I don't know if a muscle mass range per height or build has been or can be correlated with longevity. Some of the parameters that have been studied scientifically are associated with lowering risk factors for heart disease and cancer.
You can be very muscular and have a normal body fat percentage, but if your cardiovascular shape is poor, ie high resting heart rate and hypertension, then you will have decreased longevity.
The overall number one cause of death in the US is heart disease, but the over 85 group skews the data. If you look at the entire population under the age of 85, the number one cause of death is cancer.
In my opinion, the most important actions you can take to live long and strong are:
1. Cardiovascular training to a resting HR<60 and BP<110/70 and a healthy (no fast/fried food) diet. Most physicians recommend a minimum of 30 minutes, 3 times a week with a HR at least in the 60-70% of your max.
2. Annual physician checkup and lab tests
3. Low triglycrides and high HDL/LDL ratio
4. A daily multivitamin, if not to supplement your diet, then to at least provide antioxidants that can reduce the risk of cancer.
5. Always wear sun screen when exposed. Sun burn related cancers catch up to you in old age, especially if you are fair-skinned.
6. Medication compliance if prescribed by your physician. It is unlikely to have a condition that requires medication if you follow 1-5 and don't develop disease. Unfortunately, genetics and environmental exposure do lead to disease, thus the crucial nature of #2. If you start treatment early, most diseases can be either kept from progressing or even cured.
7. Injury pervention is a whole topic by itself, so I will just say be smart when you exercise. Get the education you need before doing something new and make sure you are doing it right. Stretch before and after religiously. Rest days are as crucial as your training days so don't sacrifice them.
I won't bother listing obesity, smoking, drinking alcohol, or elicit drugs since I assume you already know that. They have been shown you to accelerate physiologic age. I've seen patients in their 40's with bodies that function like a 90-100 year old's (multi-organ dysfunction if not failure).
I bike or run on my off days for my cardiovascular workout. However, when I lift weights, I do circuit style training to increase my heart rate and rest no more than 30 seconds between sets. This approach adds to your cardiovascular fitness.
If you take supplements, roids, or GH, then #2 will be very important because it is possible to over do it and damage your kidneys, liver, and heart. Steroids have been associated with hypertension and development of heart disease. Supraphysiologic levels of GH leading to high IGF1 levels will increase your risk for cancer.
