New 4000 Coan stall convertor
New flexplate - 727 int balance cut down to suit 904 trans
Cut down and fit pushrods ( includes a trip to Yorkshire and a trip to London chasing parts ).
Finished installing 7 pm Saturday
Took it to track for a shakedown on Sunday and stalled it on the line, nursed it away and just plodded down the track ... still managed a 113 mph so it should run 10`s once I sort the niggles out ... reckon carb is too small ??
This week : make some proper headers + fit Demon 850 ready for the Nats
