360 vs 4.0



Frank
2-V 360s ( and 4-vs) I pulled were running junk yard dogs for daily driver Javelins, no 1/4 burners.  I agree, as I too have stated the 4.0 swap as "quick and easy". and for an 6cyl equipped AMC, this would be a excellent swap.

I'm comparing more with driving around, you guys are focusing more on
performance. I have noticed that the 360 revs a lot quicker than the 4.0L
-- that's the only drawback to using it for a tire burner. The stock EFI
isn't real responsive to flooring it right from the start -- there's 1/4
second lag in response. Take it a little easier -- don't slap the pedal
down but be a bit more controlled about it -- and it's not as noticeable.
I'm not sure if it's the EFI, the long stroke of the engine, or the auto
trans, actually. Can't tell. But there's a definite slight lag in mine.
Bear in mind I'm running a 4.6L stroker with a Renix system, so all that
has some impact. But running either stock 4.0L (88 Renix) or 4.6L (same
engine, bigger injectors and 258 crank/rods, dished 4.0L pistons) with a
stick and 3.31 gears, burning the tires off was easy -- with a one-legger
anyway. It would actually spin both tires for about a foot then the left
one would stop spinning. With the auto and !
3.55 limited slip, it will only burn the tires if there is something on
the road to let it slip a little first (water, sand, etc.). Kind of
disappointing, but then I've out run stock V-8s from a standing start.
What I think was a 305 Camaro (could have been a tired 350), and a Dodge
Ram w/360 (lifted with 30-32" tires though). That Ram guy was a little
miffed when he saw the 4.0L six (hadn't stroked it yet). 

For all out performance you can do so much more with a 360, that's true.
The 4.0L won't put out much more because it's already near its peak
efficiency, the 360 has LOTS of room for improvement. But if you just
want a bit more power, and thinking a stock 360 swap, the 4.0L EFI will
be a much better choice -- unless you plan on adding a lot more to the
360 later. If the car is to be a daily driver, I wouldn't even consider a
360. Parts aren't to hard to find, but gas might be!
