Why was the 3.4 so under-utilized?

[slick]

There is a Regal With a Superchager in th J/y thats lit on fire... it was an old ladys car... i could tell by the stuff that was in the interior.... so no modding there....i wonder what happend

 

As said above, either dried out o-rings(which happens as o-rings get older) or really really leaky valve cover gaskets(which again, happens, and i'm sure she wasn't under the hood to see if there were leaky gaskets).

The LQ1 is a WIDE ass motor with those DOHC heads on it, I would bet it's probably as wide as an assembled V8 when all is said and done.

 

It IS wider and heavier than a Cadillac 4.9 and damn near as long.

 

A little O/T but GM built 10 Luminas around 1990 with Cad 4.9's in them as test mules. They reportedly handled and performed very nicely but Cadillac didn't want to share an engine with the other GM lines.

Cadillac should have used the Twin Dual Cam as a base motor then, and have the 4.9 a higher engine option.

Why? The 4.9 sucks. It's performance is lackluster, and with the amount of them I see in the junkyard, I can't expect them to be that great of motors to begin with.

Other than the LSX engines, does Cadillac share any motors with the rest of GM?

Well the Buick Lucerne now has a northstar.. but I'm not sure if it's exaclty the same model engine as in any Caddys...

Sorry for the hijack but I have to ...........

 

 

I see a lot of 4.9's in the junkyard too, most I see have a couple hundred thousand miles or more on them and the cars they were in were driven into the ground or totalled. When I went shopping for mine for the swap (that hasn't happened yet ) I had a Hell of a time finding one with less than 150 to 200,000 on it. I finally found a cream puff '95 DeVille with 50,000 on it that had been t-boned. However, your bad opinion of them is not without good foundation. They definitely had their problems, especially the first 4100s and 4.1's, they were the second worst V-8 Gm ever built, the overall worst was the Chevy V-8 built from 1917-1919. The 4.5's were a little better and the early 4.9's a little better than that. The '93-'95s had most of the bugs worked out of them but by then the Northstar was in production and who cared about the 4.9? According to a couple of my friend's that were mechanics for GM dealerships before opening their own shops the Northstar is not without it's own problems. The later 4.9's were good dependable engines IF you did the proper cooling system maintenance and performed very well for what they were originally designed for, hauling around big heavy barges quietly and dependably. Placed in a lighter platform they are no race car but can still be a lot of fun and with a good exhaust system sound really sweet. Would I recommend everybody run out and snag a 4.9 for their car in place of their V-6 of choice? No, but if you have a good W-body or Fiero in need of a motor and stumble across a deal on a '93-'95 it does make a pretty slick swap. Just be aware there is NO aftermarket and except for a little tuning, exhaust and a converter and gear swap for the transaxle there isn't much you can do to mod one. But if you just want a driver with decent performance a nice deep V-8 rumble and something that is smooth and torquey give it a look. BTW the '95 is the best year and has the best exhaust manifolds by far. I had thought about dropping mne in my LeSabre instead of a W-body IF the 3.8 ever died but at 192K it's still running strong and shows no signs of packing it in anytime soon.

I figured they couldn't be that terrible, considering the ASG 5.0 is based off of it. Speaking of ASG. I haven't heard shit from that company in a long time. Hell, last time I heard anything about that motor at all is when that mistake of an Integra.. er.. Z34 got one swapped in.
