MPG before and after Cam 2000 camaro with pacesetter 1 3/4 LTs, ORY, corsa catback and lid. car is a M6. has stock gears and 853 heads. I drive it to and from FL once in a while and average 30mpg.
Just curious about what you guys average with cam and DIY P&P heads. planning on ls6 intake and probably ms4 cam. Will be keeping stock gears.
Also what lifters if any did you switch off to? Best rockers for a low budget?

when I was just hooker long tubes through the stock 3.42 10 bolt, I was getting low 20's in the city and high 20's and even sometimes 30-31mpg's on the highway. It was actually amazing on gas for having 351rwhp under my left foot....
now I have the ms3 cam, detuned for my nitrous and a 4.11, moser 12 bolt etc. etc. In the city I dont even want to talk about it but on the highway its low-mid 20's depending on how the traffic is and how much shifting I need to do.
The ms3 with the 10 bolt/3.42's was actually really good on gas as well. It all started going down hill after taking away 9* of timing for nitrous, running 2 step colder, non projected spark plugs and of course the 4.11, 12 bolt.

I've put a few hundred miles on my C5 since the H/C swap. Highway mpg doesn't seem to have changed at all. Doesn't make any damn sense. Yesterday going down rt.251, flat as could be for a few miles, the indicator on the dash was reading 36.x-37.x mpg. I haven't really checked but city mpg obviously went down.
