I have to change the camshaft in a friend's '94 Z28 with a LT-1 motor. Someone told me I could just remove the valve covers, rockers and pushrods, remove the front of the engine and pull the cam without removing the lifters (???) and they would stay there. If that is true, it would save me a lot of time since about half the intake manifold is under the windshield and is a PITA to remove but I can hardly believe this...anyone heard about that ?

I've heard of that with certain engines and certain aftermarket lifters, but I don't believe the LT1 is one of them. I have one in the garage I'm putting together, and there's nothing to hold the lifters up once the cam is removed.

I think you can do it with the engine on a stand, and rotate it 180*. Then the roller lifter retainer device keeps the lifters from falling out of their bores. Never heard of an "in car" cam change without removing lifters.

I can do a cam change in my 355 due to the mechanical roller lifters I have. But its no LT-1. Did you try posting on a real 4th gen site where people work on these engines daily? that might help.

I talked to a guy at Anderson & he said he didn't know of anyone who had used them on a Chevy, but that it might work.

Nice idea, but wouldn't work on an LT1 due to the way they retain the lifters. Looks like it would work with aftermarket lifters that don't use a bolted in "spider" to hold the lifters in place.
