409

Was removed from a 1964 409 425HP restored engine to install period correct 583 Heads My 1964 Impala SS 409 425HP Dual Quad recently rebuilt engine was built with 690 heads. To make the engine correct for 1964 I replaced the 690 heads with correct 583 heads. Finding the 583 heads was difficult...

Still looking for a 1960 Bel Air sports coupe if anyone knows of one that might be for sale. Nothing rusty, but would consider finishing a project if needed. This is a no post two door car. Prefer stock but would consider anything Any leads are appreciated. 60

Here are some of the 409’s at the 2023 Scottsdale auction.
