Most guys I knew, including myself, in the late 50's and early 60's dreamed of swapping a six for a big V8. I pulled a 216 out of a 48 Chevy business coupe and dropped a Olds Rocket V8 in there. I ran out of money before I finished and had to sell it. I had a 51 AD later in 1966 and would have gone the V8 route had I the money. That's why I put the 350 crate in my current 51.
...still a kid I guess. While I love the sound of a six with split manifold I love the rumble of my V8 more. To each his own. Nothing is better just different.
