    I've been wanting to detail my engine for a while now but I've always wondered what exactly needs to be covered so it doesn't get wet, all I know to cover is the alternator, ac compressor connection [the one right on top of the compressor], blower motor, battery i guess and thats all I know for...

    RWD 19xx-1984 DeVille and Fleetwood,1985-1996 Flee
    Hey all, This is in regards to my 1986 FWB 307. My gasket for the top of the carb (airhorn) seems to be soaked (probably gasoline)..nothing that is dripping from it, but just soggy..easily tear-able. I tightened up the screws for the top of the carb (airhorn), which were loose. I want to...

    Informal Lounge, Introductions, General Discussion
    I know, I know, not an olds forum etc. etc. but someone's got to know. Maybe Chad? It's under the dashboard, so says my dad. How difficult would this be to do on our own?

    RWD 19xx-1984 DeVille and Fleetwood,1985-1996 Flee
    Anyone know where I can purchase one for the 307 on my 89 Brougham? It seems GM has discontinued this part. I can get one from a junk yard down the road but would rather buy new if possible. The GM part number is 17111104 I believe.

    I have a 5 year old son that never ceases to amaze me with the things he says and the questions he has for me. I read him a book and put him to bed tonight and he says to me: "Dad? What happens when we run out of years?" I say, "What do you mean?" He says, "What happens after we run out of...
  15. Olds 307 Heater lines.

    5.0 and 5.7
    Hi all, I'm currently a bit confused when hooking up all my coolant lines. It seems like I'm left with one extra. I found this picture online but can't figure out where the hoses are routing to. I'm talking about the two fittings that come out of the passenger's side of the engine. One (boxed...
  16. Car doesn't turn off. (Olds 307)

    5.0 and 5.7
    Hello all, I put an Olds 307 in my '82 Deville. I'm almost finished with the swap and today when I started it up the car didn't turn off. This was the first time I ran it with fuel lines to the carb so it didn't stop running from being deprived of fuel. I have taken out the computer. What...
  17. Anyone looking for a Olds 350 (72-73, "8" heads) for a swap?

    5.0 and 5.7
    A friend of mine is parting out a 83 Cutlass with a 72-73 350 with "8" heads. This is a great swap for anyone with a 307. I did a swap in my 85 307 Cutlass and it was very very rewarding. mpg was almost no change, and I can't imagine in the heavy boat Broughams that it would even possibly...
  18. 4.1 to Olds 403 swap

    HT4100 4.1, 4.5, 4.9
    Hope I got this in the right place. I hope to possibly buy a clean '84 coupe, which has the HT4100. The current engine runs great, but I find myself wondering about possible swaps. Would a 403 Olds engine fit without too much hassle? The Olds seems like a natural fit because the 307 was...

    RWD 19xx-1984 DeVille and Fleetwood,1985-1996 Flee
    I may be getting a 1972 Oldsmobile 350 Rocket Motor to rebuild for my engine class in college. When I am done with the motor, I wouldn't mind putting it in my 1984 Cadillac Coupe DeVille. Since the Olds Diesel was an option, shouldn't the Olds 350 Gasoline motor bolt right in? (I would need...
