I listened to your clip. The car is not bogging at the hit it's bogging a few feet out which would indicate that it's running out of pump shot.You can correct this with a smaller squirter or a pump cam with a longer duration. Also check the float level's you may want to raise the rear float a little higher than normal and or add float extensions. If you haven't done so already put some lighter springs in the distributor to get your advance in quicker. And 200 is way to hot you should try to go into the water no hotter than 160. Good luck I hope this helps.
