  1. Do you still have a 401 core with a Dynaflow crankshaft to go in it? Both the block and crank do not have to be useable. The core would need used main bearings to mount the crank.
  2. Converting gauges to 12 volts is relatively simple. Runtz regulators are a simple way of doing the job, however the diodes they use will probably get warm. Especially when the gauge sender is at zero ohms (full on gauge). You can use resistors to drop the voltage, but they will also need to be 5 watt resistors or higher. And the gauge will not be very accurate. The Ford constant voltage regulator does, in fact, send out a 50% duty cycle, which averages 6 volts from the 12 volt input, but with GM balancing coil type gauges the Ford regulator will cause the needle to oscillate. You could put a capacitor across the output of the regulator to ground to filter the oscillations out. My preference is using a voltage regulator such as a 7806 or a LM340-6. These are very simple to use and are available from Digikey.. To install, connect the +12 volt ignition to the leftmost pin, the middle pin or tab is grounded, and the rightmost pin is the output to the power pin of the gas gauge. Install 1uf non polarized capacitor from ground to input pin, and one (same value) capacitor from ground to output pin. You won't be disappointed!
  3. Yes, not concerned. I don't need a rebuildable engine, just interested in the dynaflow interface to the nailhead.
  4. Do you have 1957 to 1963 nailhead block core with dynaflow crank installed? Does not have to be rebuildable, but crank flange must be ok. I am in Kansas.
  5. Try this link: http://www.ebay.com/itm/1964-1974-Buick-Red-Engine-Paint-Spray-Can-EP644S-/182164202183?epid=657985620&hash=item2a69d522c7:g:m2kAAOSwFMZWtfZI&vxp=mtr
  6. Use a small pipe wrench to remove the converter drain plug(s). It will bite the rounded head and should be able to remove.
  7. The 57 and 58 Olds 371 engines are different from the 59-60 371's. The later version was a de-bored 394, which had a different deck height.
  8. 1957 Cadillac's used Bendix Hydrovacs. Perhaps that is what it is for.
  9. If you still have the original accelerator start mechanism, you may be able to use that switch for kickdown. That is of course if you use the carb that has the switch.
  10. I would check the brake switch first. Check the terminals on brake switch for 6 Volts to ground. One should have this. If you have 6 volts on switch, short the two terminals together and see if the brake lights come on. If so, then the switch is either defective, or out of adjustment. Next would be the headlight switch. This is the control for parking lights, head lights, and instrument panel lights. Verify the switch is wired correctly. Blinkers are fairly simple too. Pull the blinker unit and again (with the ignition switch in ign position) check for 6 volts on one of the blinker socket terminals. If 6 volts is there, then you can jumper both terminals together and see if rear lights lite up with turn signal switch in left or right.
  11. If you need a starter relay, why not just find a four or five pin modern relay and wire it accordingly. The relay doesn't need to be a heavy current type, as the solenoid does most of the work. But it must be one that has isolated coil contacts for the accelerator start stuff. You probably can stuff it into the old relay's case for originality look.
  12. Don't recall, but Buick changed over to 12v in 1953. However the Specials with straight 8 might still have been 6v.
  13. Building the "guts" for an electronic regulator is not all that difficult. Make it short and sweet, a switch-mode voltage regulator ic will work fine for both voltage and current regulation, and when connected to a pass transistor the transistor will not allow the battery to drive the generator when engine is off. I have worked on a universal 6 or 12 volt, pos or neg ground circuit, however my time and money are limited at this time. Some time in the future I will finish it up and have one of my friends try it on one of his 12v pos ground Brit cars. (Lucas regulators are more weird than our American units) Another point to be made is that normally there is a capacitor across the battery to ground on the regulator. This helps reduce arcing in those old style units.
  14. Looking to buy a 64-66 ST (or SP) 400 flexplate for 401 or 425 Nailhead. Please PM me if you have one for sale. Thanks
  15. Another thing is to check the grounds of the generator, regulator, and battery. There should be NO resistance between any of them. If the regulator is not grounded well, then the voltage regulator will not work correctly and give you the issues you are experiencing.
