Steering box header clearance issue

Howdy. Its been a long time since I've been on the site (kids, work, etc), but I back working on the 69 and ran into a snag.

The car has a BBC 454 in it and its crowding the space for the steering box. I purchased a CP500 to replace the original box. However when I went to install it, I found I was short a good 1/2"-3/4" and needed that much additional space between the frame and header to mount the new box.

Wondering if anyone has had a similar problem, and what solutions yall came up with to keep the big block and have power steering.

Always appreciate the help. S/F.

Re: Steering box header clearance issue

Do you have the proper Big Block engine stands and transmission cross member?

I have an IROC box with Dynotech headers and a BB. Almost touches. Been that way for 10 yrs.

Re: Steering box header clearance issue

My solution was to install the proper big block frame stands/engine mounts, Headman headers and a slight file job on the side of the gear box

Re: Steering box header clearance issue

Thanks for the feedback. I am fairly certain that i replaced the motor mounts with the correct type for a BBC when I pulled the 327 (long time ago). As for the trans X-member, I will have to verify later today. Not sure off the top of my head.
In the event that I am not running the correct motor mounts, would swapping them to the correct type adjust the motor position enough to give me the needed clearance?
Is the Iroc box close to the same size as the stock box?

l - I believe these are the mounts i ordered/installed when i did the engine swap.

Many thanks.

Re: Steering box header clearance issue

Just an FYI BB engines in our Camaros are offset approximately 1/2 inch to the passenger side. Installing the correct motor mounts and trans X-member is crucial when headers are on the car. Measure from the air cleaner rod in carb to passenger fender. I believe you should get 24 inches. I don't have my BB anymore so I can NOT verify the actual measurement. Perhaps someone with a BB can check this for you.

Re: Steering box header clearance issue

You can run a string from cowl panel center crease to header panel crease and if air cleaner stud/nut is over to the pass side, then yes, correct frme mounts were used.
Keeping driveline angles satisfied, the proper BBC trans crossmember would be needed.
Are boxes same size? Measure with tape measure and maybe, make a model and see if it would fit.
Some earlier installs, say 20 years ago, had to dent tubes for clearance
You could change over to rack-and-pinion steering?

Re: Steering box header clearance issue

Good advice on the mounts.

I would strongly suggest not even thinking about R&P with a stock sub.

Re: Steering box header clearance issue

There's not a lot of room when you put a BBC in a 1st Gen Camaro, so the factory BBC mounts shifts the motor slightly to the passenger's side. That works with cast iron manifolds but many aftermarket headers will give you fits. Some brands come with a factory-slight "dent" where the third primary comes into proximity with the PS box. I've got Hooker Competitions on my car... 2" primaries, 3.5" collector. When we installed them, we added a few Moroso motor mount shims to give it a little extra lift... maybe 1/8"-3/16"? Worked out OK (see pix). They came with the dent. Use a 1" deep socket with a shop towel wrapped around it to tap in a dent if needed. You won't lose any horsepower.





Another option is headers with a different design, but be prepared to pay a bit more. Dougs, Hooker, and Lemon all make headers that have problem tubes sweep up, over, and down.

Re: Steering box header clearance issue

Thank to all of yall for the suggestions. Took a measuring tape and the air cleaner stud is less than 1/8" off center. This leads me to believe that i am not running the correct BBC motor/frame mounts. That being said, I will probably pull the motor when the weather breaks here in CO, put in the new mounts and trans Xmember. Again, thanks for the help. S/F.
