Re: 1969 nova ss
That last tach picture looks like a 4500 yellow line, and a 5000 redline. If it is for a small block Nova, then that would be correct, right?

Re: 1969 nova ss
The yellow/orange shading starts 500 rpm's below the redline on all 3 tachs...kind of hard to see..but that's the way it works....
besides, who cares about redlines anyway...???   wilma

Re: 1969 nova ss
Wilma, redline tires are nice!!
 I read an old article from 1970 that talks about the L34 and L78 cars.. They stated the redline for the L78 was 5800 rpms.. Hey I guess it is all in the way you interpret it.. There is no doubt these engines can handle more rpms than advertised!! I just thought maybe the pictures would clarify things a bit...Rich......

Re: 1969 nova ss
What you might be referring to is the horsepower and torque specs for this engine....68-70 L78's were advertised at 375hp at 5600 rpm's..torque was 415lbs at 3600 rpm's...these numbers are a little conservative for what the engines actually produced...when this motor was introduced in 1965 it was rated at 425hp...but at a higher rpm(around 6300 I think) the rating was dropped in 1966 to 375..probably to help with the marketing of the new 427 engine or maybe to keep the insurance companies happy..who really knows..??
