408 vs 600 stroker

Budget is not a concern. Idk I just want something fun. But I was leaning more towards a 408. Do u guys see any problems with a 408 supercharged

Excellent choice! I've done a few 318 strokers with Prochargers sc-1, water injection and pump gas...mild combo's are 650HP and more cylinder head and cam will make 730HP while staying streetable.
I like the 650HP version as it's easier on the stock block over time...
