BBC headers hit steering shaft

I have a stroked 454 in my 70 Chevelle, and I am running 2" headers. driver side header tube is banging up against the steering shaft, and I just can't settle for the ole "take a hammer to it" solution. is there ANY way to resolve this without having to beat the ***** out of my coated headers?? heads are brodix BB2's. thank you

Re: BBC headers hit steering shaft

You can dimple the tube with a split in half piece of Pcv tubing. Around inch and a half works. Mite have to gently pry the shaft over to slide the piece and place and then with a long piece of 2 by 4 or brass drift pop the shaft so the PVC dimples the tube just enough for around .080 of clearance is what I would shoot for. That method makes a nice clean dimple in the right spot. It's either that or you're going to have to modify the tube

One word, Lemons. Call Dan and he will make you a pair of headers that will fit and not hit anything. They are works of art! Seriously.

If your Brodie heads are raised port, he’ll factor that into it as well.

Re: BBC headers hit steering shaft

Consider Shimming the Steering Box to move the steering shaft away from the # 1 # 3 # 5 cylinder header tubes,

1 washer at the top front and 2 washers at the bottom front.

I had previously Dented a little any of the Header Tubes required

Re: BBC headers hit steering shaft

Well you pretty much have two choices. Either dent the headers or get a new set of headers. Lemons are top quality and will clear. Maybe some other brands will as well. Dent your existing and send them for recoating or get some Lemons.

Re: BBC headers hit steering shaft

I put a spacer under the motor mount to lift the engine up just a little higher. Worked perfect.

Re: BBC headers hit steering shaft

Why not move the shaft over? There's about 3/8ish clearance you can create by unbolting the column lower plate and moving it over which in turn moves the shaft over. yes things changes a few things but its cheaper than a 1500+ set of headers.

Re: BBC headers hit steering shaft

If you have to ding them it is possible to touch them up.

Can you elaborate more on moving the column over. I must be over looking something as I have the same problem. Thanks
