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!!
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
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.
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...
