What engine have i bought

Inherited My fathers '62 ser2a a year ago although origanally petrol it was diesal when my dad bought it in '85 it currently has a 2 1/4 na diesal 3mb came across an engine of a friend of his a while back and it was cheap so bought it who said it was the same 2 1/4 on closer inspection it looks similer but the exhaust manifold is different the sern of the engine is 368020@@@@ have i bought a 2 1/4 na 5 mb out of a late series 3 as the serial numbers in the manuels i have are from dec '63 and march '69

368 doesn't appear on my list, but all the 36's listed are 5 bearing. It may be something odd like a taxi, but should fit. I would expect the early manifold to fit.

cheers Davec.
