Howdy guys! I have a 97 Tahoe, Wynjammer sc, dual Flowmasters and 1.7rr. I'm considering a ls1 swap as I've gone through 3 intake manifold seals, always out of warranty of course. It's leaking again and I've got 97,500+ miles on it so I was thinking about alternatives. Another full size forum directed me here for the information. This looks like a lively place. Matt
