OK thaks for the help So far I know about the piston problem, the pistons have been machined on top as this was going to be a supercharged engine (hence the lower compression ratio),Im just deliberating maby leave as N/A and bore out to 83.5mm,
I really need a answer on the flywheel clutch as to what flywheel to use as i dont fancy stripping the running engine out to find out the size !!!
