What would it take to make 1.44 lbs-ft per cid ?

The MT 408 build isn’t exactly what I’d consider super budget friendly with a solid roller and TF heads.

Somewhat comparable build……
410”, 10:1, bowl blended RPM heads, easy on parts .600 lift roller, Victor 340, street Q 850 carb.

524tq@4700/538hp@5900.
Start of pull: 3900 = 496tq
End of pull: 6400 = 531hp
