TSC questions
The 71 C10 had a motor swap years ago before I bought it. It is now running a 350 from a 72 GM A-body car with an Edelbrock Performer intake and 600 carb. I had found a set of three wires laying across the PS of the intake and are what I believe to be part of the old Transmission Spark Control system. Seeing how mine no longer has the original carb and I could really care less about the originality of it, I am going to finish removing the wires and relay. I know I could just leave the sensor in the RH head, but if I removed it, what kind of plug have you guys used? I am assuming it is also threaded into a coolant Passage?
Thanks for any info. Although I grew up in a GM family, it’s been a long time since I have had one.

Re: TSC questions
A '72 head will have 1/2" NPT threads in them.

Re: TSC questions
That’s perfect. I know it’s not hurting anything being there, but I am going to drain the coolant and flush the system so I figure it would be a good time to make some changes. Thanks Captain!
