following the recent rolling road shootout day at TnR, here are the figures for my 1300 crossflow
standard bore/stroke 1298cc block and pistons
bcf3 cam
big valve head, ported and polished (was told around stage 2, but dont know for sure)
lightened and ballenced bottom end and flywheel
32/36 weber with ramair filter
4-2-1 manifold (not sure what make but it isnt an ashley) single box 2" system

i cant remember steves exact comments, but it was running very very rich to the point it goes off the scale (and filled the place with black smoke), and something goes a bit odd at the top end, most likely cause being the dizzy, which i have suspected was nackered as it went through a phase of eating rotor arms and caps,
when i first bought the car just over 2 years ago it would very happily rev upto 7k, so there is obviously something worn out... most likely switch to megajolt, and maybe twin 40s although this might be overkill :D

all in all i was very happy with its 77.9bhp and 75lbft, should be very reasonable with a decent tune up and after the fueling and electrics are sorted out, hopefully it will last me another year or so untill i upgrade.
i think the high transmission losses are probably due to running a 3.54 diff which is alot of work for the small engine, this will be changed when i go to 5-speed.
