That's a bit like asking how long is a piece of string. You haven't said how lift @ TDC the 285 cam has. For example, lets say it has 0.080" lift @ TDC. Given the acceptable safe limit for an RS engine is approx. 0.055", you'd need to take a minimum of 0.025". If I was I doing it, I'd take out 0.040" minimum and deck the block to make up for the loss in compression. |

you can use the 285h cams without needing to pocket the pistonsif your car has had a head skim though it may be worth checking the valve clearances for piece of mind ________________________________________ *R.I.P Pete Sims* |
