Many here will disagree with me on that one. My opinion on the 750 carb on a 355 is that it is too big for a street car except for a real gnarly and high-reving small block.

The 750 was maybe a little bit faster once the motor was under full hammer, but not enough to justify switching out the 600 and losing the driveability of the car.

I am fairly good at tuning the Edelbrocks and even with a series of jet, rod and spring changes, I could not get the 750 to drive as crisp as the 600. I was able to get the 750 to run well on the top-end but couldn't get it to run very well at part throttle, especially from cruise to WOT. I tried a 750 Edelbrock instead of my 600 to see if I was leaving anything on the table. I had a very well running 355 with a similar set-up you have and a 4-speed with 4:10 gearing. I was in exactly the same boat about 2 years ago as you are now (even with the new baby). Do I need more timing, change rods and springs, jets? I have very limited time to work on the car lately with a new born in the house, so any help would be great. This is a new top end kit and tuning is not my specialty, so where do I start. Then on my way back home, when I let off the throttle to pull into my driveway, it took the rpms a second to drop.
Slowly increasing the throttle didn't make it pop. It only popped through the carb if I hit the pedal quick. Letting off and the car again ran fine under little throttle. When I gave it a bit more throttle, it popped through the carb. Took it for its first drive and light throttle response was great. My car idles fine and revs fine in neutral. I rebuilt the 750 is to stock specs and it also has an electric choke. I decided to try my 1407 750 carb instead of the 1406 I also have. 050, performer rpm manifold, msd ready to run distributor set at 12 degrees btdc with 37 total.
