I got it from Camping World and they said it was a small block 360cu engine, not. It is a big block for sure. Engine runs,starts like new.
Distributor is in front right side engine.
By the way, welcome to this thread. I hope we'll hear from you often and you'll become a regular.
Distributor in front, towards radiator = big block.
Distributor in rear, towards transmission = small block.
Sparkplugs in middle of valve covers = Hemi.
That's it, all you need to see to tell which an older Mopar V8 is.
It's very unlikely there was an engine swap somewhere in the past. Because, you have to also change transmissions to go from a small block to a big block or vice versa. The bell housing bolt pattern is different and, on automatics, the gearbox case and bell housing are one unit.
Just as with the V8 engines, you can tell whether an automatic transmission is for a small block or big block by measuring how far apart the top two bolt holes on the bell housing are. On big block transmissions, the bolt holes are closer together. On small block transmissions, the bolt holes are farther apart. (Can't recall exact dimension, because I have enough experience to tell just by looking.)
By the way, many people think the "A" in A727, A518, and so on, means automatic ... it doesn't, it means aluminum case. When Mopar introduced automatic transmissions back in the 50's, they had iron cases and the bigger, heavier duty one was sometimes listed as just 727, with out the A. The TorqueFlite label started with the iron case versions and was carried over to the aluminum case versions.
If I get a chance, I'll try to track down a source for a new big block dipstick for you.
