No way would a 292 fit. My 250 barely fits and it's a couple inches shorter.
maybe a side draft set up might fit but I doubt it. The problem is one of height. The 292 is 1.75" taller.
Sure they fit.
Look at how tall your engine mounts are.
They fit in a friends 65 Nova, Chevelles, El-Caminos etc.
There are different engine mounts to let the engine sit lower. Make your own also.
Easy peezy.
