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.
YES it does and it is a roller cam and hydraulic lifters.
That engine has a ROLLER CAM AND ROLLER LIFTERS
In most cases either will work. but you know how you are building your engine so you should know better then I do whats best. NO!!! if you have the serial # of the cam get ahold of comp cams and they can tell you if it is a roller or flat tappit cam they are totaly diffrent cams and WILL NOT INTERCHANGE LIFTERS
The 92 did not have a roller cam in it.
It is a hydraulic camshaft, Not a roller cam. Chevy did not start using roller cams until late 1995
hydraulic roller cam.
Yes, you will need an E-curve cam to have the correct profile for EFI. Edelbrock, Comp Cams and other aftermarket manufactures have cams for such swaps, or you can find a cam from an 88-newer 5.0L/302 that has EFI from the factory, in doing this you will also need to change the lifters in your engine as stock 88-up engines feature hydraulic roller lifters, any flat tappet lifters will wipe these cams so its best to do the swap.
typically no it should be hydraulic lifters unless someone has changed the cam and lifters in the engine.
No it does not. Chevy did not start using a roller cam until late 1995.
no valve adjustment. hydraulic lifters (cam followers).
The valves on the twin cam are non-adjustable, they use hydraulic lifters.
It don't have a roller cam That's for sure.
