340 intake/carburetor advice

appreciate
Appreciate the insight, I had the AVS2 at the top of my list, till someone talked me up to the Thunder. Looking at stock, will check into M1, it's a 69 motor. I will probably stick with the A904 transmission, and one day, good Lord willing, a 8- 3/4 3.91 geared axle, upgraded suspension, brakes, etc...

I had the 904 with 7.25 and it was great.

Just finishing up the 8.75 with 3.23 and sure grip as well as new brakes and suspension. I'm assuming the carb will still be great next week!
