I have been loading up the forum with questions. I appreciate the responses. You guys have really helped me along with this project.
1975 L48 Vert 4-Speed. Partially restored. Mechanic died halfway through. I took it over.
I finally have it running pretty good (thanks Lars and Jebbysan). Today, I took it off the jack stands and backed it out the shop and forward back into the shop. Wanted to see how the clutch and transmission engaged under a load.
The clutch catches very sharply about an inch or two off the floorboard. It is a brand new clutch and flywheel assembly.
Question 1: Should it catch so closely to the floorboard.
Next, I am having trouble grinding Reverse after moving the car a little. I have to slip the transmission into Second gear, then it will smoothly go into Reverse.
Question 2: Does the Reverse grinding mean I should adjust the clutch pedal to give more distance between clutch and plate?
I have not had an old manual/spring-clutched tranny in thirty years. Please give me a little guidance here.
Using your fingers press on the clutch pedal should have about 1.25" play.
Reverse is not a synchromesh gear, place in any forward gear before engaging reverse

“Reverse is not a synchromesh gear, place in any forward gear before engaging reverse”
Now that is gold nugget of information!!!
Grinding going into gear and a low engagement point both are signs of a clutch not completely disengaging. C3 Corvette's are touchy about which clutch is installed as the amount of total "throw" is limited. Less than some cars. Which new clutch is in your car?
Many threads on here in the past discussing this very issue. Certain brands of clutches simply do not dissengage enough with the limited travel afforded by the Corvette clutch linkage.
I would try readjusting the clutch with less pedal free play. But not less than 3/4 inch. If it still doesn't disengage completely, pull it out and replace it.
There are numerous threads on here as to which clutch is preferred.
And which ones simply do not work.

I got this car halfway reassembled. The clutch assembly was already installed and transmission/shifter in the car. The mechanic passed away two years ago and his small shop has been dissolved with the estate. No paperwork. Owner is not a mechanic. Short answer - beats me?
However, all forward gears shift smoothly with no force or grinding. When I stop, slip it into second or first momentarily, it then goes easily into reverse. Does that sound okay or may I still need to do more digging?
That information is in the owners manual. I recommend you read through the '75 owners manual from front to back. It is packed with many such nuggets.
I would like to have an Owner’s Manual, but the cheapest I found was $45 here on the forum. Little too rich for me right now. Maybe when we all stop enjoying these Bidenomics!!!

The first place I looked was on the Corvette Central website. 1975 Corvette Owner's Manual: Part #113012 for $15.05, in stock. There are many other Corvette vendors that also sell this documentation. You can also find this stuff on eBay.
You might also consider picking up an assembly manual and shop manual as well. All this will save you a lot of time, trouble and expense. Think of them, along with this Forum, as good investments. As for myself, I learn many things from them on a regular basis. I read many questions here on the Forum that are answered in the Owner's Manual, which is the most fundamental literature for a C3 Corvette owner. This is particularly true since the C3 is now a half-century old.
I sold two C3 cars over the years and each time I placed the appropriate Owner's Manual in the rear compartment so the new owners would have them available.
