That engine has a ROLLER CAM AND ROLLER LIFTERS
It has hydraulic roller lifters.
No to the roller lifters in the 2.8 Ford V6. The 2.8 as well as the 2.9 has regular flat tappet lifters and regular rocker arms.
YES it does and it is a roller cam and hydraulic lifters.
Yes they are.
YES, they sure will.
NO. The 86 is not a roller block.
Probably not, unless they were added later. It should have roller lifters however.
No it does not. Chevy did not start using a roller cam until late 1995.
They all had hydraulic lifters. To determine if it has roller lifters, you'd probably need to take off the intake manifold and have a look.
hydraulic lifter non roller
yes like 350 engine
No, first generation 3.1 does not, second generation does.
Not if you did it right the first time.
If you have a 2001 or newer engine, it comes with roller lifters and roller rockers from the factory.
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
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.
The 1990 will take flat hydraulic.
low oil pressure or the seal on the roller tappet is old and it takes the roller tappet a minute to pressurize again.
Must be fairly recently, because I haven't seen that in a factory-built sbc. They've been using roller lifters since '87.
can the valves be adjusted on a 1998 454 7.4 vortex with the roller lifters
Look in the valley between the lifter bores. If there are two bosses with small threaded holes, then it is a roller block. These holes are for the bolts that hold the spider bracket that holds the roller lifter brackets in place. You can buy roller retrofit lifters to use in a non-roller block.
Yes you can as long as the cam that you are calling original is a roller cam.If it is just inspect the lobes on the camshaft real good and close.
