I have purchased an assembled/rebuilt 302. After firing the engine and driving <50 miles it developed a strong vibration and a knock.I want to learn how to tear an engine down and re-assemble it. First questions I have are what books should I purchase and what "special" tools will I need? Hopefully it will be bearing related, and I will not have to rip into the shortblock any at all. Thanks, Dan

Dan,The bearings are in the shortblock.  Lots of special tools involved. Are you sure it isn't something simple like ignition ... I can hope for you,,  Tell us everything. SteveW

Busted flywheel can cause a vibration and knock. So can a rocker arm problem.------------------

ah man. I'm in over my head. I need to read up on this before I commit to even trying to do this myself. Any recommendations on books?

Try explaining the symptoms first. Is the vibration and knock under power or coasting, or both? Did the tranny come out during the engine change?

The vibration and knock only occur under power, i.e. as you accelerate into higher RPMs. The c4 was removed and reconditioned, new bellhousing (v8) and torque converter were added. Here is a link to a prior posting; all recent info is toward the end... NEW MOTOR HELP
Please note that I lost ALL oil pressure, albeit a short time the motor ran with zero pressure, but it did. Thanks for any help, Dan

I would try to rebuild it myself. If nothing else it would be good just to learn how. The 302 is probably the easiest, and cheapest motor to rebuild. The first motor I ever rebuilt was an "81" 302, and it ran a little over $700. But I had the block and the heads hot tanked, and the block bored 30 over. Starting out I wouldn't try to mess with the heads though (unless you have a machine shop to reseat the valves yourself. The most important thing about rebuilding the bottom end (personally) is to be sure of your bearing clearance (main bearings and rod bearings), check for out of round cylinders, crankshaft, and rod ends. and remember to hone the cylinders before reinstalling.
Also can't stress enough.....pre-oiling is the secret to engine life.
(to check out of round you need a dail indicator, not hard you use once you figure it out.) [This message has been edited by 83T-bird (edited 01-14-2005).]

The engine lost oil pressure while I was under the hood. The car was ideling for maybe 10-15 minutes while I was making adjustments (timing/carb). I then got in, didn't look at a gauge (dumbass on my part) and started to drive down the driveway and go around the block, that is when I noticed and shut it down immediatly. I did not make this clear but I'm 100% it's suffering from some major oil starvation issues. Do you guys know what I might have toasted or what I can expect to be ok?

No oil pressure? How about the pickup for the oil pump? Did you pull down the pan to check it out? ------------------
My interests? Finishing first w/o breaking out
