I need a couple of 850's for a tunnel ram application. 500 inch hemi, unported heads, .600 flat tappet, street/strip deal. Summit list two 850's. Not sure of the differences. Can anyone tell me which is better suited? I realize it will need changes either way. https://m.summitracing.com/parts/hly-0-9380https://m.summitracing.com/parts/hly-0-4781cThe choke/no choke is the only difference I notice

The choke/no choke is the only difference I notice That's the only difference I see too although I didn't look at them very long. I'd probably run the chokeless carb but it'd be better to have the whole choke tower milled off. If you can spend more, the custom built carbs are nice too, there's no extra cost to have them built for your combo through a place like Summit. I had 2 Quickfuel 750's on my low deck TR, they had the wedge shaped TR floats in them and were pretty much spot-on right out of the box.

You want to get something with adjustable metering for a tunnel ram, they need the idle circuit calibrated different that for a single carb app. Quick Fuel Q-850's or Q-950's would be my suggestion if you want to keep cost down, otherwise custom from a quality company would be my suggestion.

Mark, im going for an old school build/look here. What would it take to make a dichromate carb work well in this application? I know it sounds strange, but i really prefer a traditional looking carb for this build.

I wouldn't hesitate to use the 9380 on tunnel ram, you might have to adjust the idle mixture screws and maybe do some jetting for your area gas and altitude How much tuning and modifying are you willing and capable of doing? Are their better ones out there, sure if you want to try them or have a custom set made

I would not even consider anything that has a choke horn or isn't tuneable.
Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston
