Do 8 Stack EFI or Weber Carbs Run Good On The Street?

Throttle response is quicker, car feels faster, starts right up hot or cold, and it doesn't suffer from the run-on (dieseling) I got with the Holley.

Do you find the linkages to be stable? I've heard that many folks have to rebalance them frequently. A friend, not a tinkerer, eventually gave up trying to set them up but I think he was using a cheap vacuum cap.

Can you run a big cam, with little in the way of vacuum ?

I've built a few weber carbed engines of different capacities from 75 - 360 CI.

Each one runs smoother and pulls from lower rpm better than anticipated.

One was so smooth, almost EFI like with a 245 @ .050 camshaft.

It is all about combination.

Yup, no issues.
