Hi, hopefully someone can share some advice. In a bid to up the power in my 1983 18RC hilux I purchased from my local wreckers what I was told was an 18rg engine. Has twin webbers, extractors and 5 spd for $700. Gets it home and finds an engine number '3T....!' The head looks very much 18RG so now I'm not sure! Can an 18RG head be put on a 3T block. Should I kick up a stink and demand $$ back or should I just try what I've got 'cause anything would be better than an 18rc? The part number on the front of the head is 11111-88260. any help/recomendations would be appreciated.
