no
Yes it will fit. This distributor will fit all small block and big block Chevrolet engines.
1,8,4,3,6,5,7,2 all small block and big block firing patterns are 1,8,4,3,6,5,7,2 for Chevy
The distributor can be turned both ways. The rotor however, which I suspect you are asking about, turns clockwise on a small block V8.
No the distributor gear that is on the end of the distributor is to small for the big block cam shaft.
Cranksaft turns twice for 1 distributor rotation.
That would be a big block. If you are referring to the diesel engine, it is based on the Oldsmobile rocket block, and shares nothing with the engines usually referred to as big block or small block.
NO. Depends on the year. On the pre-fuel injected motors, all Chevy V-8 engines used the same distributor. Use some common sense, a 1968 distributor is not the same as a 1980, but you get the idea. Use one from the same era as your vehicle.
On a small block Chevy the distributor goes through a hole in the intake manifold. On a Pontiac the distributor goes behind the intake manifold.
Most SBC have a port next to the distributor.
It's usually on the rear rail under the distributor.
Right behind the distributor. It takes a special socket, too.
The firing order used on early (pre-Gen. III) small block and big block Chevy V8's is 1-8-4-3-6-5-7-2. hope it helps.
