Re: [Amc-list] finally got pics up

The problem is the block design of the AL engine is just enough different to say there's no way to be sure the filter will clear. You'll just have to lower an AL block in to see. I just went out and eye-balled the 65 American I have with an L-head and filter on the oil pump, and the engine bay of a 62 American w/L-head I have. The L-head and iron OHV engine are identical from the side covers down. The AL block uses the L-head and iron OHV crank, rods, cam placement, distributor placement (and distributor), and timing set, but the block casting is very different. It may be slightly wider near the oil pump. If it is, the engine probably won't fit -- though it wouldn't be a lot of work to slot the mount holes and move it to the left 1/4" or so. 

The oil pump is unique for the AL engine. The filter is in-line with the block and sits horizontally. The filter on the iron engines sits vertically, canted to the passenger side at an angle (perpendicular to the side of the pump). The pump on the iron engines angles down to the right in the 20-25 degree range. The AL engine pump goes straight out the side of the block. This is crucial! Take a good look at the oil pump in your American now. That pump just clears the idler arm bracket IIRC. The AL pump will be up about 1-1/2", and stick about 1/2" further out to the right. If you have at least 1/4" clearance between the rail and pump after taking into account that extra 1/2", it will fit. The horizontal filter saves the day! The filter and pump stick out about the same distance as the fuel pump. The angled filter is what kills using the 65 pump and filter in the 58-63 American body. If the filter were on the back side against the engine like the AL filter is it would probably 
 fit. 

Don't you have a 62 TSM? Take a look at the drawings and photos of the engines and you'll see what I mean.

still not sure if that aluminum engine will work in there or not with that oil pump/filter. tom j. or frank s. probably tell me for SURE that it would fit with just the oil filter adapter (if i could find one that will go onto that filter housing) then i would go for it. would be cool to have an aluminum engine for the little thing. how much weight was lost with the aluminum block over cast iron? im thinking pretty seriously about picking up that 62 classic i found. has lots of parts i can use. aluminum engine, 3spd/od, pannels to use to patch up my rusty spots, ect. sheesh, being broke is a beeotch....
