The Quicktime housings are done on CNC equipment, whereas the old Lakewood stuff seemed to be done with a drill jig. I have always had to align a Lakewood. I have never had to align a Quicktime.

I would encourage you not to use the offset dowel pin alignment procedure. It is imprecise, does not repeat with bell housing removal and replacement (w/o readjustment), and changes as you tighten the bell housing attaching bolts. Did I mention it is a PITA to do?

Almost 20 years ago, I did a write-up on how to align the bell housings to the blocks. It covered both the why and also the how-to questions. If you are interested, it's still on Club Cobra; click here => Bellhousing Alignment

The technique I describe will consistently allow you to bring the TIR to 0.001" or less" and it will repeat, with a zero fiddle factor, for as long as you are alive!!

To use a slide hammer you need to drill a hole in the dowell center, imposible with a hardened dowell.
