42bill Registered: 09/19/03 Posts: 4748 Loc: Portland, OR	Not the exact same question - but - from the hotrodders forum... Hi all, can anybody out there suggest how to increase the power and RPM on a 270 in-line 6 cylinder GMC engine, I have heard about fitting a 302 head but then this will require new pistons as the 270 ones are domed what sort of pistons would be needed to give a reasonable compression ratio. For increasing the RPM does anything need to be done to the crank or rods ? Is the 302 head ok for more RPM ? All the "answers" and advice suggested getting ahold of Patrick's in AZ. Probably good advice.... Bill. _________________________ www.rdgsons.com/vcca/toyz.jpg
