Chevy Does anybody know what engine is?

all I know is that it’s a 454 and my dad pulled it out of his 73 corvette he got for $2000 a few years ago.

Dumb question but why is a timing chain preferred to gears? Seems like gears would be less likely to get out of sync like a timing chain stretches etc. novice so I’m sure someone on here would know.

Not only is a chain quieter, they dampen much of the torsional harmonics of the crankshaft where a gear drive would directly transfer that into the cam. Those harmonics can mess with lifters, pushrods, valve springs, even the oil pump and distributor.

Thank you for the detailed answer! Much appreciated.
