What would you build if limited to 372ci - with boost as an option

Please tell me about the class and what is the current record?
Well the class is B/CGALT = b engine size (373-439.99)/ classic gas altered. This is for rookie and shakedown runs. Then add boost.

B/CGALT - 254.100 mph

Add boost

B/CBGALT - 243.015mph

C/CBGALT - 224.331mph this is the smaller engine displacement (306-372.99) and the reason for this discussion.
