im doing a 305 350 swap and i need these 2 items. let me know if you have one and we can work something out. (has to be out of a 350 tpi 5speed)

 

if you have a tpi 305 you have the 1227165 ecm already. I can help you bye reprograming the memcal if that is of any help.

 

Right right I realized that after doing some more research. I need the esc regardless though right? It's 85.00 off napa so I'll probably just buy it new. As far as the prom goes, don't I need a 350 prom as a base even if I do tuning in the future? I read that a 305 prom can't be changed to work with a 350. You need the 350 prom

 

if it is maf the i/o buffer and netress are the same its just the programing. If you were dealing with tpi speed density the knock filter soldered on the memcal is a different frequency from 305 to 350 and will not retard the timing correctly if a knock occurs. you will still need a 5.7 esc. here is a good deal on a ac delco 216-47

A knock sensor is ac delco 213-324 for a 5.7L and I believe its a 213-325 for the 5.0, if you are looking for a memcal The 89 has a lean cruise but also uses vats.
