You'd need a crankshaft with a shorter offset between main bearings and big end bearings. You'd also need taller pistons so that the crown reaches the original point in the bore in order to maintain a usable compression ratio.<br>

Ha! When I thought about this question for some reason you needed to bring the head to the pistons by making the block smaller not bring the pistons to the head by making them bigger <!--EZCODE EMOTICON START :rollin --><img src=http://www.ezboard.com/intl/aenglish/im ... s/roll.gif ALT=":rollin"><!--EZCODE EMOTICON END--> <br>

1st question Why?.<br>
<br>
Forged crankshaft with shorter stroke with con rod's to suit,<br>
<br>
And then forged piston's if your going to all that expensive.<br>
