a intake welded...for my heads that were too thin on the port floor, I went with a 1/8" piece of aluminum plate and epoxied/screwed it to the bottom of the head to build up area

For you, it may be possible to use epoxy like JB weld and quiksteel putty..it holds up ok. Real good stuff is A-788 splash zone. Then take a dremel and shape it.

Welding is the right way and remachine it but that could cost abit more than its worth. If you have the flange area on the head to seal, I'd leave the intake 1205. Boost wont care

 

So. Apparently the Professional Products / Procomp x2038 intake has the same injector spacing, and fuel rail mounts as my holley. So in theory, for around $180 shipped I could have chinese intake. One seller says it can be ported to a 1206 port, and the injector does look like a better location than the holley.

Any of you guys use one?

The only issue, is the manifold is 6" tall, and I think with a carb had it won't clear the stock hood..

today ya get what ya pay for anymore. i like the price on some of the intakes, and i would have loved to spend less then $200 on a nice singl plane EFI intake.
but i gave up over $500 for mine. and this is what a felpro 1206 looks like on it.

match to the AFR 220 heads right out of the box. doing nothing to them.
can you say Smmmmoooth flow!

accle proram/motown/world prdct

 

I picked up the chinese intake. It has better port entry than the expensive holley I had, fits a 1206 with tons of room to spair, and had a polished finish for $180 shipped.

I sold the Holley intake on ebay for $240.

-- Joe

 

after the big names did all the testing i went with the one they picked out with the best flow Numbers. holley was not on the list ether.

i always liked the look of the polished intakes. maby after everything is running. ill send it all off to get a polish and a chrome plate.
Hate to have to keep polishing it every few carshows

 

Yeah, I've always liked the holley for fitment, but when I actually sat down and measured the port (pics in first post) holy crap. It's not great. It's basically the same as the HSR, which accounts for the poor flow of the HSR I guess.

The chinese intake should flow more than enough for my AFR-210s, and the procharger feeding the whole package. If these were not available I'd probably have bought a pro-ram.

-- Joe

 

I bought a HSR right after they came out and port matched mine to a set of heavily ported brodix track1s. I had to weld and add material to the hsr and then have it re-machined since the welding process warped it slightly. The hsr was then ported and we flowed it through the entire intake assembly bolted together and it flowed a little over 300cfm. It cost $50.00 to re-machine the hsr back flat and I did the port work on the hsr myself. The heads were professionally done by Greg Vandeventer in Yale Oklahoma. He also finished the hsr and did the flow work. He does work on LT5 zr-1 corvettes from 90-95 and he did my 90 zr1 years ago. There is no one better. I took the car to Ed Wright and it made over 400 rwh and over 500 rwt. This with a bad fuel pump and bad regulator. Ed suggested a new pump and regulator and larger cam. The hsr can make big power if you grind on it some. After we were through I use a 1206 gasket and have to trim it since the ports are slightly larger.

 

the pro Ram can also take a 1207 gasket has well.If ya have to use one, that thing has got some meat on it. and the flow rate is 300 cfm out of the box, bolt on.

ya end up matching the gasket to the ports,

has for the holly s ram..never have liked the looks.

and spending $2500 on a custom made sheet intake is what i would like to do, who knows maby the nexed old school chevy eng, a 572 with a hand made intake will be the nexed one.. (after back halfn) the car

 

Well if custom is what you want then Hogan or Wilson will certainly fix you up for about $1600.00 and up depending on how extravagant you get. I want someone to make me an intake for a set of -12 brodix heads like kinser and those guys use that flow well over 400 cfm. Those are expensive but that is where you get what you pay for. Raised runner, over 300 cc, made to flow lots of air without any compromise, 12 to 1 minumum compression. Ed Wright shared some info when I was at his shop getting dynoed and that guy is sharp. He is not afraid to spend money either, or take yours. He does excellant work though and I highly reccomend him. His philosophy is "think small block and you will run like a small block. Think big block and you will run like a big block. Think farther than anyone else and you will go farther than anyone else".

 

That's good advice. Big inch small blocks can take big block airflow. Feed them! Lol. On side note my victor Efi can be ported to 1207 as well. I heard one guy in the know claim this victor e intake sucks compared to other single planes but I know of atleast one car running it with great success. Actually 2, an lt1 made the switch on a boosted setup and picked up big power over the stock but mild ported lt1 intake

 

yes i have been looking at Hogans web site. and if i spend $2000+ on a intake, it's going on a big bigblock.

this small block im working on now i went with open chambr heads to get it down to 11.5 to1 from the 12.5+

even at 427 cid, this will be the last small block for me.
i have so much room under my hood now.

a 572 would drop right in.
