Although I own a SB on "juice", I will admit that THE Boss Hoss that made me own one was a big block at the Spearfish display 4 years ago. Once the dealer lit it up, I had to have one :lol:
Honestly though, if I was going to go for bragging rights, sound, power and attitude, I'd take the difference in $$$$ between yours and a big block, and invest it in your small block.
Heads, pistons, cam, headers and you will out perform and outsound any 502......next time you're at a BH get together, look for any "built" small block and tell me it doesn't sound like a fuel or alcohol car :lol: 8)
For $20,000, you can buy an all aluminum small block with well over 600hp.......and be 200# LIGHTER than your stock small block.
Just my opinion.........
