The stock radiator always cooled fine for me. I don't think the L-head had a bigger radiator than the OHV, I'm pretty sure they are the same, but I did have a radiator that came from an L-head car (had been recored for an earlier car I had, swapped the old original out), and it was a pretty new one (recored again after an accident holed it).

My 63 Classic 770 with a 287 has Engine Thrust Bracket Assemblies on both side of the automatic transmission. It's on page 2 of the technical service manual. I cannot find anything to replace the bushings although I did find a listing for Transmission Crossmember Side Mount which is a part of the assembly. I am looking for a substitute for the bushing in the arm/rod part.

The bushing in the thrust arms is very thin and hard. I haven't had any issues with just leaving them alone. The rubber side mounts are a different story!

well i added a thrust rod on my 195.6 OHV in '61 american, i made a bracket that bolts to the passenger side studs that accepts a heim, and two ears to accept a heim joint on the rear enging crossmember. with no rubber isolators i assumed i'd be getting a lot of noise and vibration -- but there's none at all! thinking about it, i realized that nothing in an internal combustion engine generates any motion fore and aft. nothing at all! there's certainly a longitudinal "S" shaped oscillation but that's tiny, and again, none of it's longitudinal. i did it to save my crappy motor mounts. i drive this thing hard, and tore all my mounts out. next i'm going to tie it down for engine torque (all 200 ft lbs). again for weak mounts, not due to terrifying power (i wish :-) |

Hello I was reading up on your post on the engine/ transmission thrust rods with on ur 287, did you happen to come up with a solution for the rubber bushings? Mine are also worn out and looking for a solution! Thanks , Matt

I found some shock bushings. I pressed in one to see how it looks. Seems like it'll be good after I install them. I found two different ones and have only tried one so far. I haven't had the time to actually put them in the car to see how they work. It is in another location and time/weather hasn't been good for me. Let me try this link. http://s81.photobucket.com/user/ervsuzrv/slideshow/63%20Rambler - http://s81.photobucket.com/user/ervsuzrv/slideshow/63%20Rambler

hey, a minor note on the thrust rod i added last august, after driving on it for 7 months: it transmits ZERO (0) noise or vibration to the chassis, even though mine is simply steel heim joints. at first i was puzzled by that, until i realized that there is no mechanism in the engine (or really, any conventional engine) that moves fore-aft! nothing. up, down, side to side and roundy-round, but no fore and aft. all vibration and oscillation in otto cycle engines is in that one plane! (some complex motion up where the long six cyl crankshaft generates longitudinal waves, but thats weird an small -- and still not longitudinal). |
