hi i just recently bought a Chevy 454 big block engine in hopes of putting it into a 70 chevelle.
the guy i bought it from inform me that the engine came out of a mid 80's dually truck. Besides that i really don't know anything else about the engine, i have tried doing some research with the engine casting number but to no avail. On the actual block i noticed it had 7.4 liter. I was hoping if you guys would be kind enough to give me a little bit more information on the actual engine & maybe some advice on how i could transformed it from a low hp high torque engine to a respectable muscle car engine. The engine casting number i
believe is

140154451

Thank you for your time, your patience, and your informatio
