Hello,

I have a 1976 CJ7 Levi edition Jeep with the 304 V8 engine. It is in
need of a overhall. The body needs to be totally sand blasted and
repainted and I want to replace the engine. I am thinking of putting a
remanufactured one in. The one I have uses 1 qt. every other tank
(about 110,000 miles.) There is a posting from 1996 that I placed on
this newsgroup which I found by doing a Google newsgroup search. I have
yet to do any of the repairs stated in that post except for fixing the
full tank leak.
This Jeep is old enough that I don't need to have any more smog checks
done. What does this mean in terms of what I can remove off of this
engine in the way of smog equipment? And how much horsepower increase
will I get if any? I live in California.
Also is the body just bolted to the frame or is it welded in places? I
wanted to take the entire body off and repaint both sides inside and
out.
Reading on off-road.com it looks like that not all 304s have the same
horse power rating. What is the reason for this?

Thanks,

John

 

Hi John,
Your engine has less horsepower than the same displacement in the
sixties because we had a cheap way to build octane with lead. To be able
to burn cleanly the lower octane gasoline for the new SMOG regulations
meant we had to lower compression, cam duration, lift, and valve size,
along with the it's cross flow design taking away the supercharging ram
effect. virtually cutting the power and mileage in half:

four hundred cubic inch bolts right in, you may recognize it by that
number under the drivers side mount:

The body is bolted on. It may feel like its welded on when you start
taking out those 28 year old body mount bolts. If you find it welded
anywhere, it certainly wasn't stock.

>>The one I have uses 1 qt. every other tank (about 110,000 miles.)

You get 55,000 miles per tank? ;-)
