Chris, when I was doing my 35 from a basket I took hundreds of photos of other 35s. Many different cobbled wiring, but I did find 4 cars with the same wire block. So that must be correct Here is the best photo I could find.
You can always restore to original. Done many with no problems. Made new stainless shafts, cast new bronze impellers, made new bushings and packing nuts. No leaks and many still running. This photo is one I did for Dick Quinns 31 president coupe.
33s are model 92. Dick Quinn has the production numbers. I think less than 400. Pierce heads have a larger combustion chamber and would lower ratio on a president. you're referring to 80 and 90 and they are 31. 91 are 32. What are you looking at?
