Spent some time with those charts you posted up. Decoded my VIN,was quite fun. Also checked the oil galley plugs,yeah they don't exist on this block at all,makes me wonder. its hard to know what all this other person was doing. The plus side is it came with new Mopar Performance Stainless valves. Exhaust valve is 1.60" and the Intake is 2.02" and if i read correctly the 2.02" is what you suggested I used..from a 340? Found the numbers stamped onto my main caps and lined all anchor slots up. Still a very very long way off from actually putting anything together but I have been searching for parts. Mancini is simply wonderful,will be using them for sure. I have found some things on my block though that raises some questions. the VIN that you said is on the side reads 7D2425 5 and i thought that was a bit short and it doesn't seem to have more on it. Also I looked on the block by where the head bolts up for the other number and it doesn't seem to be there eitherÂ….maybe just a lot of grime built up on it as it has been sitting and was passed along in the purchase. Sadly the only machine shop we have here isn't exactly what I would call a trusted machine shop as it is just our Napa parts store who is not well trusted in my parts. Any suggestions on a place that would allow me to ship parts to and from or any other suggestion on what to do? My notebook is filling up quite nicely from your information,I can't thank ya enough.
