I should be able to see that with light hooked to each plug wire one at a
time, right?

Its very possible, with the 4.3 calpak in, truck belches black smoke..never
thought to check timing or fuel spray pattern at the time...
< What happens with an 8cyl netres?>
Good question, Id almost be willing to bet money it would work though, esp.
if it were from a 305 and cyl sel. set to 4...
<The rock steady and climbing to 16 deg is good. I don't understand the 0
deg & 6 deg under the differing conditions. I'd expect them to be the
same. >
Could also be a diffrence in distributors...Today, Ill see if parts store
has v8 and 4 cyl dist. in same store, and go stare at em a while...
<If you are looking for hacked 4 cylinder files, I am not sure which
fourcylinder you are talking about, as I am here in 'mid conversation' I
would try this website : www.geocities.com/jeremygonyou
He had a sunbird 4cyl turbo, he does eeprom editing and hacking, he may have
some info listed on his site for his Sunbird 4cyl. Try there, and good
luck!>
Id guess that is a mpfi system and incompatible with my single injector tbi,
but ill look into it later, thanks...
