engine,cylinder head,etc...
I found the engine to be original, a 350/300, it may have been rebuilt, for it runs great, was very clean,has a different intake, carb, and right ex. manifold, the freeze plugs look very new(all of them), quite a few signs of a rebuilt....the casting numbers on the BACK, end with 010...someone told me that was above standard motor, is that so??
and i don't know for sure what the heads are, i think 202s, i can see 2 camel humps on the front edge, but no numbers...any way to tell without pulling the valve covers?
can I wire wheel aluminum valve covers safely? i'd like to polish them.
are the bushings in the control arms universal to other GM cars,or must they be corvette only? they don't stock corvette parts here,per say, but they do stock standard car...thanks Tim

I'll start with the middle question. I don't believe that the 300 HP engine had 2.02 intakes. I'm just working through this with a set of heads that I got on a motor. As I understand it the same castings (and numbers) were used for both the 350 HP heads (2.02) and the 300 HP heads (1.94). I also don't believe that there is anything external to help you tell the difference.

There is no way to tell if the valves are 2.02"/1.6" or if they are 1.94"/1.5" from the outside. 1970 model year double hump heads with the bigger valves will have screw in studs & guideplates but that would still be inconclusive as someone could have added them later. Put your betting money on having small valve double hump heads as they were much more common back in the day. These days factory big valve heads are very very scarce.
