6.5 guy... I still build them every day... I'm an old school mechanic of 35 years... have a 6.5 in my el camino and one in my 64 c10. But needed a good reliable everyday truck to tow with occasionally. So, I bought a 07 2500HD classic. Has a K&N cold air on it. Looks like stock exhaust... other than that, I haven't yet dug into it to see what has been done to it.
Going to have some questions...
