Why is it that half of the stuff I see on the 3800 L27 says 9.0 to 1 compression when its really 8.5 to 1 ... The only change was in 95 with the L36 at 9.4 to 1, and thats listed correctly...

The 3300 V6 and the old 3.0V6 were 9.0 to 1 compression...

The 3300 ( And I have seen messed up numbers on this engine as well ) made 160 Hp and 200 Ft lbs...


Maybe we should get some flat tops for an L27 and see what we get

I found this article from Car & Driver July 1993, about the middle of the article, mentions compression ratio up a half point to 9.0:1

I'm still not so sure that compression ratio bump is true... I have found so much conflicting info on that.... I have found various service manuals that list it as 8.5 to 1 and some as 9.0 to 1...

I have even found servive manuals that list the L36 as 9.0 to 1 when its actually 9.4 to 1...

we need to be able to compare the heads and pistons of the LN3, L27 and LG7
