Sell me on an LSX I have a 1986 Monte Carlo SS that is bone stock. I am starting to buy parts for a pretty thourough resto on the car. I will probably do all that I can without taking the body off the frame. I have been thinking that I would use some LSx variant, but lately I've been eyeing the 454 sitting in the corner of my garage. It is just a core that would need everything. So lets just say that I could stroke the big block to a 496 and build w/ aluminum heads, intake, etc, to lose weight, what advantages would a LSX have over the big block. I know that some of you probably own or have owned both.
yeah, the big block certainly will produce a higher peak hp, but the ls1 will be lighter, more driveable, able to pass emissions, have a flatter power curve, and is just better engineered in general.

Thanks for the input. The car will be a street car maybe even daily driver in the summer. Is a big block with aluminum heasds, intake, water pump, etc alot heavier than an Lq9?
The way I see it LSx plusses are:
Great factory components
Efficient EFI comes factory
Very upgradeable
Downsides:
More modifications to car to make work.
Can't use factory accesories.
Aftermarket parts are $$$$
It looks like if I want to do a budget Lsx it definitely needs to use as many factory parts as possible.

Real Gas milage and ***** out tourque.
Real fast revving.
you can start it on cold weather..
never worry about tune ups and adjusting timing or carb.
100,000 miles on spark plugs.
easy to diagnose.
Way lighter..
Burns sooooooo much cleaner.
hardly no one has one..
car show onlookers dont know what they are...
set up for unleaded gas..
dont leak oil nearly as bad.
can make great hp and torque with just heads and cam.
6 bolt main caps..
run cooler than the BB.
your SS will carve the corners much more like a NASCAR.
auto 4l60e can shift better than most humans.
great stock ignition system.
starts every time.
you will install it and turn the key and it will start the first time, AND RUN GREAT!!
will idle like a Caddy compaired to the BB.
can find parts like their going out of stiyle.
if you change your build direction you will have a better chance of selling the LXS motor.
Gas is probably going to be 3 bucks a gal. next summer.
and LSXs dont make as nice of boat anchor as BBs do..
That is a start. Hope it helps!!!! BUY ONE AND YOU WILL SEE WHAT WE MEAN....

Yes, and its going to cost a bunch to completly build a big block with alu heads. take a ls1 or lq4 and put a decent cam,springs, push rod in with good converter and fly, for cheap.

I too ponder the question of what to do with my 87ss, when the 305 was done. I gave it several considerations. One it'll have Classic Tags". Yes, it limits milage. But that doesn't matter to me. The advantage here in PA, no emissions. I considered either a 383 stroker, which makes plenty of horse and fits right in. Or the LS1. I figured the LS1 was the route if converting, why do all the work (and it doesn't just fit right in) and put in another iron motor ? I got lucky and found an 06 crate motor that did a season in a road racing vette. So, that's what I went with. It's on a carb and MSD, with a fresh 200r4. It really depends on what your looking for. An aluminum head 383 would be just as potent and considerably less work, as it'll fit right in. You can actually buy parts,Like headers. A/c fit's right on etc... Depends on what you want.

It's a pretty controversial question to ask here.
