When does one decide a case has to be align bored? I have a GC case that I am getting ready to take to the shop to check for register collapse but have no idea what the criteria might be to consider align boring.
Thanks in advance! |

Rimco in Southern California does a great job with type-IV cases. http://www.rimcovw.com
I usually just mail them down there have the case align-bored, shuffle pinned, drilled and tapped, and have them send it back with bearings to match the case. |

Since a correct and good case is crucial to ALL builds (budget or racer) I am sending mine off to Len at Hoffman Automotive (HAM Inc). No one could do a better job than they could - and I am a newbie at Type 4 engine builds.
Mechanically I can put it together - afterall I have watched Jake's Type 4 video like a thousand times - but if you start with junk you will end up with junk! I have verified that the case is a virgin (never align bored) and I have a new set of Mahle STD x STD main bearings. Thanks to all for your help on this. Details on build issues as they arrive! Cheers! |
