Picked up one of my dream cars a few years ago. It’s my cousins old 84 Monte ss. In the late 90s he swapped a stock 454 from my dads old truck and it sounded awesome, but couldn’t outrun a mini van. Got the car running and updated a few things like battery, tires, etc just to get it running. I fell into a 90s gen V 454 and decide to just build it then swap it out when I’m done. Goal was about 500hp so I did new rods, 9.5:1 pistons, decent flat tappet cam, 781 heads, headers, intake etc. Super excited for my first big block build. And then it ate the cam on start up.
