My headers in my big block '69 won't seat because they're resting on the PS box. Here's my question:

The PS Box has two raised "humps" (for lack of a better descriptive term) that run lengthwise down the passenger side of the unit. This is what the header is hitting and not allowing it to seat properly. Is this casting flash (from the mold) and can I grind it down to be the same height as the surrounding case? Or will I strike PS fluid and start cussin'? I've never had the unit apart to look inside so I don't know - anyone have any experience with this?

I am not sure which humps you are talking about but don't grind on the steering box. Do have the correct frame and motor mounts and especially the correct or modified crossmember. If you don't get them before you go any farther.

I have some motor mount info on my page. Click on my first gen suspension page below, then find my engine page and click there.

Thanks Oger - which Hooker Super Comps did you get that fit real well? The 1 7/8" (PN 2111), 2" (PN 2205), or the 2 1/8" (PN 2285)? Hooker says the Comps are supposed to fit and are much more reasonably priced but I haven't heard anyone say they've had luck with these, just the Super Comps.

I tried most of today to try and get those dang headers to fit - first I shimmed up the driver's motor mount about a 1/4" which fixed the tube hitting the PS box up top but then the header hit the pitman arm at the bottom - no way I could have made left turns.

I got the frame mounts for a '68 big block (even though I have a '69) from CInd. and the poly motor mounts which measure the correct 1 3/4" from mount hole to block surface. I thought you could use any '67 to '69 frame and motor mounts for a 1st gen. as long as you stayed within the same year but maybe you can't. I'd return the frame mounts (I've heard you say they're incorrect before) but it's been a while plus I had to elongate the frame mount holes because they didn't line up properly in the first place, thus I "damaged" the mounts and can't return them. I could really get off on a rant here about quality of resto parts but I'll restrain myself.

David, great page - I've been there before. The only other info I'd love to have but haven't been able to find is what the exact measurement of the correct frame mounts are. Then I could see how far mine are off and determine whether I could fix them. I really hate having to get new frame mounts, motor mounts, and headers since I already purchased this stuff and it's not returnable any more (I've never been able to test fit headers and not scratch them up to the point where the parts places won't take them back) but it looks like I may have to.

Thanks for your help

I just wanted to add that my original PS box did not have the Humps that you are speaking of, but my AGR, and other newer boxes do.

TJS69 - hmmm...I wonder if it's not the original box? Anyone know if there's somewhere I can decode the part number?

68 and 69 frame mounts are not the same if you use 68 you must use everything including the short waterpump and acc. mounts. Make sure that you redrill the crossmember to shift the trans to the pass side that seems to help as much as anything and is not hard to do. When the car gets out of the body shop I will measure the frame mounts they are the correct 69s

Jon I had the same problem as you. I put a big block in a small block car I had bought, and the first thing that I ran into was the header and the steering box. I used small block frame mounts with moroso short solid mounts. The power steering hit the header so since I would not be driving the car very much I used a manual gear box. One thing that I was told would not work was the clutch linkage, but since I used the small block mounts the clutch linkage worked off the small block set up. The car has been up and running for a month now and is a BLAST to drive. This is my first big block car but the swap was pretty painless.
