I have flown several WWII era fighters. Nothing sounds like a Packard-Merlin engine. They are very distinctive in nature.

Umm, Keith, you can not make a statement like that, and NOT expand on it!! There are a very select few who can say that! I noticed the Air Force wings, and the aviation quote, but never asked you about it.

I'm a big vintage aviation buff. I've flown as a passenger on the Sentimental Journey and Diamond Lil (B-17 and B-24 respectively) and an early 30's open cockpit Waco. I would absolutely JUMP at the chance to fly in a fighter, but most are single seaters and I don't know of any others that actually give rides. I would love to hear more about the planes you've flown!

I have always just used  regular NPT taps, which fit the lifter feed passages perfectly, a bit tight for the larger galley plugs, but no problems. That said, if you are going to tap all the oil galleys for pipe plugs, you are not ready to start assembly after cutting the pipe threads. I always do any drilling, grinding or tapping of the block, before installing the cam bearings , and do a final thorough jet spray wash, and blowing out all the oil passages, and every nook and cranny before even thinking about installing the cam bearings and beginning assembly.
