    Block Question

    Gotta question:

    Will a 3.1MPFI block fit on a 2000 model 3100?

    just the block? you'll run into the same problems as those swapping from a 3.1 to a 3x00. bosses are different for the front mount. you'll also run into problems using the 3x00 main caps and oil pan.

          it won't run nicely with out the cam sensor. It affects fueling and will rough bad at certain points.

              Tell him to make sure ge gets a 3100 block. They are alot better in many respects. The best being priority main feed oiling and then the roller lifters.
