i have a 1970 cutlass withand olds 455 in it and has been running good for a while, recently whenever i turn off the engine and knocking and pinging noise will occur then shoots out gas out the carb... (will sometimes have to click key forward, the engine starts again then shuts down when i turn off) and makes same noise then stops.
We understand that there is a timing problem and it need to get fixed. we went out and bought a timing light. noticed that my car does not have a timing tab on it. we pulled one from the junkyard(68 cutlass)(engine was torn apart and didnt know wht size motor?). is the timing tab for the 350 equivalent for the 455 engine? also noticed that the distributor doesn't have a hold down bolt...all got that out the junkyard. we dont want to rotate distributor until we have a fixed point to see where the current timing it atand make it any worse... need to see if timing tab will fit and if its the right one..

OVERHEATING problem... bought the car from port allen baton rouge and drove it to destrehan( by New Orleans) and it had no problem overheating, stayed around 190-200F. when in neighborhoods, stop and go... or stand still itll get up to 210F quick. car DOES NOT have a theremastat, we have replaced the seal on the theremostat housing and noticed that there was no thermostat in there. ( recommend getting a thermostat 160 degrees?) my dads 70 cutlass (455) has one and maintains a temp of 170-180F, and alos we are about to change/flush the radiator fluid and see if that will make somewhat of a difference. but does not having a theremostat in the car cause it to overheat. i have electric fans that kick on around 130F

i also wanted to knwo wht is the correct spot you install the temp gauge monitor, mine is located in the back . wanting to know if it needs to be installed in the front to get a more accurat reading?

please read, need to get these problems fixed! thanks

put the distributor hold down on and time it, your car can over heat if the timing is off and your car will run bad with out the distributor held in place, that sounds like teh problem
