  • L37

    I'm debating on doing an engine swap or not. Well a L37 engine fit and bolt up in a '95 cutlass supreme sl?

    if by L37 you mean HO Northstar, it has been done before in a W, but it's a LOT of work...
    1995 Monte Carlo LS 3100, 4T60E...for now, future plans include driving it until the wheels fall off!

      I decided to keep the lq1 in it. It will be unique when I mod it.

        yeah that northstar monte is for sale right now too over on Mymonte. com

        FYI if your looking to mod it. i am parting out my DOHC. i have the discontinued FFP under drive pulley and the full intake manifold and TB set. these are the parts i used to run my 14.9 and 14.81 at the track. and if you ever swap to OBD2 i can do pcm tuning as well :-)

        but enjoy the DOHC i already miss mine. it sadly wasnt cost effective to retime my engine with 225,000 miles and rebuild my trany when i can do a 3800 swap for much less and make more power.

        the top three mods that did the most for me were:
        -Tuning
        -Intake manifold/TB porting
        -3.73 gear swap
