next best thing is to find a 1985 to 88 ranger 2.3 block , it has the drainback there , just pluged , these can be had cheep , great if your still driving the car and can do the swap when the time comes , (less chance of small parts getting lost) also the intake manifold can be used for the turbo , you just have to change the injectors out for the larger ones , snagg the EFI wiring out the ranger also , you just have to add a few extra wires forthe mass air sensor , the rest like the distribtor , the head is the same , the next plus is the block has the one peice rear main seal , not like the two piece seal you have now ,
