Does anyone know what 4 bl carburator came stock on a 57 Chevy Belair. A friend bought one ,and wanted to know. He wants to get rid of the Holly and put back to stock.
Thanks, Dave |

If my memory hasn't failed (which is highly possible), Chevy used a Carter WCFB four barrel.

Hello Dave, The 1957 Chevrolet 283 with powerglide transmission came with the Rochester 4GC carburetor. Early models were # 7008737 and later built models were # 7009846. John

Perhaps it may be only the dual quad 245 hp (auto trans) and 270 hp engines used the WCFB carbs.

My old Chilton manual shows both used in 57 Chevy applications. Sorry for the error! James Q

My mistake, I always thought all Rochester’s were q-jets. Thank you, I’m a little smarter now.

Carb
Heavy suckers too as the base is cast iron.

Ridiculously heavy carbs. I have a friend that owns a 56 Belair, 57 Belair, and a 57 Cameo and I've rebuilt those carbs plus a spare for each. Doesn't hurt to paint the cast iron bottom or they become a rusty mess in short order.

Thanks again EV1,
Ok , I took the carb apart and rebuilt it for my buddy. The first thing that happened was the power piston fell out as soon as I lifted the air horn up. Second ,the boot on the pump was soft and deformed. other than that ,it was just real dirty inside. Took his car out for a ride after putting it back on and it runs good now. There is a slight stumble just coming off idle ,but as soon as he gives it more gas ,it runs great. I am thinking ,maybe because I did look at the jets that were in the carb and cleaned them up. The primary jets are ,048's and the secondary jets are .068's . Could that be the problem. I think they are too big,and should be maybe around .060's in the secondary's. What do you guys think? Thanks for all the help, Dave |
