I have a complete tuned port setup with either base. Comes with computer and wiring harness from an 85. for use with hei. The cool thing about this harness is that it does not have connector into the firewall on the driver side. but it does have the connector into the underdash section. would need to cut and splice a fuse box in to use on any vehicle that you wanted. 450 shipped OBO. I will have another one up for sale very soon as well for a 89 IROC.

 

hey id be interested in the one for the 89 iroc

if its a 350 with wiring harness

id pay for it
and if ya happen to have a 700r4 tranny that would be excellent

 

It is a 350 Harness. and I do have a 700r4 doesnt work though so I dont think that you want it (lol)
