if i got an engine number off a 205 block engine could some1 here tell me if its a thick or thin walled block?
ive been told that there were 2 different 205 blocks, a thin walled one that can take about 350 bhp and a thick walled one good for 500+
is this true?
and if it is and i put up the engine number could some1 here tell me what it is?

cheers
