    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, OBD1 Conversion...for now, future plans include a 3900, T04E-46 (Knock-Off) turbo (For the 3100, ~T61 for the 3900), and a F40.

    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
