BBCRedline This is based on my 540 with afr 335 cnc heads at 720 or so hp without it. I bolt on the tunnel ram and I could see up to 100 hp gain. Maybe 75 or 105 or who knows. I will have to dyno it both ways.

against all odds He said 100hp? Under what specific conditions?

BBCRedline I have thought of the cutting the hood thing. I have a lift off hood Harwood hood, so I can run the thing and see if I like it before the opening has to be made. I was just on the phone this last week talking to Joe Sherman about the whole tunnel ram thing. He likes them and says they can be a magical 100 hp add on. I will not be buying any demon carbs, basically because they are out of business and I owned one once and that was enough.

Have you also given any thought to the big hole in the hood of your Camaro that's gonna be needed?

Starting is not an issue. But you want to let the motor run for a while at a rised rpm above idle to allow it to warm up.

Hold it at around 2000rpm so it can warm up.

When some heat gets into the runners its ready to drive.

Functional chokes and fast idle, help.

lg1969 Mine starts up on a dime. I use the choke setup on the rear carb., only.
Just google tunnel ram 406 and you see what I mean.

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

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

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

NOlowrider 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.

lg1969 My tunnel ram 406sbc jumps or twist the chevelle every time I tap the gas pedal, and I love it every second.

Jake_Dragon Its not a BB but I have one on my Vette. I am surprised by how well it runs on the street.
05-13-2011 01:10 AM
67-4-fun 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

DoubleVision 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.
