Hello All new guy here with a question. I am going to be building my first met and was curious which intake I need for the hasegawa F-16 CJ. I'm building it a Block 52 with LS engine now the GE. So I would need the NSI right??? I have heard the use both but want to be sure.

Block 52 uses Pratt & Whitney F100-PW-229, not GE. "Big mouth" intake can be found on GE engine blocks 30+, all PW-equipped versions still use the original smaller intake. I mean I've read PW engines would work perfectly fine with big mouth intake, but I don't know if any Vipers have actally been built in such a configuration.
