68, to 73, point type. 74, to 89, HEI. After 89, first gen vortec. Chevy only made 3 special distributors, that I know of. The early dual point, with a second version with a mechanical tack drive, for Corvette. And in 69, in the DZ302's, and L-88's, and again in 70, in the LT-1's, LS-6, LS-7, and then 71, 72 73, in the L-46's, they used a special high performance with a more aggressive point cam. Other than that, they are all the same.....
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.
no
Cranksaft turns twice for 1 distributor rotation.
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.
It's usually on the rear rail under the distributor.
Most SBC have a port next to the distributor.
Right behind the distributor. It takes a special socket, too.
Actually the complete distributor will fit from the small block to the big block.
