OK, Rich (zentac) popped round tonight after work and we decided to start attacking my old engine.........I can confirm it is poorly sick!
However, if I can run a 12.789 1/4 with it as it is.......well there is more to come!
Derek....what are you messing about at?!
One tip, if you up the boost - ADJUST YOUR FUELLING
Here is the engine with the rocker cover off..........we didn't know it but we could have worked out here one of the reasons why my engine was running on 5!
