Anything you like as long as one of them is greater than or equal to sqrt(409). Let L be any length greater than sqrt(409) feet and let B = 409/L feet Then L*B = L*(409/L) = 409 sq feet.

These totals do not include trucksThe 409 was a 348 bored .187 over. The 348 was 4.125 x 3.25. The 409 was 4.312 x 3.25
I can find no evidence the 409 was installed in any Chevy or GMC truck. The 348 was used in Chevy trucks and the look almost identical to a 409. But, I cannot say positive that Chevy never put one in a truck. Further research is required to give a definitive answer.
