408 SB versus BB 541

Was taking a break from working on my Dart which is almost finished. Found a 440/541 stroker kit .Kept looking at parts, heads, oil systems, cams, carbs, headers which i will probably have custom made etc. etc. I know that the entire drivetrain and suspension will have to be maxed but I was going to do it anyway. I could be wrong but it looks like the 408 is the same money as the 541 . A “friend “ who has a 200 mph ten second Porsche has been making negative comments about my Dart. I would love to smoke his ***(only in the quarter, there’s no way I’m going that fast.
Your impressions??
