Hi everybody new member here and was wondering if any of you guys could give me a bit of advice? I was wondering if i could use a standard 20 block pinto in place of my original 205 block? the 20 block has been bored by 1.0mm and had a slight skim. i will be running approx 380bhp no more! i will be using cosworth rods pistons crank basically all cosworth internals. i know these are not as strong as a cossie block. Any help would be much appreciated. Thanks.
