I need to know the best way to adjust the valves on a383 stroker with solid lifter cam and how often I should do this.I am drag racing this 73 chevy luv.

You adjust the valves to the cam manufactures hot last specs via a feeler gauge. I would at least check them once a month.

Do you need info on the exact sequence to follow to adjust solid lifter valves (ie how to tell when the lifter is on the base circle of the cam lobe)?

68chevell_ss yes i need to know the procedure for setting the valves and about how often i should do it. i was wondering if there was an easier way than doing one valve at a time. THANK YOU for any info

73luvdrag, I use a book by David Vizard which gives me the sequence so I found a webpage that gives you the same information:

www.centuryperformance.com/valveadjustment.asp

I don't know how much you know about valve lash adjustment but this page will give you just about all the info I can tell you without me having to type it all out. The section "Valve Adjustment the Quick Way:" will give you the exact sequence to follow when setting the lash. My only comment is that I don't set the intake valves all at once and then do all the exhaust valves. When you start setting them you will notice that you will alternate between an intake valve and an exhaust valve each 1/4 rotation of the crank.

Actually there is nothing "Quick" about the "Quick Way" procedure. It takes a little time but that is the cost of running a solid lifter cam and worth it if you do it correctly. Hope this helps!

Sorry, forgot to comment on the frequency of adjustment. I run a solid roller in a street/strip car so I don't adjust as often as one would in a drag only car. I adjust mine every other time to the dragstrip but I'm probably on the anal side and I have poly locks. Hopefully someone with a drag car can input on their frequency.

And as far as I know you need to adjust one valve at a time in order to make sure you are on the base circle of the cam for that valve. You don't want to skimp on this procedure as the consequences of doing it incorrectly will cost you. Have fun and good luck!
