I just changed my 305 to a 350 i got all the parts to make it work but one i need the prom or the computer chip that plugs in to the ecm it self were can i get one of these? all bone stock by the way thankyou iv been serching for about a month and havent getin any answers

 

if you are still running the stock 305 injectors you are gonna run into problems. One problem is you are gonna get a spark knock meaning you aren't going to give the cylinders enough fuel and the picton knocks back and forth in the engine. Next problem is you either need to get new injectors (very expensive) or get your prom tuned. I am in the middle of getting my prom tuned by howell efi in michigan ( i am in delaware and send chips back forth through mail). You can also look at southbay injectors and they might be able to help you out. i did a 305 tpi to a 350 tpi and i am running stock 305 computer, knock sensor, prom and injectors. I have a bad spark knock and i am getting it worked out as we speak.

 

Question for 87SnowFlake:

I too did the 305 to 350 swap and now have a 350TPI with the stock 305 computer. Any ideas where we can get the 350 chip??
