thank you all, much. i know i need the cam retarded 2 deg if custom, or ret 4 
at the crank if not custom ground. i know i have teh short runner long tube,, 
factory solid cam, 3600 peak rpm. i need please, did i read right the 
message right the cars prior for this set-up were 284. because i will stick 
with factory but that seems high for my stock converter, so the automatic was 
..... help anyone. i have been online for months trying to find out what 
duration the short rams are. i have automatic, and solid cam. short runner 
long tube. i know i can use a 108 centerline..?. or lobe, anyway if a custom. 
but my only problem from all, the cam manufactures is the same answer, i dont 
know......... i know peak, but duration and rams are senstitve i thought.
i know this is probably getting old by now, but i am sorry, you are all my 
last option here. what duration was stock on this set-up, so i can plug in 
the numbers and get this done. i gave up an a different size cam because i 
dont know the math to figure out the exact duration that will still work.
sorry you all, and thanks, tim
