Crazy_Jake Posted October 6, 2013 Report Share Posted October 6, 2013 So I've got the L37 or 'High Output" Northstar in my '94 Seville STS. Recently discovered that the ONLY difference in the two motors (the LD8 in the SLS models) is that the L37 has a more aggressive cam profile. And apparently, it only makes that extra 30hp above 5000 rpm, sacrificing lower band torque/hp. Don't know about the rest of you folks, but I don't like to drive my 20 year old car that aggressively. Seems like I'd rather have the low end power. I had a '97 Deville that seemed much faster than my STS and it always made me wonder why. Although after I get this current rich fuel problem I'm having all sorted out I may have a different opinion. Just curious what the rest of you think about this. P.S. Notice I said "motors". STS has a stiffer suspension that is electronically controlled. Can't remember what they call it (the suspension). Link to comment Share on other sites More sharing options...
rockfangd Posted October 6, 2013 Report Share Posted October 6, 2013 Note the transmission is different also. I prefer the 275 HP one over the 300HP one. I also find that the 275 has more low end torque. as for driving a 20 year old car aggressively that can be a good thing. I sure do and all of mine love it GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...

Just makes me nervous for some reason, like I'm going to throw a rod, lean out under full throttle and burn/blow something up, kill tranny, etc. Link to comment Share on other sites More sharing options...

It takes alot today to blow things, especially Cadillacs. If it is broken in and runs good. I drive it like I stole it GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
