Agree with the winch. Especially useful for hauling broken cars on. One of t=

I can tell you that I already have a GT6 with a good flexible power band and=
good reliability. It lacks quickness however, due in part to the TR6 engine=
which is not highly tuned and I'm sure the gearing could be better (3.27 r=

I always say that you want to pick an intake duration for an RPM range that=
you're willing and able to turn. We all know what happens to a stock TR4 cr=
ank which sees >6,000 on a regular basis. Some guys want a cam good beyond 7=
,000, but they are just not willing to push it that far. Nowadays I'm more o=
f a street car guy, but still like to have power. I don't believe the choic=
es should be to do nothing or go all the way to race specs. =46rom 1968 on T=
riumphs were severely detuned to pass emissions. Compression ratio and dura=
tion and hence cam overlap at TDC were reduced. For example, the early TR25=
0/6 had 193 degrees duration (measured at 0.050), while the TR4 was about 21=
5 and the early PI TR5/6 was 226. It seems crazy to rebuild a street car of t=
his era to the original specs. Bumping the compression ratio by a point and=
increasing the duration to something like 210-215 will make the engine the w=
ay it would have been without emission restrictions. I would not feel guilt=
y about polluting the planet, since most of these cars see few miles annuall=
y and most of the other pollution controls (e.g. ignition retard) probably q=
