I have a TH4oo transmission out of a ‘72 Riviera that was rebuilt with the intention of living behind a 450HP 455 in a 4500lb Riviera. Performance rebuild done by Ed Dedura in CT who has done a number of race transmissions for Northeast guys. The pump was converted to a VP or Switch Pitch pump (depending on the nomenclature you use). Transmission has never been installed. I also have a Switch Pitch/VP converter built by Jim Weise at Trishield Performance. It’s new in the box, never installed. $1,000 for both. Located NW of Philly 18966 zip.
