datASSun Posted October 20, 2014 Share Posted October 20, 2014 I'd love some 243's if I can find them. Just trying my best not to deal with the usual LS1tech member.. that always seems to be a ass beat. I've got a 5.3 with a cam and ls1 intake manifold. Found some 241's local but not sure how they will do on my stock bottom end 5.3 as far as compression goes. Quote Link to comment Share on other sites More sharing options...
