help i blew me engine up last nite it decided to pop a rod or something but it put a hole through the block by the alternator now i want an engine that can take mega power

has anyone got any idea wot spec i can run and where the best places are for parts ie steel rods etc cos i havent got a clue being new to this

ive thought bout going the zvh way but so many people have bad comments about it saying its unreliable etc

if anyone can give me advice it would really be a great help

thanx
