I read all the replies and everyone makes good sence, but remember everyone's combo is slighty different. As far as lash on most (not all) solid lifter cams is anyware from .022-.028 hot, really can't go wrong with .025 that will work fine, as I have seen many times peoples "feel" with the feeler gauge is different, many set the lash too loose, you should feel a decent ammount of restistance sliding it between the valve tip and rocker arm tip. Adjust the intake when you see the exh. begin to open and adjust the exh. when the intake is halfway closed, this way the valve you are adjusting is on the base circle of the cam. For my ign. set up I still run a mechanical curve but it comes in quick. I set base timing at 16* and there is 20* spread built in so my total is at 36* and that is all in @1,800rpm. But as we all know timing requirements differ for all engines due to compression ratio's, cyl head design, fuel quality, boost ratios or nitrous, just be safe. Good luck, take your time and it will work out fine.
