Thread: 454 500hp!!!!!!

Tweet

To get 500hp out of an 80s 454 truck engine is going to cost you way more than if you just buy a GM crate engine with 500hp to start with.

But if you have more cash than you know what to do with go for it. The first thing you'll need to do is throw those heads away or save them for boat anchors. Get yourself some good aftermarket heads. Get a complete engine rebuld kit with all forged parts and some high compression pistons. Find a good machine shop and get building.

i do not want to plug my shop well just a wee bit i know i can get you more bang for the buck over a crate engine anyday like others have said if you do not build engines or know what to look for then your just throwing good money away most guys for street use will not know it whey have 420hp or 500 if it bit them in the ass for street use you build for off idle use and max tq i would take TQ over hp and day hp is just for braging rigths i work thru many cams with a dyno soft ware and years of what i know what just will not work stock rods stock crank iron or steel and a hyper or forged will work
