  1. Has the front suspension been thoroughly greased? Pack a lunch, bring a Shop Manual,and don't get out from under until each zerk show grease going where it is supposed to go. Special attention to the steering gearbox. It requires a special semi-liquid lubricant and they're almost always dry. Again, Shop Manual adjustment of the PS valve at the Pittman arm. Check each of the six or so tie rod ends for play. Check the center pivot bearings for wear. Check wheel bearings for correct play. Has the front suspension alignment been adjusted? By modern standards, the Studebaker front suspension design has insufficient caster to self-center at speed. Crank in all the caster the adjustment will allow. Does this Avanti still have the original steel wheels? What tire width are the new tires? Vibration at speed which comes and goes is almost always a tire/wheel balance issue. First, switch front and rear tires. Does this change anything? jack vines
  2. Not all. IIRC, the R3 heads used the same cope and drag boxes as the regular heads, but with different core patterns for the ports and combustion chamber. Some of the R3 core box patterns were salvaged and IIRC, Lionel Stone borrowed the intake port portion when he was trying to get an aluminum R3 head into production. Part of the problem with that attempt was the cores were for iron and aluminum shrinks 50% more when cooling: Iron 1/8" per foot Aluminum 3/16" per foot jack vines
  3. https://www.motortrend.com/vehicle-genres/studebaker-avanti-history-photos/?wc_mid=4035:22453&wc_rid=4035:999826&_wcsid=2B52DB7F006D00EBEF97E8EE2C6599DD7F16BB03CD80237A jack vines
  4. FWIW, factory AC integrated into the dash was still uncommon in the early '60s. Most of the underdash units were aftermarket, FrigiKing, Rapid-Cool and the like. The York piston was the generic AC compressor first used on the 1939 Packard and still used for most of those units through the 1970s. As mentioned above, unless originality is the goal, there's no good reason to go with York and several good reasons to switch over to a modern rotary compressor. jack vines
  5. Paxton sold so many R3 permutations over the years, it's impossible to know what the customer was told and when. In addition to running out of R3 heads, they also used up all the R3 connecting rods and there were several bitsa versions sold with stock rods. jack vines
  6. You don't specify what needs fixing. If it's just replacing the motor, that's one thing. The bad news is the Avanti window glass is too long and heavy for the motor and mechanism used. The weight soon destroys the motor and when the motor is repaired a couple of times, the forces begin to rack and crack the door inner structure. Then the linkage gets worn and damaged. jack vines
  7. The most common fail is the tachometer. The sending units almost always fail and are difficult to find. The good news is the current production S-W tachs don't require a sending unit and will bolt right in. The easiest fix is to buy a complete set of new production S-Ws and replace all the gauges. jack vines
  8. Since Stewart-Warner was the OEM supplier, the Avanti guages are the most common design ever. While those with the red pointers are not always available, one can always find an S-W gauge which will bolt in. jack vines
  9. When the in-gear carburetor curb idle speed of an automatic transmission is properly adjusted, the additional load when an AC compressor kicks in will often stall the engine. The throttle kicker has an adjustable stop which allows it to be set to maintain the same idle on or off AC. Back when I could not find an Avanti part, I fabricated one from a GM u-pick unit. They're pretty much universal. jack vines
  10. Live and learn, indeed. I had been under the impression only the first few '63s got stuck with that POS 3-speed. Now we learn they also used it in some '64s. So the 4-speed was always an extra cost option? jack vines
  11. Old query, but FWIW, my Avanti had Daytons with severe surface rust. I had them sandblasted and powdercoated gold. Since the car was gold, it looked right. For other body colors, there are choices of chrome, silver, and others. The process was inexpensive, successful and has lasted well. jack vines
  12. We've seen both here, so it would be interesting to know how many round headlight cars were converted to square, "to look like the latest style" and how many square headlight cars were converted to round "to get the original, classic look." jack vines, who prefers the original recipe, but owns the Barris custom with quad round headlights.
  13. The flywheel ring gear on a V8 tends to come to a stop in one of four positions and most of the wear takes place there. It was common practice to remove the ring gear, flip it over and reposition it 45-degrees to the original position; all new wearing surfaces. jack vines
  14. "Stand up" depends entirely on how often you lay down the rubber. Even a strong R3 does not make 300 lbs/ft of torque low down on the RPM. An adult-street-driven R3/World-ClassT5 combination would last forever. A season of drag strip use with side-stepping the clutch above 3,000 and flat-shifting might kill it. jack vines
  15. Yes, No, Maybe. How it's been stored and in the humidity of MN, makes estimating worth a real crapshoot. Pulling a number out of the etheric without an examination assumes too much. FWIW, I was given a similar NOS Packard 320" fitted block and pistons which was from CA and was still usable as was. A customer sent us a fitted Champion block which had been stored in Alabama and nothing in it was usable. The rings had rusted to the cylinders and corroded into the pistons. The block had to be bored .060" over to clean up the rust pits. Suggestion; wipe down a cylinder with an oily rag, knock one piston out and show the prospective purchaser the condition of the cylinder, rings and pistons. jack vines
  16. So yes, Chevrolet V8s of that vintage were known for flattening the cam lobes. And yes, the cam can be replaced with the block in the frame, but as mentioned, there are tradeoffs. jack vines
  17. Well, there's no way around needing a bell housing, a flywheel, a pressure plate, a clutch disc, a pilot bearing and a hydraulic clutch kit. How much you pay for them, whether you use OEM or aftermarket is up to you. jack vines
