it's always a question of what you ultimately want from the motor.

Like i said before if you go for 7.2:1 you can run 500+ bhp, but the less power you run through a motor with this comp ratio the flatter the motor will feel.

If you are sure you only want a max of 400 odd (ample i would think)!!! then go for a ratio of 7.6:1 and enjoy the hassle free???? motoring of a low comp motor !!!

p.s. go for the cosworth racing pistons if you can afford them !!!
