Of these four sizes, the only two that got a reasonably universal thumbs up during my investigation of Type I engines were the 1776 and 1915. I highlighted these portions of the EvilAngel's post below because I think it bears repeating -- especially since you brought up reliability.
BTW, reliability is easy to understand but hard to define. Everyone's definition and threshold will be different.

I am not expert enough to comment on any other details and won't pretend to be.
I will say horsepower and torque are fleeting numbers and can vary within the same hardware selection. Another aspect on horsepower and torque that warrants emphasizing is these numbers will vary with the same exact engine and combo depending on where it is measured.
For example, the original engine in my '71 was as stock as stock can be. The owner's manual lists it as being 60 bhp at 4400 rpm and 81.7 ft-lbs. at 3000 rpm. It was measured on the dyno during November 2005 at 44.5 hp at 4200 rpm and 69.2 ft-lbs. at 2700 rpm.
If one of the experts chime in with a guesstimate or a range with your hypothetical hp, they are more likely to spout a dyno number as the experts I have listened to have access to, have had access to, or own a dyno.
