I've been looking around for a possible replacement for the stuck 272 thats in my '58 SWB and I came across a Y that was supposed to have come out of a school bus. It was in an old shed and I didn't have my camera with me so I dont have any pics to help with the I.D. Anyway, it has the wide holley pattern as well as the ramshorn exhaust but the front of the motor looks different then other y blocks, like it had a taller waterpump casting or something else sticking up in the front. It also had a power steering reservior and the tubing wrapped around the reservior to act as a cooler I guess. I pulled the heads and couldn't find any casting numbers. Any help on what this motor might be  would be appreciated. I might be able to get some pics at a later date.

If the engine looks similar to this one, then it could be a 302 or 332 LYB engine.  These engines were common in the larger trucks of this period.

The valve covers, heat shields and exhaust manifolds are the same. On the water pump, at the two top bolts there seemed to be an additional casting or some type of a bracket attached there. Would this be a good motor for parts, ie. heavy duty stuff like cranks, rods, ect.?

If it looks mostly like the one in Ted's picture, then it will not be a good parts motor for a Ford Y-Block. If you want to get into the Lincolns, then it can be a good one.

That sounds like the bracket used on truck engines to move the fan higher on the radiator. Is it slotted? Chuck in NH

Looking for McCullouch VS57 brackets and parts. Also looking for 28 Chrysler series 72 parts. And early Hemi parts.

the casting numbers will be over the oil filter or back by dist,.

I would re-check that engine again as most larger school buses in the Y block era I have seen were F-600's that had 292 engines and if had a 4 bbl carb had the ram horn manifolds as the steering boxes were in the way for the car type dual exhaust.



2 bbl carb engines had single exhausts.



If it is newer than '61 or has been changed to a newer than '61 engine it could have a steel crank also.



I don't think the Lincoln Y was used until the F-700's and heavier.

Also earlier Ford/Merc Ys have the 7 or 8 vertical ribbed valve covers, not like those in the photo. Another way to check is that the Rams Horns in the photo have angled (about 15 degrees) attachment bosses or bolts. Ford Ys have horizontal plane bolting. They don't interchange.
