73 CIS Block
Just use the 73T block.At 140 Horse it should not need any work.The 911/83 has probably been beat like a stepchild.The mag cases fatigue and crack as well like a 935 or 962.Most of the early mag cases get slightly oval in the line bore just get a clean line hone to be true.There are no case stud issues as they were not stressed and do not need case savers.Good studs and a Rawknees size oil cooler up front to keep it cool.$3-4,000 less to use that block.Just call my buddy Peter.Oh,he just got a.new knee.Ciao Fred

Fred, I'm gonna build it myself. Ive never built a 911 engine before, just trannies. I've done dozens of Subaru engine, but never an air cooled. If i had a buyer for the case i might use another. Ive got half a dozen engines here from 2.2 to 3.2.
