engine questions

so i replaced my valve cover gaskets and the ones that were supposed to fit.. were too short... me and a buddy spent about 30 min looking for any engine id numbers... the only thing we found was a number on the block.. i doubt 201 can tell anyone anything but thats all we found... does anyone know exactly where to look??? also if i go get 305 vavle cover gaskets and they are too small again is it possible i have a diferent engine?

Aren't all small block Chevy valve cover gaskets the same?

Only exception might be '87 and up with fuel injection.

I think its on the flange area at the back of the engine where the trans bolts on to the engine. I think its on the driver side. All older small bock chevys have the same gasket till around 85 or 86 when they went to center bolt valve covers. Cork gaskets will shrink when they get old that may be the problem.

ok... i'll lok there when I get a chance.... no telling exactly when the gaskets were bought... so i'll pick up another set and we'll see if they fit... when we opened the vavle cover we found large bolt inside under the lifters... no telling if that was helping or hurting... that's for the info...

You could get them wet and they'll grow some.

Yes, the block casting number is on the driverside. There is a flange that the bellhousing attaches to and its on top of that. I will try to get up a pick tommorow of the block i have in my garage. That # will tell you alot about your engine.

Actually, the number on the back of the engine is just a casting number and is pretty general. It can give you an idea, but wont give an exact year or detailed info.

To get a little more accurate you need the serial number. It is stamped on a flat spot on the pass. side right in front of the head. You may have to pull the alternator to get to it. It can tell you what year and vehicle(s) it was used in.

The valve cover gaskets are the same on all small blocks until 87 when they switched to center bolt covers on the tbi engines.

The ID number on the drivers side rear flange will give you year and block description. Any numbers on the heads ID the heads, each part is seperate..

On the driver side, top side, right behind the head on the bolt flange to the transmission. You should be able to see it with a flash light. If you can't see it then it is probably covered by dirt and oil.

There is a number stamped on the block in front on the passenger head. That is the block serial number. The head casting numbers are under the valve cover.

Once you get the casting numbers, go here.

http://www.mortec.com/

They also tell you where to look for different places with different ID numbers. Good info.

Its possible someone gave you gaskets for the old 305 v6. They would be shorter.

I would think the 305 v6 would be more than 1/4 in short but maybe, It may be that they just shrunk, What does the package say?

valve cover gaskets are cheap, not really worth hassling with old ones.
