Disassembling the 383
the future power plant for my duster....
Just a little history on this particular engine. It was originally out of a 68 Roadrunner owned by my friend's...Dad's...mechanic buddy (Fred). It has rebuilt some time in the early 90s, bored .030 over, 12:1 pistons and a beefed up valve train. So said the roadrunner was running somewhere in the 11s after the rebuild.. dunno how true that is. Well, the car was wrecked shortly after and the engine was pulled and put in storage in my friend's...dad's shop. It eventually got acquired by my friend (Fred is an alcoholic and need drinking money, lol). And I bought it a few weeks ago. Anyway, I finished tearing it down yesterday, here are some pics of the dismantling..
It was fun getting this heavy sum-***** out of my truck all by myself...
First off was removing the harmonic balancer and timing chaine cover. Im sure there are a few brown recluses living in those water jackets.
Timing chain had about a 1/4" of flex. Every thing looked fresh, but i will be replacing the chain and sprockets anyway.
I'll be reusing this..
Missing a few push rods, Fred probably needed something to stir his jack and coke with. lol
So said this is a high lift cam.. I have no idea how to identify it, other than measuring the cam lobs, which i will probably do today.
Here is a shot of the #8 piston, Manley P5593 pistons .030 over. They have fairly large domes, so the 12:1 claim is probably true. I tried googling the part number but couldn't find anything.
2,4,6,8
906 heads, probably the original ones that came with the engine. I didn't get a shot of the valves, but they appear to be in good shape. I'll probably reused the heads as is, might get edelbrock aluminum ones later down the road.
Time to tackle the bottom end.
Looks like the #3 rod might be bent..
Found this guy sitting on top of the windage tray...
Looks like Fred used a bolt that was a little too long on this one.
Looks like the #3 piston skirts are toast.. I probably have a bent rod. what do you guys think? There is some vertical scoring evident on the cylinder wall as well, I'm not sure if it can be honed out or not, but sense i probably have to get new pistons anyway, i could bore it another .030 over. Guess I'll find out when i get it to the shop. All the other pistons and cylinders seem to be in great shape aside from some light surface rust in a few spots.
ready for the machine shop. Hopefully it checks out to be just fine.
