How to Install a Comp Cam in a 5.3L LM7 Part 1

I show you the basics of installing a cam in a 5.3L (LS1 type engine). The cam I install is a new Comp Cam part #54-455-11 with 215/223 Duration and .604/.610 Lift on a 112 LSA.
To go along with the install I put in new 7.4" Hardened Chomoley Pushrods and Comp 918 Valve Spring good for .625 lift.

@subaru733 Thanks!

Thanks for a great install video. Im looking at going with the same setup as you. Any issues after it was together? Also do you know what the part # is off the push rods? If not what would you recommend?

@cdsnds31 No issues after it was together. I eventually swapped to a 6.0L but the cammed 5.3 was great. Any hardened pushrods should work probably need 7.4 length.

Awesome sound track...you say magnet weird. I have a 4.8 that I'd like to put a bigger cam in. I heard that you can run some kind of dowl rod through the block to keep those lifters in place? Is that at all possible?And are the springs and push rods necessary with a bigger cam?

@adamdta1990 Thanks, I'm not sure if its possible I've never done it that way I once heard the truck variation of LS engine don't have those holes drilled. Springs and pushrods are absolutely necessary with a bigger cam.

I drive s 85 Honda CRX, I want to know if I get a can of starter fluid and run a long small hose of the nausle of the can and run it into the air cleaner right above the carb, will it add any power? Iv done some testing with a riding lawnmower, catastrophic fail. Any ways any tips help.

Whats the trick to getting the lifters to stay up? I'm getting ready to put a cam in my 93 5.0 Mustang and if i could leave the lifters in that would save a lot of time and work.
