hello guys still working project. lloyd has finished my intake. I havn't seen it yet but he said he moved port more to top and did some epoxy work in spacer to match. hope to be home soon for awhile. My little job in new mexico has turned into a big job. hoping to be finished in later august. Making some bank$$$$$ but no play time. photos soon and flow numbers.

Looks good.

It also sounds good that you are making $bank$ -- 'cuz there is always time to play later!  I understand that no bank = no play.

thats the only way they make them from edelbrock. mine has been modified extensively. Once I get home I will have some photos. of finish product for my application. They say you don't have to do anything but as you can see the missmatches it needs some work. Some of the turn downs to head need some work also. Been working away from home a lot and haven't got caught up on photos. will be almost 3months on this job and killin my engine time.

Very interesting.
Woody is doing me a 393 with a Air gap on top of TFS heads, I really did not consider the intake needing work.  :wonder:

I forgot how much stroke a 393ci engine has?

May I ask why a Air Gap and not a Super Vic intake?

393 is going in a 70 mach1. I want to just cruise. Car will never be raced or see the track. The air gap
seemed to be the best choice. Not sure the Vic would fit under the hood. I told Woody around 500HP max for my needs.

If looking at the air gap you can see lots of material that can be removed to achieve your needs. I'm only turning about 5500 max rpm. This is my head guys first 351 cleveland air gap and got to have some fun. new product out and still being learned. catch you guys later. will have some photos soon of my project. :ban

I recall a lot of the cleveland guys liking the torker or preferably the Offenhauser? port o sonic.  Torker comes in a 4bbl version.  Thinking of trying that one for my 70 Mach.
Ever consider that one?

will be home on the august 5, 6, 7, 8. Everything is done and will be getting assembled by end of month hopefully. My next situation is carb. Talk to pro system and they are thinking 950 annular setup. I was thinking around 800cfm annular for my application. Debating on quick fuel 850 cfm vacume secondary with annulars also. gonna have to be built by quick fuel.  5500lb to 6000lb truck manual tranny main rpm range is 2500 to 3500 rpm for highway running and pullin the mountains steep grades with trailor sometimes. Pro systems I really like and the fact they build their carbs per customer. really like this personal touch. catch you later. photos soon?

can't wait to get everything photographed myself. I've seen a few of these engines but not a lot of info on builds found. I will document just about everything possible. Put together many engines but never really took the time to document and always kinda new what to expect. this paticular situation I'm very curious to see the end result. My only problem is my job is killing my play time at this moment. If not familiar with Lloyd creek he's pretty much the creator or wet flow systems with Joe mondello. Once meeting Lloyd I know he's the brains behind this new tech back in the day. pretty sharp dude and a mad scientist kinda guy creating monsters that happen to be engines.

hope you can see the work Lloyd done. should be a little monster 400cj. the first cam I'm gonna try is a hyd roller .520 lift for this application. might be a little conservative but will get the job done. If I don't like will have scott at MPG heads cut me a new cam. been using scott for many yrs in englewood colo near denver area. We spoke on a few cams and this is the first one we are gonna try. Playing in high elevation can be tricky sometimes. 5000' and higher is my norm.

forgot to mention the work done by Lloyd looks excellent. Ask why so much was taken out of port and he said th keep the velocity correct with my application. everything flowed and velocity check and swirl. for my application this is all I need. The air gap intake was hogged out alot on the top to match up to 4v heads. air gap has lots of material to play with just for these application. from the looks glad I got to meet lloyd and let him do his thing mad scientist with the flow bench, head cutter.

hello candoo. air gap stuff. the center ports lower the turndowns into head need some work. Air wants to jump into head and you get a dead spot at the turndown into head. Also the steps in ports definetly need to be smoothed. Also if going to 4v heads you take a lot of material on the top of air gap  portsto match up to 4v heads. this actually helps this out and kinda straightens the port. Pushes the air to top of intake port and can see good  things happening. This is all bench racing but common sense tells me its a good thing from my past experience in porting world. Also the flow bench and velocity checks tells this also. Really like this air gap dual plane and has lots of potential for the tuner guys if you want to play. catch you later and drop a message if any other thoughts.

It will be interesting to hear how the intake performs, general census on them is too leave them alone and not to open them up to suit the big heads.  They certainly do perform quite well OOTB with just a minor clean-up.
Time will tell.....

is there any work done from the top/plenum side?


Title: Re: air gap intake
Post by: wyoming4x4 on August 12, 2011, 12:07:01 am
yes some work was done to work the turns into ports. Just bigger radius's and some casting flash. Flow all ports and just try and even out. The lower ports center the turndowns needed work. Air was jumping into heads and needed some work. this is the simple technical explanation for the center ports. With the big port heads you kinda need to work the air flow up to top of cylinder coming from air gap. my computor won't let down load photos for some reason.

the lower ports are where a lot of work was done. the turns on lower plenum below carb and the turns into head lots of work. trying to get everything even on flow. Lloyd was busy getting everything decent.


Title: Re: air gap intake
Post by: wyoming4x4 on November 28, 2011, 12:22:11 am
 forgot to mention the heads are flowing around 300cfm at .520 lift. but with intake on it flows 272  cfm. little restriction from the intake plenum worked a little. the upper ports flowed east but the lower ports needed the work to get even with other ports. lloyd did some nice work and the flow bench don't lie.
