Hi hotrod_nova,

I ran that cam in two 406's that I had with 1.6 rockers. I really liked it. In my 69 Vette it ran 11.18 @ 122MPH. In a tubbed Nova with fiberglass fenders, hood, doors and trunk lid it went a best of 10.72 @ 121MPH.

A buddy of mine bought the Nova and put a 355 in it with a 292 Cam with 1.52 rockers. It had double hump heads that had a lot of work done to them although I never saw flow numbers. It ran 11.39 @ 117 MPH.

The 406 I have now runs a Extreme Energy 284H with 1.6 rockers. I don't have any drag figures on it yet but on the DYNO 2000 it looks stronger than the 292H. I went for the 284H because I think it will give me more vacuum for my power brakes.

Is the weight of 3266 with you in it?

well, thats what the scale says at the science center here in columbus. whether it is accurate or not i'm not sure. seems a little heavy to me.
the nova has been put on a diet:
no back seat
no sound proofing
no heat/ac componets
it is a hatchback
nothing in the trunk except battery
no spare tire
no jack
fan removed from engine
electric fan installed
alum. heads
the scales are there for buses to drive onto so the kids can see how much they weigh
i should go to the scales at the truck stop--they are certified.
maybe next week

A real good friend of mine has built 3 of the 355 combo that you have or very close to it. The last one was in a 69 Nova I'm not real sure of the weight but I do know it was all steel no Fiberglass but he put Lexan windows in it. 373 Gears and a 3500 stall and that car ran the best of a 6.70 at 102.98 in the eighth. I am having him build me one as well for my 73 Nova.
