It's very hard to accurately predict the hp of a ported motor. Even using the exact same template, two engines will never be ported exactly the same way.

Which bridgeport template did you use?
Did you port it, or did a shop (which one)?
Single or dual-pipe RB exhaust?

In any case, I'm sure it will make fair power, and since you seem to be building it as a drag racing car, then you shouldn't mind sacrificing drivability for 1/4 mi performance. With that in mind your choices of a 2bbl carb on a bridgeport make sense. You'll definitely want to spend some good quality tuning time with it on the dyno though, to get the carb dialed in.

I won't even guess at the power, since I would most likely be off by a long shot, but my guess is "it will make good power for what you want"

Sounds very similar to my mates setup but he's running a different exhaust, he's making around 220 - 230 hp. Depends on as said above: the port size and shape etc. My mates is a full cut bridgy.

My 13B large extend port still smokes him though hahaha!
