did a 400/451, CNC ported iron heads, Comp custom ground Monster Motor cam, Lightened crank and balanced. Rapped like a hooker on meth but wheelspin was just too much to handle without tubbing it, and doing all the traction mods to boot. IMHO you can stroke a 360 and get big cubes or just use the money to blow a LA and not have to worry about 'frame' twist, and tubbing as a turbo comes on soft. Also turbos dont need expensive headers, just some flipped Magnums and lots of plumbing. Most competitive "street" drag cars are blown nowadays if they are grudge match cars.
If you do choose to B/RB it, just get to the point fast: Youll need to lose the inner fenders and go J-Bars so you can have some exhaust options. SO much easier without that hinderance. The Passenger side is not a problem, almost a drop in with stock headers (watch the idler arm clearance) driver side is a mess with the steering bar and pitman arm. Pro-Parts to the rescue...1 tube needs to be modded on either side but they are fenderwell so youll be hacking yours anyway, hence the delete advice. Tie the shock mounts to the J-Bar
