There would be 0 backlash on a hydraulic cam. If you asking about piston to valve clearance, you would want about .100" , but shouldn't need to worry about it if it's stock.
Hydraulic lifters would be STOCK from the factory. On the 84 engine.
Stock 350's have hydraulic lifters, so feeler gauges aren't needed. Get yourself a Chilton's manual or similar and read up on the valve adjustment process.
If you're going stock lifters, they're hydraulic and you don't mess with them. If you've replaced with solids (which is a really good idea), you'll need to get that information from the people who manufactured the lifters/cam.
If it is still factory stock, then your question is yes.
If you have a 2001 or newer engine, it comes with roller lifters and roller rockers from the factory.
The stock ground clearance for a 1973 Chevy Nova is typically around 5 to 6 inches, depending on the specific model and suspension setup. This measurement can vary slightly based on factors such as tire size and any modifications made to the vehicle over the years. Always check the vehicle's specifications for the most accurate information.
"Clearance stock" is a term that refers to items that have been greatly reduced in price in order to rid a company of inventory. For example, HP had several tablets called clearance stock that sold at 75% off.
I would say finding aluminum patio furniture particularly the clearance stock, would be much easier finding in stores. Because in stores, there is a lot of clearance stock at great affordable prices, as stores want to get rid of the old stock and get new stock in. Whereas online, it is much more difficult to find clearance stock.
Yes, you will need an E-curve cam to have the correct profile for EFI. Edelbrock, Comp Cams and other aftermarket manufactures have cams for such swaps, or you can find a cam from an 88-newer 5.0L/302 that has EFI from the factory, in doing this you will also need to change the lifters in your engine as stock 88-up engines feature hydraulic roller lifters, any flat tappet lifters will wipe these cams so its best to do the swap.
A 2002 Chevy duramax has 300 horsepower stock
As i believe, from experience of owning one, 1984 is when the hydraulic clutch came into place. You shouldn't need to bleed the clutch on an 83' S10. Not unless its not the stock transmission.
