Will Mazda B3 sohc head bolt onto a B5 block & what does the compression

[Russell B]

ration end up at? I have this little thing & I'm thinking I should get a "real" car and use the hatchback for club racing, but I want to know if I can just bolt the 1300cc head onto a fresh 1500cc block (because they can handle higher revs) & have a torquey little engine that cost next to nothing to run... I've done similar before by putting 1300 pistons in a 1600cc engine from a 1977 Mk11 Escort & it was a Great engine to drive & I'm hoping to get the same effect again
