Stale Air boxes on 1600 twin port?

[greek_tony]

Searched a bit, but can't really find anything.

I'm fitting an oldspeed looking 1600 twin port in my 53 Rag. Just wondering if I can use stale air "manifolds" on the 1600 so I can still have heating and have an old style fan too?

Thanks

The 1600 is a wider engine so there might be some gaps or other fitment issues.

I had car with this done, it had stale air boxes with an aftermarket header replacing the original tube thru the heat boxes. The engine was a 69mm x 88mm with dual kadrons and a merged header. It was not a bolt on and involved a bit of welding and finesse to pull off.

The heat from this set-up was incredible, it really worked well.

I like this question, very out of the ordinary. Can I assume you're talking about the exhaust, not intake manifolds?

The fan shroud should not be a problem, they all have the same basic footprint from 36hp up to 1600 dual port so your fan and shroud should fit correctly on the dual port cylinder/head tins.

You might run into problems with the muffler setup. I seem to recall that the 40hp stale air mufflers are a little bit narrower where they fit up to the heads and possibly the heater box pipes. To fix the width problem you might be able to use a 1600 fresh air muffler and remove the fresh air mini-heat exchangers. Then, as the stale air heat exchanger pipes are shorter than the fresh air, you would need to extend them to meet the muffler. You could do this with stale air repair tubes, cut them to fit. Those pipes are smaller diameter than fresh air so you'll have to come up with some sort of clamp and gasket arrangement that seals them to the muffler.

Thanks for the reply guys.

Yep, I wasnt too clear, I meant the exhaust manifold.

Seems like it will be a lot of work, but worth it in the end

Are there any pictures of this done? Where 36 horse or 40 horse stale air boxes used? I would guess a J tube could replace the heater box and I wouldn't really care about picking up the small amount of exhaust heat at the back. I'm fairly impressed with the stock 36 horse heating system, the stale air works far better than its reputation. I was thinking with a 1600 single port myself.
