Hi It’s my first post but I’ve been here in the back ground. Not sure I’ve posted this in the right place
but I’ve had my Cosworth block bores checked at the engine shop ready to build but number one is 4.5 tho at the bottom and 5 tho at the top of the bore and number 2 3 4 are 4 tho the shop said this is fine but I would like a second view on this it’s a 205 block and Mahle pistons on a 0.5 over bore not forged
any help would be great thanks
