While it's fun to fantasize about engine swaps -- with enough time and money almost anything can be done but one need not be so radical to liven up the performance of the B18/20. A 1967 140 has a B18 (109 cu. in.) rated at 115 hp. and is no slouch if you are willing to use the revs it is capable of. A 140 is not a particularly heavy car - my '69 tipped the scales at Watkins Glen at 2700 lbs. With relatively modest mods a lot of performance can be squeezed from the engine already planted in the engine bay. My 144S is an example. With a later cylinder head with 44mm intake valves (my cylinder head must have come from a Canada car as it had the intake rings for a carbed engine), some minor porting and exhaust port matching, a "K" cam, compression ratio bumped to 11 to 1, and a B20E exhaust manifold. With SU's feeding it I've clocked 115 mph on Watkins Glen's back straight (from 103mph as the top speed according to a Road & Track road test of a '69 140 -- and I know that's accurate as I was ticketed at that speed before the mods - stupid me). It's perfectly docile for street driving and still gets good gas mileage (on High Test, of course). That's not to say an engine swap is a bad thing -- I've put 175,000 miles on my VolvOlds -- a 245 with a 1963 Oldsmobile 215 cu. in. aluminum V8 -- but it was a swap that seemed to make sense. The engine and trans (T5 gearbox) lightened the front enough to require lowering the front springs. But to each his own - so dream away. -- Dave
