I've got a line on 3 Holley 94s. I'd like to use them on my 292 y block if they will flow enough air. Will they work fine for a 3x2 on a y block or should I wait till I can afford strombergs or use Rochester 2gs. I'm not going for power more for looks a d drivability
I guess I was told the wrong info the whole time. I was told the stromberg would flow more and over all better.
I ran 3 stromberg 97s on my 312 before I went with a 2x4 se up they flowed more then enough air even with the worked heads. The holleys will be fine in the 292, unless it is cammed up they may acually be more carb then is necessary. But once dialed in they will work just fine.
Thats all I have ran on both of my tri-carb set-ups. Once dialed in, they work near perfect. NO complaints out of me.
Not trying to hijack but on the tri power for my 56. Its just going to be a cruiser so I thought. Strombergs would be cool. The 6X2 for my rod not sure what carbs to run
Use your 94's. They are the best for a Y-block. I ran the same thing on my 292 hooked up progressively. Block off the outer power valves and use a stiffer one in the middle carb. turn and a half on the screws seemed to be the best for mine. Ran like scalded dog and sounded great. All the best, Tim
The stock carb that came on a y block was a version of the Holley 94. An ECG-5 in 1955 and an ECG-6 in 1956. I was actually speaking with Dickster last night regarding the ECG-6's and he gave me an education. I'll be running three of them on my Edelbrock tri-power manifold for an Olds...the reason being that in the 1957 Edelbrock catalogue, it actually states that the manifold was designed for the Holley 94s instead of the Stromberg 97s. If they're good enough for Vic, I'm sure they'll be good enough for us!
The 3 Carbs will flow about 510 CFM at 3 inches of vacuum. That's the equivalent of a 361 CFM at the 4bbl standard of 1.5 inches. A 500 Holley 2 BBL flows 353 when you use the 4bbl standard. So it should run well but will be restricted on power. The 94 means .94 venturi, There are related carbs in the Holley AA seriecs which have larger venturis and flow more. There is an ECW (may also be a 2110) 1 1/16 Venturi, 1 3/8 butterflies, 2 1/4 choke throat - 205 cfm. ECG- 185. A 3 210 CFM would equal a 445 CFM 4bbl which would be about right for what you describe. Hoop
I'm running three 94s on a 350ci Y-Block, it will rev quickly and run a 1/4 mile just under 10 sec. (see avitar) I think they work fine, even with a "big" cam. (only saw a minimal advantage with a 750 four bbl)
I can not help but wonder why no one ever uses Rochester 2CG's on Y blocks. They are from the same era and are in my opinion anyway a much better carb. Y blocks are not that different in ci. than early Chevrolets. All you would need are 3 to 4 bolt adapters or drill the manifolds.
I have 3 Rochester 2gs that I was planning on using but my offy manifold is for 3 bolt carbs. I would need the adapters to run the Rochs. I don't really like the look of the adapters. That's the only reason I decided against using them. I've heard they are great carbs.
I am not sure about 94's but I read in an old 348/409 book that although the 97's flowed less air they mixed better than rochesters and dyno proven for more power.
They don't look as vintage, I think. I have 3 chromed 97's waiting to go onto my edelbrock intake for the 292 in my f100. Pretty excited about it.
I agree, hell, if there good enough for the y block guru I should be fine! To the op, do you have any pictures of your setup?
Porkandbeaner how does the 2x4 perform? I have this set up that I plan on putting on my built 292. Posted using the Full Custom H.A.M.B. App!
