I'm looking for info, anyone who has experience or advice with a 45D4 distributor in a 1275 engine. I have a recently rebuilt 1275 (1974 vintage). The 45D4 was stock to the 1500 engine. My car is running good but I'm trying to fine tune it and set the proper timing. All the research I have done suggest the timing for a 1275 with 25D4 distributor should be set to 13 degrees BTC @ 1000rpm. The 45D4 in a 1500 engine should be set to 2 degree ATC. If anyone out there has worked with this setup , the 45D4 in a 1275, I would appreciate any info/ feed back you can offer. Thanks, Kevin
