What do you guys think?
Well. I just wanted to run by everyone what I have purchased to throw in my car so far. I am wondering if any of you have opinions on the setup thus far. I dont really plan on racing my car around. It will be a daily driver that I just want to enjoy driving.
So far I have
Crane powermax 2040 cam part number 114132
dart iron eagle 180 cc heads
edelbrock 2101 intake
stock carb
hooker comp headers leading to true duel flow master setup
I plan on changing my gears to either 3.73 or 4.10 in the near future as well. Thanks for your time.

I think thats very reasonable combo. If no problems with the stock carb keep it, Any problems with it..just replace with a Holley SA670..
The 3.73 gear will help you feel the new low end Power. But will affect the cruise on Interstate quite a bit..Youll notice the RPM's at 75mph will be way up.

When I built my Nova a few years ago, I started with a plane jane 307 auto. I painted it, put in a well-warmed up 350 and promptly blew up a couple of turbo 350's. So I put in a Turbo 400 and then I blew up the 10 bolt 3:08 rear end of course.
First I replaced the gears & stuff, stayed with the 10-bolt, but I used 3:23 gears. That car turned out to be a real freeway killer! It was fast as hell off the line and had lots of power.
Then I blew that axle up, and went to a 12-bolt. I wanted and bought, Richmond 4:11 gears for it. Wow what a mistake. Wrong gears for a car with the automatic.
The car completely lost all streetability. I actually sold it a year later. I ran into the guy that bought the car from me about two years after he got it from me. I asked him how my homebuilt 350 and Turbo 400 were holding up. Know what he said?
"Hell the engine and trans are perfect! Havent changed a thing on the car except those damned rear end gears you had in it."
So in one car, you have two owners that both thought the 4:xx series gears were too low for it. Should have used a 3:xx series carrier in that car, and kept the 12-bolt. I'd still have that thing probably ... it ran like a rocket ship and was very pretty to look at. It was a '70 Nova two door.

..... I'm not-sure, but I think the '81s have a one-year-only/computer-run carb & ignition system:
"IF" this is correct, you might need to run an earler-style (pre-'79? ) HEI and carb.....
If the car will never/rarely see the highway-speeds for extended periods of time, and you'll use back-roads and/or stop-and-go driving, the 4.10s will really wake-up the performance, and the 'smiles-per-miles' ratio, too, but it'll drink gasoline by the bucket.....

I dont see why there might be a prob using my stock carb/dist with this setup. It is a pretty mild cam. If anything I should be able t make it by with just getting some bigger jets on the carb if neccessary?

I have the same cam in my motor (H266 is the non-computer version). It gives good low-end torque and I was happy with the 3.55 gears I put in the rear. Of course I like it even better now that I put in the 200-4R trans. I got ok numbers on the chassis dyno of 220RWHP with stock exhaust.
It will be better now that the carb is tuned in better.
