hi
i finally got all my parts in for my 89 Formula
Holley 670 TBI, Holley TBI intake, Eldebrock Headers and Y-Pipe (3"),
Crane Cam (110 lobe sep), rebuilt 350 block, ect....

my question is for the guys running a similar setup, or anyone who knows
i was wondering which 350 knock sensor you guys are suing?
i can get either the one from a 350 TPI, or another one that seems to come from a truck or caprice
my thoughts would be to go with the one from a 350 TBI big car or truck, but i wanted to make sure
part numbers would be cool too since i am ordering from my local pontiac parts dept.
thanks
Joe

 

I cut/pasted this information for my own application!

I recently swapped a 350 in place of my 305 in my 92 RS.You should be able to get by with just the bigger injectors and an adjustable fuel pressure regulator....as long as the cam isn't huge.
You should change the knock sensor and module as well.
350 Truck TBI knock sensor:10456288
350 Truck TBI knock module:16128261
