Repro Pontiac round port/Oldsmobile W30 cyl heads

[SmallHurst]

Unfortunately for Olds, most all of the value of the car (or clone) will go with having the correct heads. For the '69 H/O (I will speak on that car because of my experience) documentation is very iffy. So when documents become iffy, the parts of the car start to lay out the truth of the vehicle. D heads were only for '68 and '69 w-30 cars and '68/9 H/O's. F heads only for '70 w-30 cars and H heads for '71 w-30 only. For the '69 Hurst, the heads, mirrors, intake, wheels and transmission codes were special to the car. Outside of those parts, everything else was standard issue Cutlass and 442. Recently, a partial list of cars converted at Demmer Engineering was found. Unfortuately, it is not a complete list. 2x for me as my car was not on that list. I know that my car is ligit, but paperwork is not there to support it. I have owned my car for 12 years now and I talked with the second owner of the car.

Now, we have reproduction mirrors, hood scoops, rear wings, dual gates, consoles, rims can be made, rough intake manifolds, and now reproduction heads. Soon, someone will come out with transmission tags. At that point and time, I will have what my car really is, a glorified 442 with special paint. I know that it really won't affect me because the car will not leave my possession, but some guys who bought the cars for money will really be crying the blues. It will turn into a 2 class system. 1)that you are already in the loop and might be offered the cars that are true and rare and will have opportunity to own a real car, or 2) you will be on the outside looking in and getting duped with clones.

I purchased a real '70 W-30 from the original. After about 10 minutes of looking for a build sheet I found two. The original motor was long gone since the seventies.So,if I buy a pair of new repop casting for $2,500 rather then a original pair for about $10k(that might I have a defect)that would make my car any less real?

That's a great point. What about the guys with the paper work/ documentation and their motor is missing or the heads are cracked. Now they can go out and get a repop set of heads and not have to refinance their mortgage to do it.

it is still a documented 70 w-30,which is still rare,no matter what heads are on any motor.
what people seem to forget is 455's were toast after being beat on back then,and most original motors were chucked after puking their bearings,or crank.
so not having the original motor is somewhat of a big deal,having the docs to prove it's heritage makes a difference,too.

You just need to give "Parts Joe" a chance. I am sure he will start reproducing the Oldsmobile 396021F 455 blocks among others with blank engine ID pads very soon. Maybe it will come with a complete re-stamping kit so we can all get our clone W-30s or LS-6 Chevelles perfect. Hey maybe he will also throw in a perfect reproduction broadcast sheet and OW trans tag at no extra charge. Great post Rusty-it said it all-Thanks John
