I'm close to cologne/Düsseldorf area roughly 400ft above sea level. We will put the engine first in a stand for breaking in. I will shoot with the 0.039 head gasket and see what temperatures say on the stand. Car is a close 4000lbs 64 b Body with 2.76 rear axle and 2000 stall speed converter. I don't care about 60 feet times or so. My goal is max acceleration in 3rd gear on the highway from 3000 RPM to max speed.
