Knock on a 300 , I don't know if you read my thread on my 95 300 , 300 rebuild and modifications I think is the title , rebuilt the top end and got 35 hours on it and developed a knock ( I would relate this knock to the sound you hear when you over shoot an engine with starting fluid , more like a cluck , have you ever heard that knock ) , I thought for sure it was the connecting rod , upon disassembling it I found the new OEM timing chain had stretched out way past the adjusters max , I now think the knock I heard was caused by the engine being out of time , and when I say out of time I mean the cam shaft and the crank out of sync from the excessive slack , I can't tell you for sure the knock is gone even though I think it will be , new chain and cam sprocket are here but I am too tired again today to put it back together , I didn't change the cam sprocket when I re-done the top end and timing chain , I think that was the mistake as the old sprocket had wear and changed the pitch and it ate the new chain up ----------It really isn't that hard , you should have a manual , parts cost $500 to do the upper and timing chain , add another $40 for the cam sprocket , you would need a torque wrench and a valve spring tool for the valve stem seals and to lap the valves , a lap stcik and some valve grind paste and some Honda Bond , I used G+H for the boring and parts , for $220 you send them your jug and they send it back bored with a Shindy piston and rings sized to the jug , they give you a wrist pin and clip , head and jug gaskets , exhaust seal and valve stem seals , the timing chain is $99 OEM and the cam sprocket $40 , the rest of the money is on side cover gasket , kick starter seal , reverse lever seal , decompression seal , air filter , oil filter , and what ever else I missed ------ I will give you as much help as I can
