I checked out a couple of mild cams on comp cams website last night. They all said that you have to change the rocker arms to an adjustable style? Does anyone make a cam that is just a stock replacedment with no other mods required? This truck is my daily driver so I don't need to go crazy but I could really use some extra towing power for the mountain passes we have around here. I'll be interested to see how much a straight through muffler, cat delete, and 3" tail pipe gain me.

After rebuilding my engine with a cam i've realized that a cam upgrade is a can of worms.
I would suggest checking your compression and only go down the cam road if you need new head gaskets or a fresh top end. If not, I would leave the cam in and start looking for a supercharger on ebay, that is the most efficient way of making more power.
If you decide to replace the cam, you'll need the adjustable rocker setup, which isn't difficult to install nor expensive, though I wasn't able to use the poly locks as suggested, i guess the ones i got were too short, but there is a risk of the taller ones of clearing the valve covers.
You may also need new valve springs depending on cam.
And a tune, I've found, is not as easy or cheap as you would think


Did you put in aftermarket pushrods or lifters?
Could be one of them are blocked, or a cam bearing isn't lined up with the oil hole.
Or as Tom mentioned silicon blocking an oil passage at the rear main, though you'd have like no oil pressure anywhere if that were the case.

New comp cam and lifters new longer pushrods to match new aluminum heads. New roller tip rocker arms. Everything in the entire engine is new except the block

The guy who assembled it has assembled many engines for me without any trouble I'm sure he cleaned the block thoroughly
