Anyone ever checked with a professional machinist, or internal engine parts company to see what the limits are for a 3.8L to be bored and stroked.
If so, please list which company or with whom you spoke with.

Do not reply if your brothers' girlfriends' Sisters' Cousin, on his mother's side who knows this guy who is friends with a mechanic told you it was xxx.

Looking for these bore possibilites:
3.83, 3.86, 3.925
And these stroke possibilities:
3.67, 3.92, 4.045 (or 4" even)

 

blig, if you want technical answers you are on the wrong board. an answer to this kind of question would be answered a lot quicker and more accurately at the other message board
i aint putting this board down, as you see i am here myself, but from my experiance, i tell you what i tell you.
good luck

 

Yeah I noticed that, seems I'm the resident mechanic here? Oh well, worth a shot. Never know.

 

As I do agree with 1fastV6, this board is more for the LT1s and LS1s. Atleast in technical advise. May even try the advanced section of the board, but I don't know if it really belongs there.
