tech has sure changed. lol

 

But what was the TORQUE number?

 

Back in the day my parents had a 1977 Caddy coupe de ville with the 500 cu in engine...if that car made 150hp ..I would be surprised...one of the slowest cars I have ever driven

 

and you think roller rockers were made when...…..try back in the 20's. my machine does a lot of old engines. quite a sight seeing how they did stuff.
amazing what they did 100yrs ago.

 

I like that car !!
I think in 1919 the 38 HP rating was a threshold (under/over) for tax purposes.

 

"77 was a bad year for HP
