Part numbers needed
Hi Guys
this research makes me nearly crazy, maybe you with your experience can enlight me a little bit: My truck: 1968 C20 Camper 327 with automatic choke, automatic transmission TH400, power brake (SPID: L30,N40,M49) For me is very interesting what was the Original block casting number maybe casting number 3791362, 3858174, 3858180, 3892657, 3903352, 3914660, 3914678, 3933180 or 3956618 with GM# 3937295? Original intake manifold casting number probably # 3919803 (GM#3931575) Original carburetor number and manufacturer with wich choke assembly probably Rochester Quadrajet 4MV 7028213 with divorced automatic choke Original exhaust manifold casting numbers LH (driver side) Maybe GM# 3855163 L.H. cast 8155163A or 3855173A, interchangeable 387241 or similiar, RH (passenger side) GM# and casting number 3896956 R.H. (discontinued use GM# and casting number3905364 or GM# and casting number 3932469) Maybe somebody has some pictures, information, documents etc... Highly appreciated! According protect-o-plate the original engine ID was: VO426YV (means 327 from Flint for 3speed automatic transmission with 4BBL Carb, and the original Carburator was C (means Carter) and as the date vehicle originally placed in service (protect-o-plate was 6-29-68) and the car assembly was on 05-02-68 (build sheet) and the engine asssembly was 04-26, assuming 04-26-68. The build sheet stated Carburetor - 8213, assuming means 7028213 Rochester Quadrajet 4MV Carburetor manfactured by Carter (MFD By Carter Carburetor for GMC 7028213). The engine was probably changed during guarantee period with a 327 block 3959512 with ID CE7P27140 as CFB = Counter Fitted Block. The engine has actual an Edelbrock Carburetor #1406 with Carburetor spacer and intake cast # 3960364 ( I cannot find this cast # in interchange books, the only information I found was in internet as follows: The 3960364 manifold was used in 1968 and was cast either 3919803 or 3960364. & This manifold has been found with the casting number 3960364 on it where someone forgot to change the casting number of the mold in the cope. They apparently cast a bunch of them before the QC guys caught on and changed it (too many to scrap). The interchange manual stated for 1968 327 truck intake manifold casting number 3872783 four barrel cast iron, some other sides say until 1967 only and the 3872783 manifold has sqare bore design (Holley, Carter?), assuming the Quadrajet need spread bore design? The Chevrolet truck part catalog october 1969 stated for 66-67 GM# 3888885 (casting number 3882858) und for 68 GM# 3931575 (casting number 3919803).

Re: Part numbers needed
What's the OP trying to find out or prove? These aren't 70 LS7 Chevelles--they're million a year built pickups. I imagine many of the engines installed were the same as those in Impalas, etc. of the same vintage.

Re: Part numbers needed
Thank you so much for your replies, very interesting. The 803 is exactly what I have expected, match the assumptions with the "production failure" during molding.
Dear Franken you are right, but for me my beloved truck was only one time produced, I know some milestones about his live and I like to research about the history of this car and about the history of the related humans, cities and Gods Country. Furthermore I like to improve my technical knowledge by dealing with the issues and books. Last but not least it is a pleasure to communicate with you as experts here in the forum. More information highly appreciated.
