re:
big engines on their cars
From my youth up to ~ 15 years ago, I specialized in 7 liter+ engines. Actually, I'm glad to be away from them now. I have read that Tata is supposed to come out with a turbocharged diesel Nano, and that sounds pretty interesting to me.
and v twins on their bikes
I do have a 1956 Harley Davidson; it is a flathead (that old-time configuration I have an affinity for), but I've always been jealous of the Brits over those wonderful Vincent V twins. Lovely machines!

I used to drive over to Ft Worth to visit them, but now there is a new store branch that's opened up about 15 miles from the house. I've been through the new store and they don't have that old time sort of surplus that was fun, and it doesn't have all the "junk" that the old store had. Maybe the old store doesn't carry that stuff anymore, either.
Another surplus website i have been looking at is jgsales.com
J&G has been around for awhile and I've been in there a couple of times, years ago. However I never bought anything from them. They are a good source of guns and ammo, however.
I've long been kicking around getting one or more of the old Russian/Soviet Nagant revolvers. I'd like to, but really don't need to add another caliber and reloading project at the moment. Still, for reloading and casting bullets, Nagants would be a fun choice!
