    Whoa, zero to sixty in nothing flat, zero to eighty, no way. That's some serious gearing.

    I'll bet the results will be much different if you drive 200 miles.

    That's a short drive, but it shows what can be achieved when attention is paid to the tuneup and carb setting details. Your engine is most likely one of the "good" cores from factory, don't part with it.

    I track my mileage 1-3 times a summer, but on longer rides, 150-200 mile round trips, ave speed of 75-78 MPH or around 125 KPH. With 520-540 HP, 5 speed and 3.73's I'm at 19-20 MPG, looking at 21/22 MPG this summer with my new combo. City stop and go is not nearly as good or even close, manual, light flywheel and constant on/off throttle kills the MPG LOL

    I drive/track my car all the time in the summer, no truck, no trailer. I also use it as my test bed for other R&D reasons. Using fuel and not getting the energy out of it is a waste of money, and is hard on the bores/oil. And paying almost 6$ a US Gallon adds up. Many races are won on fuel mileage, and big money lost on being "under weight" after a WIN...ya, lots of time on the dyno for sure...

    Oh yeah, much different, from what I remember engine was running around 4000 rpm 60-65 mph. Did the job for street racing though. I had super stock formula 1’s bias ply tires, turn them into cheez whiz all three gears..

    Nice over all combo! I’m wanting to put some more miles on the car now, along with longer road trips. I see your gas station is in litres what part of Canada? I’m from Victoria BC, last summer I was paying $1.78 per litre for 94 octane.

    Wow your Province is really sticking gas prices up your ars. In Ontario we’re in the low 70’s/L for reg. You need to move.

    BC has alway had expensive fuel...heavy taxes. With the price of oil now, we have a bit of relief at the pump reg. 102.9 and the chevron 94 is down to 126.9. Far cry from gas prices east and south of us. I guess if want play you gotta pay.

    Sorry, should have added that this pic was taken last summer during the fuel spike. And I live in Ontario, paid .65 cents per litre the other day !! Wonder if it will go up this summer ?

    when I bought my camaro in 78 fuel mileage was 17mph, next year built a new engine 355, turbo heads, 151 (327/350) cam 11:1cr, torker intake manifold holley 750dp and got 18mpg. Next year changed cam to crane .488/508 lift 234/236 duration at .050, intake to victor jr and gears to 4.56s. Gas millage went down to 9 mph. Had to run 3800rpm at 65mph due to drone at 3500 at 60. Took a trip with it to Newfoundland from Saint John NB, 400 miles then a 18 hour ferry ride to Argentia, Newfoundland. On the way home there is a 3.5% grade for 5 miles great place to pass take it up to 5000rpm just sit in the passing lane. Here is some pictures of Kelly's Mountain
