When did 5.0 roller engines start?
I've got a 5.0 EFI coming from a salvage yard for my 1994 F150. Its a truck engine according to them. I didnt ask what year it was from, according to them it is the engine for a 1994 f150. I didnt ask what exact year truck it was from. Now I'm wondering what year the engine is and if its a roller motor. What year did the 5.0 truck engines start as roller motors?

The 5.0 truck motor got a base roller cam in '92.. and the both the 5.0 and 5.8 got the F4TE roller cam in '94. You'll want to swap out the cam if you get a motor with the base roller cam.. it's really sad compared to the F4TE cam and strangles the motor.

I will tell you anouther thing to look for, the knock sensor hole. Trucks and vans have this provision. All others did not. The hole is located right behind the intake manifold. it is a blind hole,which means is does not go all the way though the block. It stands stright up. If the block in question does not have this hole you will not be able to hook your knock sensor up causing your check engine light to stay lite. Also, you cant drill and tape this hole,there is not enough material, the block will crack, the hole is pipe threaded.
One way to tell if its a roller block is to look at the lifter valley, it should have the two small,taped holes, for the lifter spider. To some it up, look for the hole, look to see if it has the provision for the spider.
I have a 92 that needed a motor, I started with a bare block, mine was cracked. I did not know about the knock sensor issue,but I do now, almost used a GT block. I hope this helps you out.

The most accurate method to determine the date of the engine is to note the Casting number and date code from the cylinder block (cast onto the block above the starter motor). If you need help to decipher them, just post them in this thread.

The roller block casting numbers are: E7TE, E6SE, F1TE. Might be more too. As mentioned before, the roller cams went into the trucks & vans in 1992 model year, before that, they had a roller block (starting in 1986) with a flat tappet cam. If you now have a 94 truck, you'll need to make sure the replacement engine has the 94-up F4TE cam.

I'll check as soon as I get it, I'll post the number back on here to see. I plan to rebuild this engine anyway so the cam will be replaced.
If its roller block I shouldnt have an issue, right?

Some of the roller blocked truck/van 5.0's that had flat tappet cams didn't have the lifter valley retainer bolt bosses drilled and tapped, some even didn't have the bosses fully cast, I have one of these, the bosses are there, but not fully formed. The last two blocks like this I've aquired, one had the bosses drilled and tapped (but plugged with carbon gunk), the other had the "half-cast" bosses. One was an 88 block, the other an 89. Ditto on the knock sensor hole too, mentioned by 60oneton, although I think you can drill and tap this on any of the blocks.

OK all, I'm back with numbers. Please tell me what you can decipher from this. I need to know quickly. If this is not a roller motor I will be doing my best to return it.
F1SEBB12
also there is a second number - 4029

They came off the block in the general vicinity of where the starter would be (if it had a bell housing). When I run these numbers it shows from a 1991 T-Bird! I would like to think Planethax is right but there is no other indication this is a Cobra engine. Help! Do I keep it or send it back?? Paul?

Back to top, need some help from those of you in the know.
Is this a roller motor, truck or car?
Suitable for my 94F150?
Is the lack of the anti-knock sensor a big deal if its a roller motor?
Just need to know what you all think, I should be able to return it if needed.
Thanks
Craig
