ok, things already done to my 287 while it is STILL having this problem are as follows. 16 new pushrods 16 new lifters 8 new spark plugs 8 new plug wires 1 new distributor cap 1 new rotor 1 accel coil 2 heads removed, valve seats resurfaced, valve gides resurfaced 1 new timing chain 1 new crank gear, no cam gear as it was not availible oil changed i am closing in on the $400 mark invested into the engine alone. it is friggin frustrating. i am going to try the exhaust thing. im sure it is not the carb, as i put on a week old remanufactured motocraft 2100 carb, ran GREAT on the 70 torino gt it was for. there was only a marginal increase in rpm's. maybe 100 rpm's. i just got a compression testor. that will be the next thing to check. when i had the heads off however, the cylinders looked great, no ridge or nothing. the top rings i could see did not have any large gap or nothing in them. the mechanical advance seems to be working. in park with my timing light and the timing mark moves. while having it in gear, and trying to get it to move, adjust the distributor, no effect. hear it start knocking when it gets to far advanced thats about it. i am going to disconnect the manifolds, run it strait out of the heads and see what happens. annoy the heck out of the neighbors. dave stohler http://picasaweb.google.com/das24rules ____________________________________________________________________________________ Yahoo! oneSearch: Finally, mobile search that gives answers, not web links. http://mobile.yahoo.com/mobileweb/onesearch?refer=1ONXIC _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list
