cam swap question

I'm replacing my cam in my ls3. I've never done this on a v-8 before (only l4 with ohc). My question his what is preventing the lifters from falling when I'll remove the cam?
Thanks

nothing unless you either pull the heads or put dowel pins in

Go to Home Depot or Lowes or whatever hardware store is near you and buy 2 long wooden dowels to hold them up.

Get 3/16 in. I used 5/16 and one side went in fine, the other I had to jam in. I used metal, some use wood. Wood might go in easier but may end up shaving off.

Basically remove rockers and pushrods timing chain. Spin cam several times and lifters will remain off cam. Pull out cam and replace. Do not wait too long after old cam removal. Have new cam ready to slide in. Good Luck

that way is fairly risky.... a lifter CAN drop... and if it does you have to pull the heads.... dowel rods are cheap and great insurance

I used 16 pen magnets... extended them.. pulled the pushrods and inserted those, you will hear a click... thats the magnet grabbing the lifter. It will only come up about an 1/8th of an inch if that depending on the postion of the individual lifter.

Go to LS1howto.com and they have a step by step guide on how to do this with several options for certain things.

Home Depot/Lowes...

36" of 5/16 Steel rod..

Cut it in half....

Spin the cam to get the lifters to "hold up" in the retainer...

Insert homemade Lifter Holders...

Lifter Keepers...

Life is good.

Best $4.88 you'll spend anywhere.

My Tech Help...
