Forgive me my Mopar brothers. I have sinned

My '75 wrecker has an FE in it, not even sure which one, lol! Like Rusty said, "452" on frt of block, but..
I had a 390 w/a busted rod given to Me(long before I got the wrecker), looked OK otherwise, crank & block had no real damage. Couldn't give it away, even to a Guy w/a short-bed version of the OP's era, who had a 360 in it runnin' high 13's...
Ended up keepin' the heads, valvetrain, covers & dizzy...gave the rest to My Bud who did a bunch of scrappin'....
