Re: 1971 C-10 knocking sound and not reving past 3000 RPM
I was finally able to pull the cam out of the motor only to find that several of the exhaust camshaft lobes were going flat if not there already. It is so bad that the whole motor would need to be rebuilt. That's where I have a question, my dad is currently building a 62 C-10 with a 6.0 liter LQ4 that he got for around $1000. I have been looking at 5.3 liters and it looks like they are around $600. I know it would be cheaper to rebuild my engine myself and have some of the motor machined than having to buy lots of different miscellaneous parts for the 5.3 but I was wondering what you guys thought of going the 5.3 route for increased reliability and better gas milage. Any input is very much appreciated as I have done a lot of research on this but still wasn't sure the correct route to go given my situation. Thanks
