[QUOTE="AutoBlackie, post: 584307, member: 3946"] Way to go Acoustic! Anyway, from my little experience, here is what I did when adjusting the pulleys. 1) Document every adjustment, note down its effects. 2) Adjust in small increments, 1 or 2 degrees at a time. 3) Adjust one pulley at a time. 4) Remember to consider the ignition timing when [color=black][b]Ex. pulley[/b][/color] has been adjusted.- if you do not have a strobe, have to use your ears to listen to pinging. use a no.12 to loosen the nut to the distributor and push down is adv (clockwise) and pull up retard. This is important as you might not be able to feel the change the new setting gives you. 5) Changing the In. pulley setting changes the powerband more significantly (from experience). It is a good place to start as you do not have to adjust the ignition timing after that. 6) Make sure you have time to spare as you'll have to test every different setting you made. 7) Somehow without reseting the ECU you'll still be able to feel the difference (from experience). Here is a recommendation from me for your 272 cams. In. Cam 8 to 10 degrees retard and Ex. Cam 3 to 5 degrees advance. Make sure ignition timing is advanced set to bout 12 degrees after that. This will reduce overlap, and help smoothen your idling. If you don't like the setting, it's oK, Remember? it's adjustable : ) [/QUOTE]
