Yeah i built it myself i did it for a customer who came in with £2000 and asked me to make it go faster . So i ported and polished the head, fitted larger valves . i put a rally cam with fixed lifters to give the torque .With the bottom end i stroked the crank.Thats were you grind it offset so that it gives a longer stroke .i lightened and polished the con rods aswell as the crank and flywheel .With the pistons i polished the tops and shaved the shirks so that they were razor sharp.This is so that when the piston goes down the bore it cuts the oil out of the way rather than pushing it , hence it goes much much faster .The last thing i did was to chip it. It was a very mad car and if you wanted to it would wheel spin in 4th gear .
