The joys of shim's!
I reckon the 288 will have some nice power after 4200rpm!
Try & start with the cam pulley in a neutral position first. Then play around with it.
You'll notice a massive difference if you fully advance it & fully retard it!
I think I ran my 270 a couple of degrees retarded on the race track to help with top end power & top speed.
But on the street I ran it alittle bit advanced to help with low down torque with driving around in traffic etc.
Nice to meet your old man at the Jamboree too!
Had a good old chat.
