Clockwise.
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
Yes it will fit. This distributor will fit all small block and big block Chevrolet engines.
Clockwise.
No the distributor gear that is on the end of the distributor is to small for the big block cam shaft.
305 is the same distributor as a 350 will even fit some big block chevy's.
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.
Actually the complete distributor will fit from the small block to the big block.
Some do, some don't. The distributor, starter and alternator fit, the water pump does not. The mounting brackets are all different.
all chevy V8 are the same 18436572 in a clockwise distributor rotation when viewed from the top.
Loosen the distributor, and turn it counter clockwise. This should be done with a light in measurable amounts.

The 400 Chevy is a small block engine. The 400 BIG BLOCK Chevy does not exist! 402 big block Chevy does. it seems in the early 70s Chevy put 402s in their pick ups and they had 400 badges. this opened the can of worms known as the non-existant big block 400.
