tunnel ram on a 383

[Mr71Demon]

Howdy. I recently bought a 69 satellite and it came with a Weiand tunnel ram the guy was going to put on. I think the motors out of a 67 satellite and it's pretty much all stock. I'm planning on just running the car on the streets and drive the heck out of it, but I really want to throw that tunnel ram on. I think it looks bitchen Is that motor gonna be able to handle it or should I not even waste my time? So if anyone has experience running a tunnel ram and any advice for me that would be greatly appreciated!

Keep the carbs small and it'll work just fine, Holley used to make a 450cfm vacuum sec , which worked great as a pair on a street tunnel ram, or carter 500 cfm also.

Do as he says and it will be ok. If anyone tells you it need larger carbs ignore them. Or just put and single carb lid on and use what you have.

It's pointless on a stock engine as far as performance goes, but yeah they do look cool if your willing to cut a hole in your hood...

It can work. The long runners are a plus but the huge open plenum isn't. Small carbs are the way to go to make it palatable. Holley still makes the 450 CFM "tunnel ram carbs". They are mechanical secondary with accelerator pump on primaries only (not double pumper). Odd carbs but supposed to work well.

Personally, I highly recommend Vacuum secondary carbs. Keep them small if you can. It helps a WHOLE lot if you have a taller gear 3.55 and up. I have two 750 Holley carbs, vacuum secondary, on a 440 with a 3000 rpm stall and 3.91 gears. I drove this daily for years (when I was younger). It was a blast to drive. I was pleasantly surprised at how well it ran on the street. You will need to play around with the accelerator pumps (both squirters and cams) to get throttle response where you like it. It is doable. I ran without a hood for a while and finally cut the hole after two years of constantly cleaning things on the engine. Biggest trouble I had was that the air filters would have to be replaced when they got wet (I drove around with spares).
Stay away from the single carb tops as they have terrible mixture distribution and are much harder to tune.
