Well, it isn’t exactly a new engine but at least it’s in one piece and supposedly runs. I picked this up locally at a very reasonable price of $225 Canadian pesos, that’s about $170 US real dollars if anyone is interested.

The engine is a 1972 18V long block that appears to be in decent condition. A minor strip down hopefully will confirm this.

Of course this opens up another can of worms. By 1972 a different transmission was being used in the MGB so some of the rear engine components are different. The engine rear plate accepts a more modern starter that engage a larger flywheel and a bolts to a larger transmission bell housing. Fortunately the older 67 parts just bolt on or, one could upgrade the transmission. Not at this point!

By 1972 there were many changes internally to these engines as well with new connecting rods and pistons, a milder camshaft and a completely new cylinder head. Is this a better engine or has it been changed to meet the ever tightening pollution regulations in North America? I expect a bit of both.

Time to take a look at the internals!
