Today was going to be the day we fire up the blown 354 Hemi. Spun the oil pump up to pressure all ok. When we tried to install the intermediate shaft it didn’t want to go all the way in.Tried to turn the engine with a socket and bam chipped a tooth on the gear. Upon closer examination we noticed that one of the plugs threaded into the block under the distributor was contacting the gear. We can fix the plug issue but will need a new intermediate gear. People have told me to fit the intermediate shaft when the engine is on the stand because it’s easier that’s ok but then you can’t spin the oil pump up with a drill to get pressure?
