What kind of engines?Trivia challenge

Betcha can't identify all 3 of these rarely-seen engines I saw at recent shows.
I'll reveal the answer later.
If you get them all right, you get one "attaboy".

(hint: they are all in the cars they originally came from the factory in, and they're all American made.

 

third one is a Studebaker

 

First one is a Crosley. Is second one a Cord ?

 

1. Crosley
2. 1917-18 Chevrolet V8
3. supercharged Kaiser 226 6 cylinder--must be a Kaiser Manhatten?

 

1st engine crosley
2nd engine got me
3rd engine supercharged kaiser manhattan

 

You guys are amazing! Hank37 got the Crosley right within 5 minutes of my post. Within 8 minutes, Heathen got all three right!
Attaboy, Heathen. How'd you know them all? I never woulda got'em right if I hadn't seen the cars. Cord and Studebaker were'nt bad guesses either.
Thanks everybody.

 

It comes from years of staring at everything I could find that dealt with old cars.

 

Nice! I got the staring at it part down. It's the retaining that info that's a bitch!

 

OK, put on your thinking caps. Here's a difficult one.
Hint: it's from an American concept car, 16 valves, 335 h.p.

 

1961 Buick XP-300 experimental engine

 

Virgil got it, but forget the picture. The specs are for a 1968 Plymouth Roadrunner. It had a four-speed manual transmission and a 383-cubic-inch V8, 16-valve engine. With 335 gross horsepower.

What do I win?
​

 

Yup. Virgil got it. I'm impressed.
Not yer ol man's Buick, it was from Buick's 1951 XP300....an aluminum blown hemi.
You guys are too smart for me.

 

Why would anyone hang that ugly alternator on that supercharged Kaiser?

 

Are the exhaust rockers mounted longitudinally? Look at that wicked angle on the intake p/rod to rocker... cool schematic.
