305 V-6 with dual Strombergs

[Corts60]

Thanks Dave!

I think that LMC actually sells a header for v-6's. This will be one cool motor in my book

The only headers I can find are the I-6 headers. Not to worry though, I just sent a check in the mail today for the V-6 header flanges from thunderv12.com and as soon as I get them, I am going to start building my headers.....

Hopefully in the next 2-3 weeks.

Ooops, the I-6 headers were the ones I saw...my bad

Nothing yet, thanks for reminding me. I am going to call them today. I am not very pleased with thehotrodcompany.com's service. They keep saying they are waiting for a shipment of new Y manifolds, but I am about ready to cancel my order and go through vintagef*rd.com.

I am still up in Bellingham, WA for work and I hope to be home by the 4th of April, I'm sure my header flanges will be waiting.....

I'm ready to get some work done!

[4dranch]

I hear you...I was just courious

[protrash64]

I thought we'd be seeing the paint burnt off the bottom of your hood by now!!!

[Corts60]

OK, I cancelled my order from the previous company. Looks like I am going to try my luck with vintagespeed.com:

This one looks lower so I might be able to clear the hood......maybe.

[jbgroby]

Corts,

I have a friend who desperatly needs the carb air breather you have in the OEM carb. OIL BATH STYLE, If you still have it he will buy it from you. Please contact me if you have it or not. Thanks

jbgroby@charter.net

[Corts60]

OK. I'm home, and here are the carb's and header flanges:




To my unfortune, I have to drive my '60 daily for the next couple weeks while I get my '76 Nova SS on the road for my daily driver...

What do you think about the set-up?

[texanidiot25]

Will dual carbs help breath air when their choked down back to the same size holes as the regular single carb?

But, for looks, saweeeeeeet.,

[4dranch]

Cort..That looks so freaking cool....
Whats the overall height???

[19GMC63]

looks awesome.
I too am curious on the height and what your going to do for an air cleaner(s).

I'm not sure, I've never done it before......but you can ask 60 years of hot rodding......

[Corts60]

OK boys....The first pic is the stock one barrel and oil bath air filter at just over 8". Forgive the pic, it's night out.
The second pic is of the assembly without the adapter at 9.125"....
The third pic is of the assembly with the adapter at 10.375"....



If I go without the adapter I have to drill and tap a center hole in the intake, if I go with the adapter, I will have the carb's sit just outside of the hood...
And I have no idea what filter I'm going with yet......HELP HERE!

[jonzcustomshop]

I would try to keep it under the hood if possible, without the adapter how much room to the top of the hood?

if not you might try that big ford truck scoop from 60-63 that they used on the superduty pontiacs, I think they might repro them...they would look period correct.

If you are ever in the missoula area, we could run up to kellys wrecking yard, he has a few of those 60-61 gmc hoods, I just think the shipping on one of those would be huge.

It's old hot-rod technology. As long as the airflow doesn't get disrupted, velocity will increase to provide the needed air. One thing that was done was to place a riser under a carb, old bottle jack bodies were used since they had a flange on one end. Increasing the air speed entering the engine shortens the time needed for filling the cylinder and allows the engine to accelerate faster.

[jonzcustomshop]

so would the optimum shape of that adapter be a V to disrupt the air flow the least?

That's what I was thinking too...The first manifold I wanted was the Y manifold pictured on the first page, but turns out those are on permanent back-order....

Sorta like a tunnel ram intake eh?

A wye would be best, which is a vee with a leg. You get tremendous torque right off the bottom of the throttle. You do end up gasping for air at high rpm. But with these heavy trucks torque is what gets you there. A friend in high school had a 261 six in his 50 Chevy car, still had the one barrel carb with a tube under the carb. He could hook it up good enough to lift the front wheels a foot off the ground.
