  1. All of you gentlemen are correct. The LD37 or 275hp NS has a milder cam. it also has an 3:11 gear ratio. the LD38 300hp NS has an more aggressive cam and fuel/air ratio curve to match. The 3:71 gear ratio ( I think? ) snaps through the quarter faster because of that upper rpm band of 4500 plus, all the way to 6000rpm. I have experimented with flipping out computers. A base with a PCM out of the same year DTS. As I suspected and previously noted on here. The fuel gets pretty rich under WOT. and with the difference in tranny gearing the PCM is in LIMP mode from the get go. I have been all over the web, net, and cosmos looking for someone who does flashing of the PCM. That is the answer to your problem my friend. They are out there you just have to find them. I have conferenced called ADS Superchips, Hypertech, and Boss performance. They have all said the same thing. There is no market for this ECU program. So it has to be done by a special programmer. This issue is hot in the world of the wreath. I am looking for other undercover Hi-Po Cadillac freaks to help me out. "Tiny"
  2. Man, that is one hateful Caddy, If I had the money i would trade my S55 AMG in for one of those heat seekers. I am proud that Cadillac has had enough crap with the Europeans, and Japanese, when it comes to power, prestige, and perfection.
  3. Yes i can my friend (www.woodview.com), an excellent assortment of woodgrain goodies for your El Dawg. I recently bought a 40 piece set of exactly matching wood interior for just a tad over $170 beans. It is the truth, and adds that sexiness that only Cadillac can only deliver. Tiny
  4. On my "04" I actually experimented with some tuner exhaust and actually produced a "deep mellow yacht" style of sound. The days of the 70's as my Pop's would say. 3" pipe back from the converter (high flow) ofcourse. Beautiful idle, until youcrack the throttle from the light. The Crown Vic, Lincoln, and Mercury boys are saying WTF! No glasspacks here gentlemen. Now its on to flash that OBD II ECU to get my top end right and fuel curve cleaned up.
  5. All of these inputs on this forum is good information. I have done research on this subject. Every ( GM ) technician I have spoken to, which has been plenty has advised against anything over 10w-30. If you look in your manual at the oil chart the 5w-30 is what recommended along with 10w-30 but at a smaller temperature range ofcourse. My good friend and neighbor is an Master technician at the local dealership ( 26 years ). He explained this to me. Anything under 75,000 miles 5w-30 is a good standard as long as you have the 3 to 5,000 mile oil change ritual going. But after 75,000 miles tolerances loosen up, inner wear / friction takes center stage. 10w-30 adds that viscosity protection. But all in all Lucas is a sure fire bet. With my Cadillacs I actually use 1.5 quarts because if you read the back of the bottle it says 1qt. for ever 4 qts. of oil. At 7.5 qts. of total capacity 1.5 qts. of lucas is just right for me. Short story.........Had a 1991 Lincoln Town Car 4.6 SOHC setup bought it with 178,000 for $1,000 dollars. 5 years later and 333,000 miles !!! , it finally shot a rod. From day one 15w-50 synthetic mobil 1 / lucas car ran itself to death!!!
  6. NO As my counterpart explained directly in two letter form, the motor is shot. The block is three pieces of aluminum. These motors are notorious for stripping head bolts. Which, therefore comma leads to ala cream dele northstar (blown head gasket). If you read the manual on both generations they go through many safety characteristics before giving up the ghost. Shutting down the A/C , going in to power limp mode, specific cylinders cooling the heads and block, rpm default mode etc. After all that there is no saving it. Put it on ebay for a nostalgic boat anchor.
  7. Sounds good Bruce, I bet those dual mufflers give her a nice throaty growl. The OEM mufflers in the tail contain a massive amount of backpressure and great V8 sound. I have been doing some research and as of yet they do not make a power programmer 3 for either generation of Northstar, or Oldsmobile's Shortstar. Your base model "Deville, Seville, or Eldog", (LD37) will drop the fuel pump anywhere around 125-130 mph. I don't know if that is mph controlled or RPM driven? But on the other hand your DTS, STS, and ETC will walk the dog on up the scale. I have had my 97 STS up to 148 mph on stock skins. I have also read that the (LD38) motors will push on up and over 150 mph. With the 3.79 tranny ratio I can see the hole shot advantage as well versus the shorter 3.11 in the base models. Not to mention the 20-25 hp difference. My next mission is to do a dash conversion, billet / mesh grille, DTS low swept tail, and Chip Foose wheel package on my base model. More performance mods are in the works but have to continue the research as I go. "Tiny" Crawford
  8. A good reference of tire size for your car is victoriatiretire.com, these guys are pretty methodical. The next best thing than asking the OEM guys themselves. But IMO 245/45/16 is a standard meaty approach. Once you get past 50 series you are starting to stretch the envelope in height and width. You don't want to start throwing your speedo off.

  9. Furthermore does anyone know about some computer upgrades with the OBD II ECM, or a possible power programmer III, ADS Superchips, or Hypertech? Could some help me out. "Tiny" Crawford
  10. I wanted to ask the public there opinions of aftermarket exhaust for Cadillacs? I have owned six Caddy's and have did exhaust tuning to five of them. Everything from a 1950 61 series sedan, to a 99 Escalade, to a 04 Deville. What I have noticed is that #1 the competition is stiff and expensive. #2 the sound performance is similar, except for "BILLY BOAT". But in the past being a sound mechanic and military trained certified welder, I have found out through other various sources and vendors you can create a pretty darn sounding, looking, and performing combination. Consider paying $800-$1000 bones for a your local heavy weights, or going through google you will be ammazed at what is really out there for these cars. For example I went to 3 inch stainless steel piping properly bent ofcourse from the cat back. I bought 2 (two) chamber stainless steel mufflers from a company called Roku Performance that replaced the standard OEM bricks. On the Dyno factory no mods, the car posted 212.67 hp net and with the change up 226.79 hp net three pass before and after that was the average. My 02 Deville with a Corsa set up was 214.44 hp net before and only 220.21 hp net after. Any thoughts on this subject? "Tiny" Crawford
