Steven,
I really wonder how streetable you would find a normally aspirated 175 HP TR6.
I friend JUST got his approx. 160 hp engine running. Its idle is less than
perfect.
It might be a matter of tuning, but the PI versions (with a pretty hot cam,
similar to what is
in my friends car) don't require much vacuum to get the mixture into the
engine. A carb engine
just doesn't develop much vacuum with this type of cam. A strong idle is a
real issue.
