Removed the old choke heater and electric choke hardware. Installed the block-off, Edelbrock 8901. Unfortunately I had neither the right choke coil spring nor the right linkage. With each incremental step of engine upgrade I'm trying to replace things with the 1970 LT-1 spec parts. I think this step won't be good until I replace the Edelbrock Performer intake with the right stock part. Unfortunately, eBay thinks those manifolds are made out of gold. I'll keep looking. And in the mean time, I'll patch together a divorced choke setup functionally equivalent to that of the LT-1, if not yet with the proper part numbers.

BTW, if anyone has part numbers and/or close-up pictures for the carb/choke setup on a real 1970 LT-1, please post. I thought the parts pictured would do it, but it's looking like I didn't know what I was doing.
