Thank you Titan, so meaning to say that i can use the na rb30 block which has single cam? sorry for the question because i need straight answer. thank you again to all.

can i use rb30 N/A block? will it be the same as the turbo rb30 block? or there is only 1 rb30 type? the N/A? thank you, because i dont know much about rb30 and im planning to change the 25 block to 30 block and stay with my 25 head series 2.
