These numbers come from the factory shop manual. Evidently, it's when the 1756 was new because it doesn't have much info on it.

so if im reading this right. the 1608 has more horsepower and torque then the 1800? just higher up in the revs. and since i have a 1608 in the garage, might as well go that way. thanx denise. early spiders rule....

Dang, I typed that in neat columns but I guess it didn't stay that way.
Yep, that's how I read it too but I don't know when the smog pump and such enters the picture.

I would have to agree that bigger is better, the 1800 is a free revving engine just like the 1600, plus you can use any 1575, 1800, 2l cylinder heads. Any modest improvements in the engines, CR, cams, carbs, ect. will yield you bigger gains in HP and Torque over the 1600. But that being said, if you got a running 1600, use it or sell it.

That's better Alvon. No comp ratio for the 1756 in my book.
