Here'* the best pic I have of the stock L27 manifolds from the parts car for comparison:




Quite a bit different.

Doc... your setup looks yummmmmy!

Lemme see if those would even fit... *walks outside to grab manifolds from '87*

1) The '87 has those manifolds. Exact same.

2) Port spacing and bolt location is the same w/ my '87 and '93.

3) Those are not a performance peice, They're smaller than the '93'* pipes and not mandrel bent.

there is no o2 bung on that set of "manifolds"[/img]

Yes there is, It'* just not visible in the pic.

Bummer!!! I thought the rear mani looked kinda stock, but the front header looked like the real deal. Too bad they are smaller pipes than the 1993 -other-wise they'd be a cheap header for the L27 and Series I L67.

Damemorder -since you have a set off, would you be interested in taking them to an exhaust shop and having them throw a set or two together -or at least get a quote for a set in aluminum and SS. If I can get my set off my 1992 I'll see if I can get them over to Alex Exhaust for a quote there. Although I don't have a Series I 3800 myself, I still have alot of fond memories with them -and will probably be making more someday.

Man I want some headers bad. That would improve the look of the engine big time as well as of course performance but not big time Im guessing. Id wrap em up good.

Depends... You think the local rednecks who can't even put on a muffler without leaks can design headers?

Ahh wish those were mine, I just found a pic to illustrate. March area is when I'm getting mine done
