I used to have a Ls2 in my car (243 cylinder heads) now i have a 402 CI stroker with ported heads.
My issue is that the adaptor i was using for my FD gauge on the 243 heads doesn't fit the LS3's 12mm x 1.5 threaded holes. What are guys that have LS3 heads i.e.; 821, 823 and 5364s using to keep their OEM temperature gages working Temp sensor wise?
