Have a 1985 22RE that has about 9K on it with a mid range LC cam and header kit. I bought the truck built, and have never owned a 22 RE before. I have one question. While the engine has good low end for a 4 cylinder it does not like to rev at all. Makes allot of noise above 3000 rpm, and quits pulling at around 4500. She is all done at 5000. The stock redline was 5600. Is this normal for 22 RE's? It runs fine other than that. Just loud.......has stock exhaust, and good muffler, just loud and does not like to rev. Thanks.
