Yes it is another which cam thread and I have scoured the inter webs for information on what others have done. Not many people in the truck world have shared their stories, shocking I know. The tool box sticky I read a few times and it has suggested a few and another thread had different heads with their cam selection. I want to know what others, if they’ve even done so, have put in their stock L31 crate motors.
I have 256k miles, to my knowledge, on my truck currently and I can feel a rebuild coming on. General consensus is it is cheaper to buy a crate engine over rebuild. I am purchasing this :http://www.jegs.com/i/Chevrolet-Performance/809/12530283/10002/-1, and both jegs and summit have good reviews. There are 2 from summit that had issues as soon as they first fired but I’m not as concerned about that as I am on changing the cam to void the warranty. I figure there’s a lot of red tape to deal with if a warranty issue should arise that it goes out the window.
Now while the crate waits to go in why not install a better cam.(springs too, if the need should arise) The only helpful information I could find were in the tool box sticky and there is only 1 cam for stock springs and 2 for I am assuming the beehive springs. Also from what I have read a minimum of 112° LSA is required to keep the computer from having a fit. Can anyone shed some light on this?
Along with the crate engine there will be other upgrades as well. Such as a set of long tube headers(unsure of deleting EGR or not) 2.5 dual pipes with Magnaflows, transmission overhaul and a Black Bear Tune. I am not building a drag, race or mud truck. I just want to drive it and do some towing on the farm. Figured while I am going through the effort to install a new engine why not do some minor enhancements while I am there. The truck is still stock with tires, gears(3:73) and transmission(4l60e).
I am wide open to options and suggestions. I greatly appreciate any and all input.
