I was going through Avanti memorabilia I have to find new homes for since I sold my Avantis before downsizing and relocating and found these sheets from Avanti Motors providing engine specs for the 1970 350/300 engine they started using as standard. I'm sure the specs are standard GM but am providing them for anyone who could use them.

I don't see why it's not possible...just takes money, time and some talent. You would have to add extensions to each gauge wire or things would come off when pulling the cluster. You would also have to make sure of a solid electrical ground for the gauges and lights.

There are no mom and pop oil refineries...all modern motor oils come from the big boys. As long as the oil you choose meets the specs for your particular year car you're good to go. The oil you buy today will be different from the same brand you buy next year as car companies are always changing their recommendations and the oil companies respond. We all have our favorites and there's nothing wrong with that. What may be more important...and that debatable...is using a brand from the same base oils. With dino oils there's paraffin base and asphalt base. They each require different levels of being refined but in the end do the same thing. I understand Pennsylvania grade crude is the choicest oils and is generally refined into lubricants where mid-eastern oil is generally refined into fuels...just the best use of the raw materials it seems. Use the grade oils recommended for your application...use appropriate oil change intervals and you're good to go. One thing I learned from car forums...if you want to start a flame war that costs many lives so to speak...start a thread that questions someone's favorite motor oil...gasoline...car wax...oil filter...tires...most anything they're passionate about in their car care.

Go with a TH200R4 as it has a better spread of gears. It can be built to take prodigious amount of power. I had a TH700R4 in the ‘70 I owned and it was shifting into 2nd gear almost immediately and chirping the rear tires without trying to. Another thing to consider…think about getting an aluminum driveshaft as it reduces rotating mass and weight which is always worthwhile in an Avanti.

Rotary. I was going to say electric as opposed to vacuum…but electric is already in the description.

If I remember correctly...the Shelby Mustang GT-350s equipped with Paxton superchargers had a sticker on the supercharger body with Paxton's name and listing it as a division of the Studebaker Corporation.

The side of the engine and frame the lines run.

Of course it’s possible…but did any actually leave the factory is a better question. I would say no as the oil filter was a standard thing on R engines. I could see an exception made possibly for a special car equipped with a remote filter such as for purposes such as speed runs at Bonneville in a modified non-stock class.

The coolant expansion tank on top of the engine?

Look under the drivers side of the dash at the top left. That’s a very common place in older cars for fuse boxes. The radio may possibly have a fuse in its hot line…depending on the brand.

I’d say Sherwood Egbert as if it wasn’t for him there would be no Avanti. My second guess would be Eugene Hardig as he was in charge of putting it together.

False…it was at the Smithsonian’s Renwick Gallery in 1975. It was about Raymond Loewy’s designs. Renwick Gallery Avanti

I would say true…it spent much of its life on display if I remember correctly.

AM/FM radios were an option for 1964.
