Rene, go with alum lowering blocks, some have a degree adjustment already built in so your pinion angle does not get impacted. I do not see any issues with lowering blocks, and a good way to dial things up. I am seeing guys here buying different sets of leaf springs all the time because they either sat too high or too low, so the blocks will definitely be a inexpensive and easy option to dial in stance until you swap your springs. Also note there are steel blocks that can be tack welded on the mounts if you chose to stick with blocks.

registered and insured the bird on friday. took it for a ride yesterday and the smoking problem seems to have gotten really worse in just a few miles. It was pinging, then when I came to a stop light it would smoke for a bit, then taper down, but it really smelt bad. I'm gonna have to pull the heads off and check them out.

try some engine Restore, cant hurt,

whats the pinging from, is the timing screwed up, carb running to rich, is it oil smoke or unburnt fuel???

I dont think pulling the heads will help till you figure out what it is,

I'm not sure steve, it wasn't pinging at first, then started, when it started pinging thats when I noticed it would smoke alot from the back for a few seconds when I came to a stop, and it smelt like burnt oil extremely bad. I have no idea what it is.

I'm thinking its the valve seals, because I never had these problems before it went into the garage.

before you get crazy and pull the heads, do a compression test, and check the plugs again,

and you can change the seals without pulling the heads, get the cylinder on TDC, fill the cylinder full of air, use a long arm tool, or small spring compressor then pull the spring and replace the seal reassemble and repeat!!!

Well after some investigating last night, I've got some very small amounts of antifreeze leaking from the rear of the head gasket on the drivers side onto the back of the motor. I wipe it off and a small amount starts streaming down again. I haven't checked the pass side, but either way both heads will have to come off. might as well get a small valve job done and freshen the heads up while they are off.

Steve68 · #98 09-19-2012, 01:36 PM

and that right there Rene, is a reason to pull the heads!!!!

Look what poured out of the collector after i unbolted it

Looked like it was mostly at cylinder 5

I might just get new head gaskets and valve seals but leave the rest of the head alone. I've got a 350 4 bolt block that's been laying around that I should start building up. Thanks for your replies Steve, you seem to be the only one giving advice lol

Rene ouch, that is definitely not a good sign. new gaskets, etc, and then do a compression check, also any oil on the coolant (on radiator)?
