RE: 391 questions
By John - 05/03/2001 1:44:49 AM; IP 63.161.101.228
The heads are a bad choice for performance because of smaller valves and ports and also a larger combustion chamber. Some of the 391 blocks had the reinforced webs and some did not. If you run an auto distributor you will need a bushing. A 391 truck motor is externally balanced. A 391 truck block can a lot of the time be punched out to 428 but would need sonic tested first. This would make a cheap 428CJ block if its is one with the reinforced webs and you have a 428 crankshaft. One to look for D3TE or D4TE I hope I helped you. John
