Did you advance the timing or something mate?
Details on this would be much appreciated

yes i had it on the dyno and marked the distributor to the block if you like to show where it originally was, then tweaked it a little, gave it a run, see the power increse or decrease, made sure it was not pinking etc, and then just keep tweaking till your highest you have found, really small amounts of adjustment and depending if someone has already been there and done it but sometimes you can squeeze a few bhp, nothing major tho
