My new head

[63comet]

Well, I went and picked up my head at the speed shop today and was all excited about posting pic's here. When I opened the site and saw the pic's of the new Argentine head, I almost decided to not post any pic's. Almost, Mine will not cost anywhere near that one. Anyway it's a 78 head with 144 intake valves on the exhaust size (1.44), 1.75 on the intake with 3 angle valve job, and 302 exhaust springs on both. The head was trued up and had him install a pair of Weber plates so I can run 2 weber DGV-5 32/36 carbs. What do you guys think I ought to do with the center hole, (split it with divider, or just cap it off), or throw an adapter on it and run 3 deuces? I think 3 would be too much for the log, but 2 should be fine as long as they are progressive. Her are the pic's;

I'd make a divider that blocked about 80% of the flow, and braze it to a cap.

can we get pics of it without the carbs, from the top down?
i'd like a look at that

 

[addo]

Forgot to add - I like the welding. It's clearly been well heated beforehand.

 

[63comet]

Addo, Actually, no welding at all he machined the log flat on both spaces and bolted the plates down with a couple of bolts in each, he then filled small openings with an epoxy that he has that he put my single adapter on my other head, I am not sure what the epoxy is, but it is super hard and has held up on the other head for 3 years now,

you can machine it and drill and tap it also. I'll try to get pics tomorrow with the carbs off, I still need to clean up the holes a little bit and put freeze plugs in and fabricate some linkage.

That epoxy sounds like a good permanant fix for leaky Offy tri-powers. Can you find out what it is?

 

[Patrick66]

that looks great. ive thought about it, but ive never seen 2 2v on a log. good luck with the linkage.

This is really cool. It's one of those things I've been thinking about for a while.

You seem to have the two carbs in the best locations to get the best flow from them. I'd have done three 1v's but hey, that's just me! I'm having my head worked as soon as the valves arrive. I'm using the same 1.75's as you have and 1.5's

Take a plate as already mentioned and cover the center hole, then glue a statue of "Rat Fink" on it (good ol' RF! Yez Yez). Just kidding!

I love how more and more people are pushing the envelope with these things. Awesome Job.

 

[Ronbo]

Thats great! We talked about this over on the Clifford forum back in 99. Glad to see someone finally did it! Those DGS carbs are pretty awesome too eh? Where did you get the throttle lever piece from? I was looking for something like that but ended up making my own. That one looks better.

That's very cool. It looks like your carburetors would be set lower than if you had used a an adapter.

 

[Soldmy66]

Please keep us updated on this. I, for one, think this is a great approach. I'd really like to hear your thoughts on this once you have it running.

Very, very cool.

 

[sp_alloy_head]

could it be JB Weld or cotronics epoxy(www.cotronics.com)? Anyhow, I like the idea.

Hi guys, Called the shop today to see what the epoxy is He uses, He was not available, headed to North Carolina for the week-end, I added some pics of the plates with the carbs off, you can see that they are opened up to the holes, but I will just tweak them a little. He lined them up with where he thought would be the best flow for the half of the log. He loves working on old school stuff, he said some guy came in his shop when he was doing this and the guy said what to h-ll are you doing this for, doesn't the guy (meaning me)know gas is getting expensive, The shop owner told him, you don't understand, I would rather work on this type of project and charge the guy about half, than work on your Honda. Also the carbs are definetely low enough not to cause problems. My biggest concern is going to be with the linkage, but I don't foresee any problems. This project may not get done for awhile, I have a 200 with flattop pistons and a 264/274 cam ready to accept it and I won't be changing my 250 out until I have everything set and ready to go.

Looks, Great!

I would make a plate with a divider that doesn’t actually block the flow from one side to the other. I would think that you would want some flow to equalize the pressure between the two sides.

You are going to have to invest in a couple of Sync meters once you get this going. Check into the VW sites for the meters and some processes that will help with the tuning.

Have fun, Ric.

Thanks for the support guys, was wondering why you feel that it needs to be split , but not totally, why not just cap off? I am questioning only because I really don't know. When installing 3X1's no splitting right, Thanks for any help.

 

[60s Refugee]

Right, 'cuz with a tri power there is a carb sitting there (instead of a statue of Rat Fink)

Kind of like a dual plane manifold. Suppose to provide more torque.

here's my take on splitting
if you split ang go with a dual out header, you can have two o2 sensors.
(or just two bungs and move the one o2 sensor)

it's a more accurate way of tuning each carb 8)
