Rochester Carburetor

[James C.]

I have a 1971 LS5 4 SPEED that has a Rochester Carb #7043202 A 3.. F 5 code. I know it is the incorrect one for my car.I was wondering what it belonged to. Does the manual still require the carb date to be within 6 months of the date the engine was built. (still no judging guide).There is one on EBAY that is 210 days before my cars manufacture date...I don't want to waste my $$... Thanks!

Jim,

According to my NCRS Pocket Spec Guide, the 1971 365 hp 4 spd engine used a Rochester Quadrajet part no. 7041205. If by chance yours is the 425 hp 4 spd then a Holley 4150 R4803A part no. 3986195 is used. I cannot address the carb date issue, you will have to check with someone else.

To meet NCRS and NCCB judging standards the carb date code must be within 6 months prior to the car's build date. The carbs were installed at St Louis, so there's no real relationship between the engine build date and the carb.

I think a 7043202 was corect for a 73 Corvette 190 HP base engine auto THM. I have owned a half dozen of them and they all had 7043202's.
