164 S v 164L

[C M Smith <cmsmith@domain.elided>]

Here we go. The S has hotter cams, a revised AMM, a slight difference in 
the Cat (two pipes in two pipes out whereas the L has two in and one out, 
but big deal, the S Cat goes into one pipe after that anyway).

The L has 16 less horsepower but only 5 lb ft less torque.

The biggest difference is that the S was attached to a gearbox with a 10% 
shorter final drive. The hp gave no advantage and the torque advantage was 
insignificant compared to the gearbox difference. The L engine is actually 
very well sorted and the taller gearbox allows the car to be really driven.

Bottom line: the S wasn't worth the money.

Ideally you should put the S engine into an L to get the taller gearbox 
ratios. Acceleration will be very similar due to the torque figures (the L 
engine is very efficient so Alfa had a hard time improving it for the so 
called S or Sport version)
