Its not a junk engine.
Im assuming your saying you built the engine up.
(cant tell, bad english or lots of typos).

But basically, a 351C is alright except its heads are too big. This makes it a poor engine for streetability.
A 351C makes a better race engine, because it needs to be revved fast and hard all the time to run properly, because of its heads.
Thats why the engine didnt last long as a street engine.

The guy that made the "bitten by the snake" video had bought a cobra with a 351C. At the end, he says he wished he bought a cobra with a 351W instead, because its a more streetable engine.
