They have the same block, so I am wondering if L27 heads (1993-1995) will fit with the LN3 intake, or can I use the L27 intake mani'* and exhaust mani'*?
Looks like I'm getting the Lesabre Limited rather than the Nissan, so in case I can't get the Park Avenue Ultra (current bidding is at $450 and I question if the trans is good because it was hit so hard in the left front) I might just convert to an L27 upper end -if it'* possible.
TIA,
Martin

yes the L27 heads are swappable to the LN3

But do I have to use the LN3 mani'*? I'd like to swap to the L27 mani'* too, since I could then use the L27 (maybe L67 later) TB, which is slightly larger than the LN3 TB I believe.

Manifolds bolt up to heads. I believe JR mentioned an extra coolant passage in the L27 over the LN3.

Ol blue, finding a 93 Upper end sometime soon?

Aw hell, go frankenstein, and put on a LIM/Blower....

Don, the Lesabre is a 1989, Limited, but without all the toys I would have considered part of the Limited package. It has no power mirrors, no power passenger seat, speedo with fuel guage -only two guages, no digital climate control, no power antenna, manual passenger seat (both of the other 1989 Lesabre Limiteds in the family have dual power seats). I guaruntee though, that the power antenna will be added as well as the full guage cluster, and possibly the power mirrors (I HATE manual mirrors in -20* weather).

Haha -I have my eye on a 1995 Park Avenue Ultra at the auction that was hit hard -aka not gonna be a fixer. I am thinking a nice L67 swap into the 1989 Lesabre might be on the menu, but I have to look at the car in person to verify the trans case isn't junk since the car was hit hard in the left front -from the pics it looks like the tranny **might** have survived, but only seeing it in person will tell. I know it'* gonna cost almost $1G for the car, but with my parents having a 1993 Ultra and my uncle having a 1996 the body and interior parts will be nice to have on hand (interior is the same color as the 1996).
I also have the original 16" Buick rims from my moms 1993 Park Ultra and will be putting some nice 225/60/16 rubber on there along with the FE2 sway-bars from the 1997 SSE if they'll fit and Poly end-links. Would make a hell of a sleeper if I got the L67 in there.
