Some updates. Got the ignition sorted, 35 total at this point with 25 initial Took adjustable MSD rotor to get the phasing right. 8" dual diaphragm booster is still not up to the task, partly because contrary to advertised text, that MTS#15 makes enough vacuum to run power brakes, it really does not. Will go with 9" dual and electric vacuum pump cuz i dont like Hydroboost for no particular reason. Another development is, that i need to throw in a 2400 stall converter, in order to be able to drive in city traffic. Idle @950 means, that my current converter hooks right up and engine wants to die. Advertised operational rpm-s being between 1500 and 5000. So i decided to go with B&M Nitrous Holeshot 2400 and because i do not have too much confidence in ancient stock flexplate, went with Hays 14-010 Cadillac specific SFI approved one. The only setback being, it does not exist in Europe so i will have to wait another 3-4 weeks for it to be delivered. Well, time does not matter much anyway nowadays
That should be a great converter. I have the TCI version in mine a I really like it. It does flash to 2900rpm. The flexplate that’s installed in my car looks the same as the Hays picture on their website. The mini starter only engages 1/2 of the depth of the teeth. I bought a PEP SFI plate to install this winter when I fix my rear main seal. The offset on it measures the same as the stock plate.
