360 vs 4.0

I have installed many 2-v and 4-v 360s in Javelins, out of mid 70s AMCs, and have found that the 360 is a very good engine. I have burned the tire off of Javelins with these 2-v360s, and I will have to say, I have not found that to be true of a 4.0. I have Driven the 90s Jeeps and they do not pull like the 360. I would say the 4.0s are rated at what they are advertised at, I would say the 360s were under rated. The 4.0 is a great 6, and has more power then the other ( read earlier none FI 6s) AMC 6s. Like I said before, the CC American build would have been perfect for this. Show what the car does with its 199, put a 4.0 in, maybe build a 4.0, then go to the 360. You could of had a very good comparison on these engines.

Frank; I'm still not buying it. You stated that the
figures speak for them selves then go on to justify
the numbers with about a page of "explanations". No,
not gonna buy it.
The 360-4v, I've been around them all my life and I
like that combo. I see a lot of good performance when
they are in the AMX or Hornets (I know, AMC never made
that combo except for the odd ball special order) and
I don't see any comparable performance from the 4.o in
the later cars.
Now we are talking apples and oranges, I know. But for
the money saved by dropping in a 4.o over the 360 you
can do some decent upgrades to that 4.0 by going the
stroker route.
Years ago when I pulled the 304 from my Gremlin and
dropped in a 390-T10 combo a buddy had a a beater
American. I explained what I was doing, he helped me
wrench on the Econoline axle under the front, and the
next week he was dropping in a 360-auto with the stock
4V manifold and carb I gave him. With just bare bones
upgrades(dual exhaust with cut outs, a hot coil and
cheater slicks) he got the car into the 13s. This was
just all basic AMC stuff except the slicks and coil.
He proceeded to tear up the rear end and ended up
going to a Ford 9-inch. I lost track of him, but with
just a basic 360 he got that American going. Do you
really think a base 4.0 will get the car into the
13's, I don't.......Russ
