Technical Mopar long ram intake and carburetor questions

Eary to mid 1960s Fords used them. I've got a couple somewhere.

 

...a block heater could be added into the mix.....

 

Billy lane just released a new video of welding up a huge hole in a 1946 case, you can't get more contaminated than that, it's a pretty informative video.

Going tomorrow morning to take a look at the treasure. If it's as nice as he says, I'll get it.
It's gonna clean out my poor little piggy bank.
I don't care. LOL

 

I had a set of the long tubes with carbs and linkage forty years ago, I don’t remember selling them but I know I don’t have them now…

 

@oldiron 440
I share your grief over the unexplained loss of your long tubes.

 

These are adapted to a Lincoln engine. It's in my friends Mutz jet.

This is actually a hell of a deal I think, I wish our dollar wasn’t so worthless right now…

 

I agree, that is an exceptional deal.

 

Got it.
Really is in very good condition.

 

I think I learned they made power to around 4500 rpm and sold or traded them for race parts.

 

I see. I thought you meant maybe they got stolen. Selling them for race parts is way bedda. No sympathy then.

 

A better performer is a tunnel ram honestly. I debated many times on the choice for mine, I went tunnel ram for performance and price. But whatever floats your boat...

 

I have massive intake envy!!

 

I seriously doubt that this would be any issue at all. Let's assume that each tube has the volume of what, two, maybe three full cylinder charges? If it's three cylinder charges, it's going to take a maximum of six crankshaft revolutions to consume what is in the long tubes. At 2000 RPM it's going to take 0.18 seconds to consume what is contained in the tubes. Less than one fifth of a second. Your car is not going to keep accelerating for any discernable amount of time after the throttle butterflies slam shut.

If you have any information, real or imagined, that conflicts with my estimate, I'd like to see it.

 

Only bad thing I see would be valve maintenance. No way to pull the valve covers without pulling the intake. But for the wow factor, you can’t beat’em.

 

With hydraulic lifters how often is one having to pull valve covers?

 

Also do some actually believe there is a perceptible delay in throttle response when letting off the gas?

 

Tunnel ram intakes are badass. They make power. But they didn't come around until the late 60s. And performance is a relative term. A tunnel ram can't make torque down low like this thing does. And like I need it to. It's going into a 4,000 lb car. LOL

 

I can't detect any delayed deceleration in any of the dynamometer videos for this system.

Not being able to remove the valve covers did cause me to take pause.
But only for about 5 seconds.

 

Holley carburetors fit. I checked both 650s and 750s.
Spacer will help, but they fit.

Velocity stacks from my '70 Roadrunner that got stolen in 1978.

 

Some of you guys take this crap way to seriously.

I'm sorry you are unable to distinguish between facts and a BS made up story.

 

Sarcasm is basically indistinguishable in a post.
Gotta tell us when you're lying.

 

I'm following along as I have a set of rams but little else.

But they need to go on the car. Need.

 

It's easy to get emotionally involved with this intake manifold.
Sometimes, when people look at it, especially if they're seeing one for the first time, they make sounds. Like they're having an orgasm or something.

 

Funny, you mention that about people making sounds and gocking at it. though The car didn't run as good as it did with the single 4 My friend left those crossrams on because he got bunch of attention from people. He would fire it up at a car show and just let it idle forever with the big huge cam and no compression and people thought it sounded awesome.

 

Gotta make it run good, too.
But the audio visual thing is definitely part of it. I love it. LOL

 

Hey, Ricky;
"Tunnel ram intakes are badass. They make power. But they didn't come around until the late 60s. And performance is a relative term. A tunnel ram can't make torque down low like this thing does. And like I need it to."

Not exactly... Depends on the tunnelram - if it's a std aftermarket type w/a big box - you're correct.
If you make it yourself, you can design it to "hit" where you want, length n dia of ramtubes plays in of course, but the big thing is the volume of the box. A guy by the name of Dick Datson, in ~'69/'70 found that volume changed where the manifold "hit", & the "hit" worked for ~ 3000rpm(iirc)+/-. He got it to work as low as ~1500rpm, & as high as ~7000rpm, on the same Stude 259" engine, although the big box was rather soggy 'till high rpm. He used 2-2bbls, 'cause that's what a small engine could use. Volume for low-rpm was literally no more than space needed under each carb for the throttleplates over the tubes, & a very shallow path between each 2bbl opening.

Yes, I also like the Chrysler side-rams. Saw a pic of them adapted to the Packard v8. Way too much cool stuff out there, not enough of me, time, $$$ to even begin to enjoy everything... .
