I bought a '82 k-10 w/6.2, 3 spd OD tranny and I don't know what the gear ratio is on the axles. I got this truck about a year ago and use it to pull my 5th wheel. I determined that it is a C or light duty since it has the EGR valve. I bought a '85 intake for a heavy duty. There are only a few differences I can see between the manifolds. I have a couple of questions about changing the intake.
1. Has anybody kept the 2 fuel filter set up and where did you mount the secondary filter since there isn't a mount on the back of the newer intake?
2. Does it matter which gaskets I use (HD or LD) since the EGR ports on the heads will be blocked by the intake?
any pointers on making this an easy trade off?
Also I saw on another thread somebody mentioned the 599 engine and the 600 engine. What is the difference between the two?
Thanks for the info. I am sure I will post a lot more questions as I go about pumping this truck up.
