Incorrect specs?
Been looking around and what I've read suggests the L27 came with 220 ft/lb torque, not 225.
Even so, I'm looking for some specs I can never find a solid answer on...for example:
Did the L27 come with a compression ratio of 8.5:1 or 9.0:1? My manual (I'll have to recheck CHILTON as well) says 8.5:1 until 1995, then itr was 9.0:1 for NA 3800'*.
Also, whats the gearing for the L27? Let me know if I'm correct:
1st = 2.97
2nd = 1.57
3rd = 1.00
4th = 0.70
Final drive ratio = 3.06:1
Last but not least...weight of a 94 SSE is 3587?

BTW! The Engine has nothing to do with the Transmission gearing!
Depending on what transmission you have & model of Bonneville (SE/SSE/SSEi), depends on what final drive option you got.
Pontiac Bonneville Transmission Final Drive Ratios:
1987 > ME9 > 2.73R
1988 > ME9 > 2.73R / 2.84R
1989 > ME9 > 2.84R
1990 > ME9 > 2.84R
1991 > ME9 > 2.84R
1992 > M13 > 3.06R / 2.97R / 2.84R
1993 > M13 > 3.06R / 2.97R / 2.84R
1994 > M13 > 3.06R / 2.97R / 2.84R
1995 > M13 > 3.06R / 2.97R / 2.84R
1996 > M13 > 3.06R / 2.84R / 2.93R
1997 > M13 > 3.06R / 2.84R & MN7 > 2.93R
1998 > M15 > ?.??R & MN3 > 2.86R & MN7 > 2.93R
1999 > M15 > ?.??R & MN3 > 2.86R & MN7 > 2.93R
2000 > MN3 > 2.86R / 3.05R & MN7 > 2.93R
2001 > MN3 > 2.86R / 3.05R & MN7 > 2.93R
2002 > MN3 > 2.86R / 3.05R & MN7 > 2.93R
2003 > MN3 > 2.86R / 3.05R & MN7 > 2.93R
