Approximate Horsepower ???

[BANG]

I am about to have the following work done on the 1980 L48

The speed shop owner is gone for the weekend - so I can't ask him.

Adding Cam <270> Alluminum heads / headers <Dynamax> and true dual exhaust. Changing the rear end from 309 to 355.
I know this info is incomplete - but is there a ballpark estimate from you guys as to the end result HORSEPOWER?

If I had more info on the cam and heads/lifters - I know you could nail it down.

Looking for ballpark numbers.

Thanks
