New to all this an not sure if this will work but it's worth a shot but I've recently gotten done building my new small block 350 .40 for my 97 k1500 I've gotten the short block and did the rest myself by the book got it in the pickup and carefully drove it 300 miles before the camshaft sensor flew a code and a misfire happened by the plug wire burning. Fixed them both now its running a rough idle and seems to have a light knock (which i hate to say) I've tried another new sensor. MAF sensor, plugs and plug wires and i just seem to be lost on the whole thing. Again my sure if this will work anything but it's worth a shot thanks!
