1977 ford mustard cobra 305 4 bbl?

I was thinking about buying a 1977 mustang cobra and I was wondering if anyone knew how much horsepower it has and if you suggest trying to make it better and how to add horse power thank you I'm not very good with cars

Not much from the factory but it is an easy buildup for alot of power. 302=5.0 the 77 was the mustang II wich was a small car with alot of potential

The stock 302 was 132 horsepower, but this was due to it being a low-revving engine with strong torque at the low end and and dropping sharp as the horsepower peaked at below 4000 RPM. So you can't really compare the low RPM engines of the 1970's to modern high revving engines that came along in the 1990's.

The best thing to start with is to get that engine running back to original, which would do burnouts all day long due to the torque. By now that means a carburetor rebuilt by someone who knows carburetors. And a good tune-up along with likely a new timing chain by now.

Nice thing about that engine in that small car is that there are loads of goodies for a classic 302. And you don't really need a lot to move that small car - or the Fox body that came along in 1979 when the 2 barrel 302 ran pretty darned good.

The bottom fell out of the muscle car market in like 1974 when Uncle Sam made un-leaded gasoling standard. So the '77 was a low performance car but fairly easy to work on.
