How many of you actually raced someone with your FWD HT4100?
My dad raced a mustang V6 and beat it, and he raced a NICE looking bmw 318ti and beat that too and that guy had a 5spd.
Once i start officially driving by myself, i will race my dads caddy and we'll see whos caddy is faster, my car has lots of engine mods! I have MSD EVERYTHING!!

The HT4100 isn't that slow in the FWD devilles, my dads caddy is figgin quick of the line, we easily passed an escalade on the highway and he was doin atleast 160km/h, the speed limiter doesn't work on my dads car, it does not slow down at all on its own. The 4100 sounds pretty damn sweet isn't all that slow.

What do you mean by that engine is too fragile, its a typical V8. If it is maintained properly, you shouldn't have a problem. If we too this car on a long Hot Summer day 5 hour uphill trip, this engine is flawless. I changed the spark plugs, wires, cap, and rotor on my dads car yesterday, last time plugs were changed was 8 years ago. I took them out, they looked like new. I changed mine also and they were completely black and my car has 94,000miles. My dads car has almost 200,000 miles on the engine and tranny.

Did your dad own the car from brand new? How many miles have you put on your Deville? If your dads car was previously owned how many miles did he put on it?

My dad is the second owner of his cadillac. He purchased it in 1997 with 95,000 miles, and it currently has 176,000 miles on it. The 4.1 has never been a problem, and always had regular maintenance. I haven't driven my car much, it isn't finished. I drove it to the shop and back a couple times. I still have to get my actual license to be able to drive by myself. I just drive my dads car for now. My car needs paintjob, and headliner. That will all be done in the summer when warm. My paintjob requires 3 coats of clear, metal flakes buid up alot.

That is a lot of miles, it proves what I always thought that the HT4100 engine is a pretty good engine. Do you know if that engine on your dads car was ever replaced before he got the car? The replacement HT4100 have improved gaskets and bearings, so that is why I am asking.

Still a motor with 176,000 miles (especially the HT4100) should not be raced, or held at high rpm for long periods of time, something is bound to fail with that kind of stress.

The engine is factory, plus my dad is friends with the x-owner, and we have all of the service papers. We took this car on 4 different hot summer trips, and they were all long 5 hour uphill trips. The spark plugs were 8 years old wen i pulled them yesterday and they looked brand new, mine were black. This engine is very healthy, but has noisy lifters, mine also has louder noisy lifters. They knock wen warm, i put a stethoscope on the rocker arm bolt and it sounded like someone was smashinig the engine with a hammer at a steady beat. But it made that noise ever since purchase.

I thought the 4.1 was the disgrace of Cadillac?
In the Classic groups we rather ignore that engine! As far as I know it's a POC if you look at it in terms of reliability.

1985 Cadillac Fleetwood (FWD): 3364 lbs
0-60: 11.7
1/4 mile: 18.2

1986 Cadillac Deville Touring Sedan: 3298 lbs
0-60: 12.0
1/4 mile: 18.6

1986 Cadillac Seville: 3371 lbs
0-60: 11.7
1/4 mile: 18.2

1985: 125 hp @ 4200rpm & 190 lb/ft @ 2200 rpm
1986: 130 hp @ 4200rpm & 200 lb/ft @ 2200 rpm

It wasn't a disgrace to cadillac at the time it was built. Cadillac needed to improve its MPG on all its cars so they used the 4100, and as a result the engine delivered the gas mileage the government and consumers wanted at the time. As I have said before, the engine wasn't bad it just requires you to keep up on maintainance.

It seems like a rather fragile, high maintenance motor, in comparison to the good old cast iron block '70s monsters

You are absolutely right, but the big cast iron block motors guzzled a lot of gas, which was what Cadillac in the early 80s did not want. By the way the chrome valve covers are really cool, my Grandma's 82 Seville has them.

The HT4100 engine is a very smooth engine so at least it was refined which went well with Cadillacs image.

Yeah, it was a very smooth motor, and quite advanced for its time. I always liked how they called their EFI "Digital Fuel Injection" :) Thats something Cadillac has always done, made a simple name or acronym very complicated sounding! And I have always liked that :D

Yeah;)

There's nothing wrong with the HT4100, it's just a sucky Cadillac engine. It was rushed into production after the COLLASAL failure of the V8-6-4. It clearly was never meant to be a Cadillac engine, and it wasn't until the Cadillac line got smaller in '86 that it was able to be a...decent engine. Thank god for the 4.9 and the N*:sneaky:

Believe me rick, i know almost every little thing about the 4100, i've been searching these engines for almost 2 years and finally got all of my questions answered. There is nothing worng with this engine, all you have to do is read the labels. My dads 4100 has almost 170,000 miles on the original everything engine and tranny. And he doesn't usually drive it soft, but doesn't sqeal tires upon take off. The 4100 is pretty quick in the FWD uni-body cars. I also installed MSD EVERYTHING on my 4.1, very big difference in power when we took my car for a drive. The 4100 also was an experimental engine and shares almost the same block as a corvette.

WTF?!?!?!?!
Give Me evidence please!


Even in the 3300lb "lightweight" 1985-86 devilles the HT4100 is a dog...noone would call a 11.7 0-60 fast.
Have you ever driven a 4.9 deVille? Thats a whole 3.5 seconds quicker to 60!
