2024 folks...we can't place pics in the write ups? Yikes.

[FarmerJon]

Glad to see you got it done!

 

How does it run, compared to before?

I can't figure out how to place pictures into the article where they belong.

As I mentioned, I have to finish up the exhaust before I can tune it up.

Thanks for posting. Very nice, considered and well engineered work. Your '34 is particularly suited to this tasteful upgrade. And, in theory, it should deliver improved performance and not just looks. I look forward to seeing the performance outcome. Art and engineering combined...worthy of the art deco ethos around automobiles.

Thank you, appreciate that.

 

For a single atmosphere the original carb was perfectly fine. The car doesn't need any more flow than the original carb, at least not in a meaningful way. Economy, perhaps all the rest in negligible by todays standards.  The exhaust is where something can really make a difference. Anything else is accomplished by speed parts inside the engine...pistons, crank, valves, decking, porting and fuel. Then there are some gearing that can matter. If you want to go faster, get in a modern car.

Yeah, the stock exhaust is a cork.  So are the stock valve guides.  Anything else done without addressing them is less than optimal.

That thing is primo! Thanks for sharing

Sniper...... So, what do you do about the stock valve guides?

[Sniper]

You trim down the portion that sticks in the port. The freewheeling Tony Smith has some info on his Facebook site

My answer was a little lacking in detail, I was on thee road using my phone.

 

Here's the valve guide picture from Tony

How long a guide do you need?

 

https://www.speed-talk.com/forum/viewtopic.php?t=19767

 

Assuming a 218/230

 

length * 1.15 * stem diameter =

 

4.845 * 1.15 * 0.3405 = 1.89"

 

Stock guide length is 2.813"

 

So almost an inch can come out of the guide length, all of it from the port window.

Sorry to be a duffus, is that a progressive linkage? Or step down?
