Hey guys –*I've got a 460 that was rebuilt a few years ago after a spun main. Cost me a pretty penny, but it uses oil like crazy (the builder thinks it was a bad batch of rings from the manufacturer, since he had a similar problem on another motor he built at the same time using the same rings). I need to yank the motor and take it back to him to fix, but I haven't had the luxury of being truckless yet.
Anyhoo, this thing runs worse now than it did before I had it rebuilt. I'm using the same Holley 850 that was on it when I got the truck (shaved air horn, no choke) and I think that may be one of the main problems, but I thought I'd ask for some opinions here.
The truck has a nasty habit of dieseling like crazy when I shut it off and will do that wheezing sound after rattling alot, then I usually get a big puff of white smoke before it finally shuts down.
Could I solve much of the problem by junking this carb and getting another? I did a rebuild kit on the carb and had it tuned, but now I've spent probably as much money on that as I would've just buying a good, new one. Could the fact that the cylinder walls are probably varnished pretty good by now also have anything to do with it?
Any thoughts? I appreciate any ideas you guys might have...
