Thx Mr Tim San !!!
Perusing this thread (& others) 'cause I know 'zip' about the B & RB platforms...
By way of ... mmmm ... context, I spent 2k$ on a 273 in '69,
wiped the floor against some Big Block builds, ...
That being said,
I also had My arse "handed to Me on a platter " ( read 4+ car length losses) by
383 'turd engine' powered platforms numerous times.
Apologies to the O/P,
