My truck never had the insulation piece under the hood I got one now, should I put it in?

Yes, it dampens some of the engine noise and helps protect the hood's paint from engine heat.

Won't the insulation make it hotter under the hood by trapping heat?

Bad idea for a truck with that weight and 4wd. You'll have to spin it up to get any power, and it'll be a dog down low. If you still want to run it, you'll need springs and retainers for the lift, a higher stall converter, headers and full exhaust would be preferred, and a custom tune.

Thanks can you recommend a good cam for my truck it has 410 gears and at 60mph I'm pushing 2000 rpms i have full exhaust but stock manifolds and I am looking into the 4011 pcm

The 180235-14 cam from Howard's would be a good choice. It's mild enough to use the stock converter and manifolds, but will require springs and retainers for the lift. The 0411 is a good idea regardless.

That will work what are the best springs and retainers to use to raise the lift ?
