Title: 17056564
Post by: bsblguy on June 20, 2018, 06:13:21 AM

1976 Trans Am 400 auto California emissions low mileage. Engine has never been apart and carb has never been off. I want to rebuild carb. Car is stock other than exhaust changed to 2 1/2 dual exhaust, no converter, no egr. I do not know what jets are in it. Is there anything I can do to upgrade performance some by changing jet size? If so, what size jets should I order. When car was built emissions and fuel economy was a concern. Better performance is my concern. I do not want to take engine apart. Slightly better acceleration is fine.

Best to call the shop to order.  We can discuss the engine changes and tuning parts needed to get it dialed in for what you are doing.  We're here 8am-4pm, M-F EST.  Call volume is very heavy so if we don't answer leave a good number and we'll call you back.

Excellent carburetor BTW, same type of carb I use on my own engine:
