Yes. But you may need to rejet your carburetor and you will need to advance the timing. Vehcile with Electronic Fuel Injection can be converted with a kit from http://www.change2E85.com
Will it run? Yes. Is it safe? No. The materials in the fuel system, carb, tank, lines, etc are not compatible with use with ethanol.
Be very weary of "conversion kits" that do not address the fuel system as a whole.
1. You need to rejet carb, around 40% larger jetting.
2. You need to drop the tank, replace the rubber lines with a viton or other alcohol safe rubber.
3. Clean the tank, it will be nasty after 30 years of various fuels and addtives.
4. Once jetted for E85, you are stuck with it until you rejet for gas.
Yes, it will run on it, but the terrible low compression and pathetic retarded camshafts will not be efficient or have decent mpg. I would save the $ on converting it and run gas. A modern fuel injected engine or building a purpose built ethanol engine with 12-15:1 compression and many other improvements, with that it is easy to get better mpg and power than a gas engine.
no
I would go with 10w40.
how do you know a 78 record is a first run
All of them. Some were carburated, some fuel injected. Just pick the right one.
The firing order for 78 Regal with a 305 v8 is 1-8-4-3-6-5-7-2. The number one cylinder is the front one on the drivers side.
Show diagram for Chevy 305 engine
The Chevrolet small block 400 will bolt in place of the 305 but be sure to use a 400 flywheel or flex plate. Do not use the 305 flywheel or flex plate on the 400.
I owned a 78 Monte Carlo with a stock 305 2 BBL carburetor. If I remember correctly, the HP was 145MPH.

Assuming you mean 12 volts, then you cannot run any 78 Amp fans. Unless your fans run at 0.38 volts, there is no way to draw 78 amps from 30 watts.
no it almost 2 inches wider
it should be any 4 bolt main small block, like a 305 350 383 400 327 you could even upgrade to a big block, but you may run into some trouble with engine mounts.
