Hey guys,
I am travelling for the week and want to give my friend the part # I need for him to bring me in an oil pan gasket for my 400sbc but I am not sure which one I need.

Anyone?

 

It should be the one with the thick front seal.

 

Thanks!

 

That depends on the pan, not the block.

 

Is there an easy way to tell?

 

Turn the pan upside down with the pan rails flat on the ground and measure the height to the lip of the pan in the front. The one for the thick seal will be 1/4" taller. Unfortunately I don't remember what the measurements are off-hand, but it's been posted before, and Google should turn something up.

 

Unfortunately I am 300 miles from my car and want to do it on the weekend when I get back. I'll just get him to bring in both kinds so that I am covered.

 

By the way... if it's the thick one you need, I've got an extra Fel-Pro one-piece gasket in the garage. I measured and then went and ordered the wrong one anyway. :P
