You need a bigger tailpipe!!! (on the bus) Dan Martin <danandkatrinamartin@xxxxxxx> wrote: There seems to be very little chatter lately, so I will try to start a conversation. During the investigation of a oil leak on a type 1 it was discovered that the engine had 94 mm piston and cylinders installed. Upon further investigation a stock riveted cam was found. My topic is the reasoning behind building such a motor. From what I understand, and I could be wrong, the case has to be machined for the 94 mm P&C to be installed. I just don't understand why one would build one configured this way. Am I missing something? And to keep the conversation offensive to everyone ( never discuss religion, politics or bore and stroke with strangers ) what would you build, or have built or already have for the perfect bus motor? I will even go out on a limb and tell everyone that I had a local builder build me a 1600 cc engine with a new Auto Lina aluminum case, stock stroke counterweighted crank, Engle 110 cam and stock size valve single port heads. I run a 34 pict 3 carb on a adapter plate on a stock type 3 auto stick single port intake with large vacuum port. ( for the brake booster ) I use a stock exhaust system with heater boxes. I have a stock dog house cooler without flaps. I installed a Berg 1.5 quart sump, and a Berg dip stick thingy to keep an eye on the oil temp. Discuss............
