340 Intake

1971 was first year for TQ and the TQ intake. '71 and '72 are IMHO the best years for the TQ cast intake. The later years had the 'bolt' in the plenum floors. Removing that and pluging with JB weld or welding it closed then it would be equal. Have to know what you are doing to weld cast iron..be careful. Good luck and as always...give us a progress report.
