I will go back tomorrow and re-check, but I was pretty confident that's what is there. I wrote it down as I looked. Which numbers would be more useful for me to look at? The one I posted is the stamp on the pad by the distributor but the only obvious casting numbers I noticed were on the manifold.. Which I wouldn't think would tell me much as it could be changed. I'll try to get a good pic too. Thanks for taking the time to respond! Greg
