Tunnel ram on a street bbc
I have been thinking about running a weiand tunnel ram I have on my bbc but not sure which 4150 carbs to get?

Tunnel ram on street
Engine size and build info? Run a couple of 500 cfm Edelbrocks (#1404) or 600 cfm Holleys (#1850).

Get a pair 600 cfm VS 1850's Holley. there are other guys out there that got great result with the 600 Holley. It's not nessary to run two electric chokes. You only need one setup for easy cold starts. Make sure you install balance vacuum line for uniform secondary operation. Hope this helps. :thumbup:

I am about to put a tunnel ram on one of my BBs with two 500 eddies.I just like the cool factor of them but have a friend running one and that rat honks.Let us know how it works out for you.
You hear a lot of down talk about them and a lot of good but the way I see it if your are not willing to do some work tuning it's not worth the effort and I for one love a good challenge.

I`d use a couple of Road Demon Jr. 525`s. They have a nice look to them plus they have annular boosters which is far better than any straight leg or down leg booster.

even tho it is a BB, becarefull not to over carberate, seems thats one of the biggest mistakes guys do when running a TR for the street is over carb the engine.. As mention, two 600 VS or even two 500 VS should do just fine

Its not a BB but I have one on my Vette. I am surprised by how well it runs on the street.

My tunnel ram 406sbc jumps or twist the chevelle every time I tap the gas pedal, and I love it every second. :D

I ran the Weiand T-ram kit from Summit and I loved it. I had no problems. Never really even tuned the carbs, pretty darn close out of the box. Just make sure you have enough stall (3500 for me) and mine liked the timing locked out. 2 600 Holleys, no choke and no vacuum pods. Ran great, I just removed it for a blower.

Thanks for the input. I wont have to worry about the torque converter as I have a clutch.

NOlowrider 05-13-2011 10:28 PM

Even better. I think you will be fine. A small diameter distributer might be needed though.

How do carbed tunnel rams start though?

Jake_Dragon 06-10-2011 02:46 PM

Mine starts better than the single carb 350 in my other hot rod.
