How Many Miles??
 

Just out of curiousity.. but how many miles you all clock on your original engines before you had to replace, rebuild,.. or still run?

Mine had 400K, on the original 305.. still ran good too,... apparently was too worn to burn clean anymore for emmisions...(burning too much oil)

replaced with a 350

I'm about 1/2 way, at 187,000.

As far as I know, the air cleaner (base) has never been off.

(ie, original gaskets, intake never off, etc).

Come to think of it... I know the transmission fluid and filter have only been changed once, and that's when my dad had the new engine put in... dont think the rear-end has been messed with either...since we got the truck back in 89

wonder how many miles one can put on these things before something goes?

I know the truck hasn't been abused.. (Hot-rodded around and such).. maybe that helps?
