Yeah? Did you not know the lifters were the same or are you excited about used lifters?

[ForcedFirebird]

Sappy, will they fit a LHO (RWD 3.1, 1990)? Someone on another site is trying to retro-fit a roller cam on an F-body (haven't heard lately).

[SappySE107]

I don't know for sure so I won't even guess. I don't have a flat tappet setup here to check. I know curtis went roller but that was solid so they aren't the same lifter.

[ForcedFirebird]

I'll get back when I hear something then...

Ben, you think 200,000 mile 3100 could benefit from these lower mileage lifters? My car runs real good, but always looking for cheap refreshers.

[SappySE107]

If your car runs good, your lifters are probably fine. However, 200k is quite a few miles. Price is right but you gotta tear the engine down to swap them. I don't know that I would do that right now.

[IsaacHayes]

Do the heads have to come off to get the lifters out? I just thought about that. I still gotta swap my intake manifolds, but I'm not touching the heads..

[gectek]

no, for lifters just the uim, lim, and valve covers and rocker arms/push rods. then the lifter plate and they will pull right out

[IsaacHayes]

Thanks guys!

i know that back in the day i did place a 3100 roller lifter into a flat tappet 2.8 block. so the bore size for the lifter is the same but it may end there.

[bszopi]

They will fit in a non-roller block, but they you need to figure out how to keep them in place, since the non-roller blocks don't have the provisions for the anti-rotation bars.

[ForcedFirebird]

Not only that, but there is a difference in the oil passages that if used on a non-roller cam motor, they would be starved for oil. A guy on TGO is looking for a way to use them in a f-body and I believe he has solved the rotation problem, but not the oiling.

[gectek]

cant you chamfer the bore with a bore chamfer kit, i thought i saw one from comp cams, that is what would give some needed lube
