there is no such thing as a 77 nova ss
last year was 76 that had a 350
I have a 77 Impala with the 5.7 4BL carb and stock it puts out about 260 hp
No, not the same body style.
Is that an answer or a question? For the 77 Nova any 262-400 will be a direct swap. Big blocks can be done if you use the 396 mounts from the '68-'72 Novas. If you have an L6, swap motor mounts and a small V8 should drop right in. Of course, you'll need to modify your exhaust and a few other things. Is this what you were looking for?
The distance is roughly 77 kilometres http://southwestnova.info

V-8 or straight 6?
To remove the motor mounts on a 1977-1979 Chevrolet Nova, start by securely supporting the engine with a hoist or jack. Disconnect the battery and remove any components obstructing access to the mounts, such as the air intake or exhaust. Unbolt the motor mounts from the engine block and the chassis, then carefully lift the engine slightly to free the mounts. Ensure to replace any worn or damaged mounts when reinstalling.
If you have a welder to weld in new motor mounts and use a buick, olds or caddy transmission and make a new crossmember mount for the tranny and have a new driveshaft made you can make it work.
Go to a fashion show, knock on the door of the model Stevens and give him 77 kisses.
Take it easy for about 500 miles. Change the oil/filter at that time and then you can drive normally.
77
This depends alot on what engine/tranny combination you have and how you drive it. When my '77 had the stock 305 2bbl / TH350 / 2.56 and I was in high school it got around 14mpg average. As the rings started failing, it got closer to 10. Not long after that point it threw a rod.
