I just swaped from a 305 to a 350 in my 91RS and I need to change the knock sensor to a 350 one, and the module also.(what module I don't know). I looked at the online GM Performance calatog but can't find the part numbers anywhere or this module that I have to change. Can someone please help me!!!!!!!!

 

The GM HO conversion LG$ to ZZ$ crate engine specifies the following part numbers
A.Knock sensor P/N10456018
B.Module elec. spark control P/N 16128261

------------------

 

Thanks for the info, but I'm not sure it is right. Only carburated models have a spark control module mine is TBI. So I'm not sure if the info you are giving me is correct for my 91. Any other Advice?

 

Funny, my tpi and every other one ive seen from 89 down has a spark module.

 

I wasn't refering to the control module in the distributor. Every car with eletronic ignition has one. Is this the module that I have to change. If so why?

 

No there is a module on the drivers side of the firewall. its called the esc module. Its behind some relays. But Dont know if tbi has it. If it has a knock sensor it should have one.

That is an IGNITION CONTROL MODULE. What you need is just the Knock Sensor, and yes that one posted will work.
