Not a "hot rod" but my daily driver.
81 chevy K-10, new GM 350 crate motor edelbrock performer intake, headers, dual exhaust. Current carb is an edelbrock performer #1405 it worked good on the old 305 but I think I can do better on the new motor.
Been looking/thinking Holley, demon, Q-jet
Any suggestions??? Like I said, daily driver, work truck, does some 4 wheelin' but mostly to get to and from work sites nothing extreme. It does tow a 4400# travel trailer on occassion.
Thanks

My $.02 would be to stick with the Edelbrock unless it's a fudball giving you trouble. Many believe that a Holley will give them instant massive improvement and are disappointed. That 1405 is a nice solid carb and easy to work on if necessary.

The edekbrock is a good carb for it's intended use. I daily drive in elevations ranging 3000 to 8000ft sea level. Took me 2 weeks to get it adjusted when it was on the 305 so it ran ok all the time. Having to start over again really does not appeal to me not to mention I don't have 2 spare hours much less weeks right now. Last time the final combination was no where near to being what the book said or what edelbrock suggested so it is all trail and error. VERY time consuming.

Sounds to me like fuel injection would be perfect for you. Getting ANY carb dialed in in those elevation extremes would be tough.
I'm running a 1406 on a mild 351 W, and it was "plug and play"........ of course, I dont have any changes in elevation like you do.
Look at the Edelbrock and Holley F.I. systems. Pricey, but nice. Good luck whatever you decide!

I think Id use a Q-jet personally

if you have a spread bore intake you will need a spread bore carb, unless you use a adapter

The performer intake accepts both square & spread bore applications

The Performer does accept both style of flanges.

I woud use a Q-jet. It would be nice if you could find one of the 1900 series of Edelbrock Q-jets on a shelf somewhere. I have a 1910 and I have to do a little tuning berfore next season (playing with the secondaries). Otherwise a rebuilt Q-jet would be nice. I would contact a company like Jet and inquire about jetting for your elevation. If you go junkyarding for a Q-jet and you happen to find a bunch, pull them apart and take the primary jets and rods, the secondary rod hanger and the secondary rods. All nice parts to have for tuning. plus pulling a few apart will show you what you are up against when you rebuild your keeper.

Appreciate all the help folks.
Still looking though I have managed to get the edelbrock running to about 95% PERFECT still have a little playing to do to see if I can get it better still.

I bought my Rochester Q-Jet from this guy for under $200. You might want to check him out.
