Holley Street Dominator 340 version???

[604]

Did they ever make a Holley street dominator with the larger 340 port dimensions? I am thinking they did not, but was not sure. Thanks!!

 

[1wild&crazyguy]

not that I know of.
The runners of the street dominator are '318' small all the way to the plenum too..fwiw

Thanks,
That is what I thought. I have one sitting hear and you are right. Would do no good to open it up to 340 heads. Shame they did not make one with 340 dimensions. I guess a person could always get a Edelbrock Torquer II.

Holley made a strip dom which has the larger ports but no heat riser ports for the exhaust intake heat, why its called Strip Dominator. In the old days only strip cars ran unheated intakes mostly

Yea,
Mopar makes that one new. To modern looking for a car that I want to look like it would have in 65 or 66

Offy made some single plane divided intakes, like the early 60's cars had. Those were in both port sizes. Ebay and here is your only hope. The old eddy 340 torker has larger ports and the TM5 were larger yet--deeper.

Or the LD340 dual plane. Holley street dominator isn't bad and ports could be opened up a bit. Ports are small but short and no 90 bends, flows pretty well and the smaller ports speed up airflow for better low/mid range power. With the right cam it still be good for 6,500--maybe 7,000 rpm. I ran the holley, I liked it, really think it pulled better after 5,500 then the RPM intake. RPM did feel better from a stop but I didn't have a good converter back then. With a 3,000 stal converter the Holley would work great, imo, even with the small ports.

I run the small port dual quad D-64, D-66 intake(forget which one). Small ports don;t seem to hold the engine back, can hit 6,500 easily with 3.91 gears.

Thanks,
I have one of the TM5 intakes laying around also. Looks like a great intake. But did not come out till 1971 I think. I have been thinking about the Offenhauser 360. Summit still sells them new. Just not sure what year they came out.

Well....for what it's worth, Chrysler made a single plane cast iron four barrel intake for the 318 from 67 to about 76 for marine applications. They don't have any crazy marine crap on them and are rumored to flow VERY good. You see them on Evilbay from time time.

Use the street dom. as intended and be very surprised at how well it works over the other intakes of the time. Do remember that big block intake shoot out between intakes? The old Holley design won. Why? I'd gather since Holley is into carbs, designing a proper intake to compliment there excellent carb is the min. they would do.

Old guys will tell ya, the Holley equipment was the stuff to have.

The MoPar intake is a updated version of the Holley. A bit taller with more plenum and runners slightly raised. It's a winner.

The TM5 is best for strip use, 4.10 gears or better still 4.56. Its best from 4,500 to 7,000. The 340 torker was the street/strip intake, was good to just over 6,000 maybe 6,500 but came on earlier, say 3,000 ?

Offy is old school, I got nice M/T valve covers to match the older intake, looks really cool--no pictures, gas stations took all my money this summer.

had a holley street dominator on my 73 340 challenger back in the early 80s....removed it and but a holley strip dominator on it....car pick up 4 tenths and 4 mph in 1/4...

never saw the street dominator again....probably is a beer can somewhere...

I looked back at this and I don't even know why I posted what I did. You wanted something for the large ports and I posted about a small port intake. Sorry bout that. I had a long day.
