If N/A 1 3/4 or 1 7/8 will be fine. Personally 1 7/8 is great for blown applications and 1 3/4 for 302 cubic in n/a
Well that's exactly the answer I was looking for. So because I plan to go turbo in a year or so but will be n/a for now the 1 7/8 won't be over kill or cost me any power loss? as the 1 3/4 would be great for N/A regardless.
