I have a 1973 cheyenne super. Engine code LF8.Does anybody know the specs on this engine? And where can I go to look up all the info on this truck?Thanx.
LF8 is a 454 7.4L. I thought that it was only 77, 78 and 79. But I could be wrong. I have a 1978 C30 1 Ton with that engine. I'm Not sure what specs your looking for?
