Me and my buddies were talking about how long my NA build will last and we came to the conclusion that it wont last more than 20,000 miles. Now ill prob end up spending over 10gs on this build so I would like some opinions on this subject.
Also will I have to be driving it all in the revs to keep it from running like ****? Mods include Jun cams and valve train, high compression pistons, rods, sleeves, port and polish head, etc.. basicly fully built NA motor So how long will it last?

 

if its built right and driven right, which does not necessarily mean keeping it under 3krpms all the time, the motor will last as long as you want it to.

 

The motor can last almost as long as stock if it is not abused.

 

Well it will be abused thats my purpose of building!

That's stupid.

It'll last a long time as long as you take proper care of it. As in, don't redline it when its cold, change oil regularly, etc.

exactly.. abusing it doesnt mean running it hard. because thats the point of building it.. you want to use every ounce of power you can make. just keep up on maintenance. if something does break fix it right away.
