Hello All

Her we go again.
I'm looking for the NHRA guide that list Part # that can be used for SS Motors.
Example what Heads are legal for a 427/430 HP L88?
What after market head is legal?
What Block casting # are acceptible?
Can an after market block be used? Which ones?
What cranks are legal.
ect ect ect...
I'm sure there is a list of accepted parts some where on the web, or that can be bought from NHRA .
I'm just looking for something to read, about SS.
