now for the expensive stuff
head gasket - compesssion check is a good test but usually would get the tell tail white smoke outa the exhaust,

cracked head or block well you would have antifreeze

 

in the oil, i think that all i got for now did i miss anything? o the heater core, un hook your lines to it and take the garden hose to that too (thanks drewski)

 

Man i hate only having 200 letters to post with

 

so do all of us reading your posts Justin, everytime I hit new post there is another one made by you! you may ask why am I reading about a 72 350 motor? because I like reading posts, OK, good info Justin, hope it is what he needs...

 

=P here's another on for ya Chris! i hope so too that was alot to do on my phone... man i wish i could afford to get then net but happy to help 200 char at a time!!!

 

Check to see if your timing chain and gear are installed correctly. When my 396 BB was built for my 70 monte, the guy had mine installed 4 degrees advanced and I was having an overheating problem and my radiator was recored and was a heavy duty unit as well as a new water pump, thermostat, hoses, etc. Another guy found the problem and installed everything straight up and my overheating problem went away.

thanks guys i appreciate the help. i replaced the tstat already im gonna try flushing the radiator next. do you guys think if the radiator is not plugged and not leaking that it may be something from the install. the engine i bought is from www.unitedengine.com its the 350 v8 4bolt all we had to put on was the accessories that why im wondering if he didnt put the intake manifold on right if it would leak air into the system and if that would cause the overheating by the way we bypassed the heater core until i buy a new one. thanks guys the help its really appreciated.

 

bypassing the heatercores should not cause overheating i have a buddy who put plugs in and never had an issue

 

Holy jeez, thats irritating to read all the tiny posts...

 

It's all i got! better than not helping a fellow MC owner becuase of it
