Looking good..

What brand and model number is that intake?
I thought I heard a chirp from the 2-3 shift as well?

That's awesome! It sure sounds like the 318 loves the dual quads.

Offenhauser - I think the number was 5488??? Don't quote me on that... LOL. Anyways, it's the Offenhauser 360* dual quad for a early 273

Back in the 70's, I purchased an Edelbrock dual-quad Model D64 intake manifold fitting a 1964-65 273 I found in the display case of my local Salinas Dodge dealer (Bob Wills) for $50.00 (it was painted the correct 273 red engine color). However, I always ran a Holley 600 CFM double pumper on an Edelbrock Tarantula intake manifold on my bracket car '65 Valiant 4 door/4 speed conversion. Never used the D64. I was wondering if anyone is currently using one, how it is set up, and how it performs? Thank you. (Lost the D64 when I moved)
Hey Tim, nice to see that intake put to good use. Car sounds good !! Swingn’

Restore it, Dont part it!
I heard 2 chirps at the end around 60 mph that's one quick 318! I guess 318s will run! Hahaha see what I did there?

That is awesome man I love it! You gave me an idea for my 318 build whenever I get to it! Its amazing to me how you do what you do!
What rear gear sounds good.

They are high like 2.76 or 2.45 if I recall.
Enjoyed the quote "is it any faster with this, I don't know if it's any faster, but it isn't any slower",
7.25 rear end with 2.76's. I've been beating on this 7.25 for 5 years now... she still holdin' LOL
Yes, you started all this... LOL
People underestimate how good a 318 engine is.

Looks nice! I will tell you, though, that your 318 is NOT swallowing those cfm's up top there. I know you went to the dual quads and dropped ET, but that could only be that it was too lean before, and now you are getting the fuel. But that's ok, work with it if you're having fun.
...
not swallowing the cfm's I have on top either. In fact, it wouldn't use all the 770 cfm's that I had on it prior to the dual quads. As I said in a prior video, the motor will only pull what it's able to pull... But same as I told you, have fun and see what you can get it to do...
I'm considering using a D 64 on my newest 340 build. Is there a reason that you chose not to runs the carbs progressively?
2 reasons:
- This intake has a wall between the banks, so it's a long way from cyl #1 to #7 or #2 to #8.
- It was just simply easier for me to hook up direct with the pieces I had to work with.....
