That's an LS-4.
Depending on the blocks casting date,either 1973 454/240Hp or 1974 454/245Hp for TRUCK applications.

If the last 3 nbrs on the casting are 289 they make great builder motors. Thick wall casting can go 125 over bore.
Money wise, no real collector value. Just good iron. 350-500 maybe.
