Cadillac 429 Engine Information Request
I have the opportunity to obtain a vehicle with a Cadillac 429 engine
in it. I know next to nothing about these engines other than they were made from '64-'67 (I think). Therefore I have some questions: 1) Was the design of this engine 'good' or did it have problems? 2) Was it considered a 'performance' engine or just 'run of the mill'? 3) Are there any sources for aftermarket performance parts? 4) What are its stock HP, torque, etc. specifications? Thanks! |

I had a couple of them. One of them overheated terribly once when the water pump bearing wore out. I'm convinced that this may have caused a piston to break. The rebuild was very expensive.

It had a lot of power and torque, and the integral cooling system for the heads was a good idea. The two middle cylinders on each bank were siamesed, and tended to build up a lot of heat. When tuned up properly with a strong transmission behind it, the 429 in my '64 made it jump even though it was a heavy car. I read that it could do 0-60 in 8.5. The best milage I ever got out of it was 16 on the open road at 55 MPH, and under 10 in town. Cadillac was about effortless performance as long as you had lots of gas money... I buried the needle when Montana speed limits were "Reasonable and Prudent" on one long straightaway.

Once again, fun but expensive... > 3) Are there any sources for aftermarket performance parts? I'm not aware of any. This was not a popular hot-rod engine just because the parts for it cost too much... > 4) What are its stock HP, torque, etc. specifications? It put out 340 HP. Torque was in the 350-400 range. Compression was 10.5:1 so it's a good idea to run premium fuel. Bore and stroke were 4 and 3.75 inches respectively if memory serves. There was a Carter or Rochester four-barrel carb. Usually the '64s and '65s had the Carter, and I think most later engines had the Rochester. As far as I know they're interchangeable because the intake is the same from the '63 390 to the '67 429. The block and heads were cast iron, and the two cylinder banks were at 90 degrees to each other. The crank-case held four quarts of oil, five with the filter. Timing was set at 4 or 5 degrees BTDC, and the dwell angle was 28 degrees on a fresh set of points. I'm sorry I forgot the firing order. I got rid of both my '64 and '65 in 2002... -'dreas |

Wow, what a comprehensive answer. What's an "integral cooling system
for the heads"? Steve H dreas wrote: > > "Ironradio" > wrote in message > om... > > I have the opportunity to obtain a vehicle with a Cadillac 429 engine > > in it.

"snh9728" > wrote in message ... [Cadillac 429] > Wow, what a comprehensive answer. What's an "integral cooling system > for the heads"? The cylinder heads had their own water jackets to keep them cool. The plumbing looked intricate and great! -'dreas [I had one for eight years and a second one for a year. You tend to learn a lot about what you have if it keeps breaking and you do some of the repairs yourself even if you're only doing an occasional minor tuneup.] |

I see a six thousand dollar bill with wings on it wafting up on a big thermal if such a thing exists. ;-] My recently-acquired 85,000 mile '87 TPI 5speed Trans Am should be good for getting a few speed jollies. It should top out at 140 like my '87 Formula did before I sold it in '93 to pay the rent and get groceries. Trouble is, Montana went back down to 75[?] MPH legal speed limit so I'll need to do it illegally again. *sigh* -'dreas |

It had a bit left, but I had to back down. It took that 302 a long time to get going that fast. It's more of a cruiser, and best suited to speeds under 80, but just trying to get that speedo to register 120 was a challenge. I only do stuff like this when no one else is around and never close to home. There are no roads with straight enough flat parts in BC to try stuff like that... > > Maybe that burst of red-lining it is what broke that piston!

I'll get in too much trouble. ;-) Imagine a horizon far away with nothing between you and it but two lanes of perfectly straight blacktop. Is a red Trans Am speeding in the desert if no policeman clocks it? No cops, no trouble. Of course, I don't do things that are dangerous, and I don't do them often. I just enjoy accelerating and shifting through the gears, taking corners like I'm on rails, and thrilling to the rumble of my exhaust... > 46 is a little old to start getting speeding tickets and license suspensions > for them again. Heh. I'm a professional driver. I don't need any kind of trouble. I need my license to keep me in beer and gas money. 40 is mid-life crisis time, so I got me a car like the one I had when I was twenty-five. The only difference is that I'm old man wannabe now instead of the boy racer that I once thought I was... -'dreas |

Therefore I have some questions: 2 different 429s in 64 one had a crank for the hydramatic trans the other had a crank for th400. 65-67 will not bolt in a 64 since they changed the chassis in 65.(not without some major fabrication) > > 1) Was the design of this engine 'good' or did it have problems? Overheating them will crack a head easy, oil burning in the 64s wasnt uncommon.Average 1000 miles a quart. > 2) Was it considered a 'performance' engine or just 'run of the mill'? > 3) Are there any sources for aftermarket performance parts? none as of yet. Just electronic ignition. > 4) What are its stock HP, torque, etc. specifications? > > Thanks! Thebig429 http://www.1964cadillac.tk |
