    8 bolt flywheel - same for all blocks?

    I have an 8 bolt flywheel from an 86 block. Can I use this on an 89 common block without issue? Thanks!

    Masi 16V is different, Lotus 16V is different but all 8V 8 bolts are the same as far as I've seen...

    2.2 Carb and TBI flywheel is its own unique unicorn... the bolt and dowel pin 'pattern' for the pressure plate is smaller than any other 8v including 2.5 TBI. Just something to be aware of.

    In other words, turbo 8v are the same. Non-turbo will not work with turbo clutch/pressure plate.

    Turbo 8v and 3.0 V6 are the same also AFAIK.

    Seeing what I wrote I should have worded it differently. The 2.5 TBI also uses the same 'bigger' pattern flywheel like the Turbo 8v applications.
