I'll guess 325.3 HP.

Do you know the intake duration at .050" lift of your cam?

My guess is stock heads. 300-325 sounds about right.

OP, this question gets asked time and time again. The real answer is "Who cares?" How fast is your vehicle? What does it do in the quarter? Is there a HP level you must have to do a certain chore around the house?

If you really want to know how much power it makes, dyno it! Race it! Other than that, you're just guessing at a number to throw around at the next bench racing session at the local drive-in.

I think I can come pretty close, I have dynoed 3 cars in last two months and one time there was a guy there just before me that had a 79 Camaro and he was saying he had about the same set up as you are saying but if I recall his cam was a hair bigger and it did have a little lope to it. but he called it a 383, not a 355- I have no clue the difference.
He ended up at about 245-255 HP, so would assume about a 300 net going through a 5 speed.
He just knew it was going to be 450-500 hp and was pretty pissed, his mistake was listening to his friends guessing HP.
