A little off topic. Is there a place I can read up on them and compare so I can see first hand what is better about a SD set-up.

85 is the year of maf to avoid. well if you already have maf then run it. no need to get into a sd swap if the maf system you have is working fine.

in 85' they used the MAS module for burnoff control. the module is expensive to replace when it goes south. with the later 86-89, burnoff control was also intergrated into the ecm instead of using a seperate module.
yes the 85
<-ecm was slow.
