crate motor?
I was told I bought a 1996 crate motor with aluminum heads and only 4000miles on it. It has 340hp but a casting number is crushed I cant make it out.All I see is E7** and ive only put 19 miles on it and the lifters are chatteren so I take off the intake and I see plastic lifter retainers witch are stock not crate motor also the oil is black with only 17miles not burned I changed the oil and filter still lifters are noisy both sides now.Also the heads are non adjustable rocker arms more indication of stock,mine main question dose anyone know what years put plastic lifter reatainer ,somethan tells me its a 1993 stock motor with no cam cheap vaulve train and 240hp if I'm lucky,any info will be helpful no crate motor should have non adjustable rocker arms I wouldn't think right?

Are you running this motor with a carb or EFI?
What oil did you use?
Never seen plastic roller retainers can you post a pic?
Did you have to install pushrods or was the motor complete?
Where did you see the casting number.. on the side of the block?
Most Ford heads have non adjustable pedestal mount rocker arms but a HP crate motor would not have the same heads a production motor got.
The clattering valvetrain noise you have is very bad especially of this is a roller motor, if I were you I'd check oil pressure and then ignition timing to make sure it's not way too advanced. That brings up another question, what distributor are you using and how did you set timing?

I have a 302,MSD box and distributor,i was told it was EFI but now has an eldabrook 600 carb and worrior intake.It came with the alum svo heads casting num f32m-6049-x302 and vaulve train installed, non adjustable rocker arms.I used 5w30 oil,FL1A motorcraft oil filter,i tried changing the oil and filter but still makes the tapping noise , first it was just one side now its both sides not crazy bad, but I aint driven it ticken ,HO firing order,push rods and all where installed.casting num I think by where the starter was I will post pic soon of plastic lifter retainers,oil pressure id way (good).I bought some stuff called motor flush its a quart you add and let the motor run 5 min, ima do that and change the oil and filter one more time that way if theres a lot of dust or debrie that brakes lose itll go into the old lifters,i had another 302 with a f303 cam and lifters I was told the lifters should be the same I hope.

Yes all these motors use the exact same roller lifters, higher lift cams do produce a sewing machine type of mechanical noise when the engine is running they aren't totally silent like a production motor.
You may have to dig into your motor to figure out exactly what is wrong, if the PO did something stupid like install a flat tappet cam with the roller lifters or mistakenly installed a retrofit roller cam which is ground on a smaller base circle then the pushrods will be too short and the valvetrain very noisy.
