I Would like to ask a few various questions about tuning my 1300 dolly engine. currently running as sweet as a nut. But personally would like to give it a fair few more horses and hopefully gain a little more torque.
Ive just found this tuning guide on 1300 spitfire engine tuning.

Insurance won't be an issue by the time the modifications will be completed. as I am begining to stock parts away over the coming months, So i have all the parts ready to fit over next winter (2012 winter time)
I have had a look at the various cams,rocker shafts,and cylinder options (tufftrided and gas flow idea's)
This will be my first attempt at seriously modifying a classic car engine (however i will have my grandad and his friends to help me fit etc)
If the above tuning guide is a good guide to follow I may just follow the guide (possibly make one or two alterations to my setup.
It will be my daily runner when it has been rebuilt. so I would ideally like reliability combined with a little more torque and BHP.
I had thought along the lines of:
Cylinder head converted to unleaded
uprated valve springs
all ported and polished
triumphtune 83 deg cam with uprated rocker shaft
new piston rings
new small end bearings
new big end shells
new big end bearings
clean the oil strainer and other parts that will be staying
1500 inlet manifold and exhaust.
(possibly an oil cooler..)
as for the gearing... I would like to change it but currently don't know which way to go..
as motorway journeys etc do seem to be stressing the engine.
But with the new parts (going on the guide above..) should hopefully be producing around 110BHP or their abouts.. so..
Would it be too much to ask, for the occasional "enthusiastic" drive capabilities that can still cope well on the motorway? id been thinking of a happy medium eg 1500 or 1850 diff and or gearbox?
As for the brakes..Upgrading from original 1300 single line brakes? Someone had suggested "trackerjack's" brake conversion but i would like your opinions on this..
It will hopefully be coming off the road next winter,for a complete strip down and respray and rebuild with a much punchier 1300 lump (same engine but new uprated guts). (staying the same pagent blue,but with various black items to tone things down.
As or the suspension,think thats sorted with the uprated 1" lower springs and dampers available.
Any other suggestions and idea's are more than welcome... as said "im a n00b" to triumph tuning
