tks, but damm it I sold a solid 327 this last summer thinking it would sit there like forever. When this one craters think i'm going the 350 route since its going in a '69 elco and the 350 was pretty much the standard engine for them. Thought about an LS conversion but too much dinero and the 350 turbo trans has been pro rebuilt and is solid.
My sister purchased a immaculate 70’s Olds, but it had a knock. I pinpointed the noise to timing chain area and suggested to the brother in-law to open it up and take a look. Swing by and borrow my harmonic puller and get to work, I told him. He came up with a different idea. Tried walking out of the mall with a puller shoved in his pants. He fought with security and that added to his sentence. Eight months in the county jail. Dumb ass. Sister needs to move in with me for a couple of months. So I tackled the job on the Olds, removing all the crap to be able to place the puller on said harmonic / vibration thingy. Reached down and it fell off in my hands. NO PULLER REQUIRED. Well there’s the KNOCK. Eight months in the County Jail for being stupid.
I've had a lot of 307 engines --all had a piston slap or a wrist pin knock. tore them all apart but had no bearing wear. OF course there's always that one. if someone has put a 350 cam from an older 350 in it they had a run of bad cams and the lobes would wear down but you should know that by now. Take the oil filter off and cut it apart and look deep in the paper pleats of the filter -- look for metal that will tell you a lot if you know what kind of metal it is aluminum or steel. Aluminum is bearings and some steel is just due to age of mileage on engine.A good mechanic could tell you alot by looking at it. Just my opinion and as you can read everybody's got one.
b been just playing around with the thing, doing some of the stuff recommended. Did find something interesting, plug on #2 seemed fouled with sooty carbon and didn't appear to be firing. Rest of 'em were clean as a hound's tooth. It has an hei and i had 'em gapped around 35 or so, opened them all up to 45 and replaced the plug with a good used one. Next I'm going to pull the cover and adjust the valves on #2 while its running. ---and a passing note, the exhaust manifold on that side had a shield for heat protection on the bottom, it was simi loose, made a slight rattle, so i took it off---it might have been the culprit, haven't checked yet. ---and you're dead right, opinions are like certain body holes.
Long time ago I invested big bucks in a top line Harbor Freight in line spark tester-damm near $5.!! Used it on the wire and it showed good. I'll change it anyway, just don't tell HF that I even considered doubting that fine piece of Chinese technology!
