Can't get my Mac mid-length to slide in

**greenvilleTA** · 02-03-2007, 07:17 AM

I'm dying to crank my car after finishing my 383 build up, but the only thing stopping me is getting the passenger side header back in place. No matter what I try, I can't get it in place. I've tried it through the bottom til I was blue in the face and also took my valve cover off and tried from top. What the hell is going on??? I had a shop install the headers and ORY before, so I don't know how they got them in. Do I have to loosen the motor mount and jack the motor up???

Ground the tab off the block and it slid right in...

you would have had to jack the motor up i think, but i remember reading about cutting off the tab on the block

i was soo close to buying MAC mid-length's but i decided to save the little money i had

I can't understand why you had trouble with the passenger side is usually the easier of the two. Did you have the starter pulled?

That's what I was thinking also. The passenger side was actually easier on my LT install. It's the drivers side I had to whittle on the casting tab.

Starter on...starter off...I tried everything. The block is a new 2006 LSX block, which probably doesn't make a diference, but until I got the tab off, the header would not go in, no matter how hard or long I swore at it. I got the drivers side in place in about 45 seconds. After the tab was removed, only took about 2 minutes. I don't know what the deal was, but it wasn't going in without some kind of intervention.
I did get it cranked last night and all sounded good, so I guess I need to update my sig...
