How do you adjust lifters on a overhead cam?
they have no lifters
Can you use a 350 cam in a 305 engine with its original lifters?
Yes, but you must keep the lifters with the cam they were originally used with.
1997 Chevy 305 have hydrilc lifters?
YES it does and it is a roller cam and hydraulic lifters.
What type of lifters are in 1998 vortex 350?
That engine has a ROLLER CAM AND ROLLER LIFTERS
Do you need new hydraulic roller lifters if you have a new cam?
Officially you should change lifters anytime you change the cam. In real world use; unless the roller lifters have obvious, visual damage, missing pins, wear on surface of the roller, then it is not normally going to be a problem. In the case of flat lifters, you should change them. The cam of flat tappet (regular) lifters, have a slight bevel to the surface of the cam. When the cam and lifter are in operation - this causes the lifters to rotate in their bore. After/during break-in, there is some wear on both surfaces and they end up with a pattern which is unique for each bore and and each cam/lifter combination. If you change either the order of the lifters on the original cam they meshed with, or install a new cam or new lifters - there is a very real chance of accelerated wear leading to failure of cam and lifter. What is worse - the resulting debris can follow the oil and ruin bearing surfaces throughout the engine. Your money, your choice.
What does it mean when one of my lifters is barely moving in my 1977 Chevy pickup 350?
It means the lobe is worn off of the CAM SHAFT. Need to replace cam and lifters.
Does a 1975 350 engine have mechanical flat tappet lifters?
typically no it should be hydraulic lifters unless someone has changed the cam and lifters in the engine.
How do you find the cam grind on a Chevy 350 There are no markings at the timing gear?

Can you mix a hydrulic cam with solid lifters in Chevy 350?
no
Do crate engines come with a cam heads and lifters?
Yes.
How do I replace 2.9 L lifters?
If the lifters are noisy, usually replacing lifters alone won't fix it. 2.9's dump oil internally, as the cam bearings wear. excessive oil is lost between the cam journal, and the cam bearing. Not enough oil actually reaches the top end. Additionally, you have to remove the cylinder heads, to get the lifters out of their bores. That's a lot of work for a repair that may or may not work. You may as well pull the engine, replace the cam bearings and cam, and lifters. Since you've gone that far, you may as well install a Melling high volume oil pump.
How do you replace the hydraulic lifters in a 1973 to 76 Chevy 350 engine?
It's not recommended to change just the lifters. The cam and lifters should be replaced together. To get at the lifters, you can remove the rocker covers and intake manifold, loosen the rockers enough to get the pushrods out, then pull out the lifters.
