I just finished up dyno testing my 433 Lincoln Y block that is going in a 56 Mercury replica of the Thumper car that ran on Daytona Beach in 1956.

Engine specs are 4.1 x 4.1 433 cu in 9.25 compression 240@50 cam with .525 lift. For testing I used an adapted Victor Jr intake from a scrub and a 750 Holley. When it goes in the car it will get a M-335 2x4 intake. It should move that Merc along smartly.
