Best Cam LSA for MPG
Assume something like a 220/224 cam in a 6.0L. 10 to 1 c/r with all the bolt ons. What would be the differences in MPG between that cam with a 112 LSA and the same cam with a 115 LSA? Highway cruising at 2000 rpm. Guess you'll have to assume an optimum tune for each cam. I understand the effects of different LSA's on idle, power band, etc. Your thoughts appreciated.

To actually answer your question, its overlap that you should reduce in order to maximize fuel economy.
In this case, since both cams have the same intake and exhaust durations, you can say that a "larger" LSA will have less overlap and will theoretically get better mileage.

My truck went from 20mpg highway to 18-19 as it sits rt now.. I don't feel like I lost much.. 5.3 stock with 3.42 to 5.3 10.5:1 compression LT headers 4.10s 30" tire 222/226 111+2 lsa cam and 3600 stall... I don't c u loosing MPG with a 111-115 lsa cam.. only reason I might have lost MPG is because I went from 3.42 32" tire spinning 1700@70 to 4.10 with a 30" tire spinning 2300@70 but not because of my cam
