You guys are making me re-think the Eddy carb now
I appreciate the spread bore suggestions but am set on a square bore.
For you Holley fans which model would you recommend?
Churchkey and Mr55/56 suggested this one.https://www.amazon.com/Holley-0-1850...gateway&sr=8-2

What about this one?https://www.summitracing.com/int/par...0-vs/overview/
I will be ordering from Summit so I am shopping from their site.Thanks to all that have replied so far!

Your links came up Demon

IMO, Holley, order manual choke and pin it open unless you drive in freezing weather !

Demon is touted as a good carb but is it 200 bux better than a 1850? IDK never ran one I like 1850 Holley's for street cruisers 1860's for track. Used to get my track carbs from Barry Grant he is no longer in business.
Whatever you get you will need to change the jets the linked Demon will be very rich for your 283. I run an 1850 manual choke on a 355 & currently have 62 jets in the primary down from 66 @ start up. Secondary = no fuss it has a metering plate. They are available with an E choke.
Your $$ your call.
Good luck

1850 Advantages include cheaper.
It is square bore so you can upgrade later.

650 DP Advantages include (IMO) better value, it will feed up to 425 HP, should you upgrade. Includes dual feed, second accelerator pump circuit 100% go when you mash da gas, second metering block so you can tune for your needs, for $135, you can get HP main body with down leg boosters and choke tower delete.

Hey guys,just thought I would update this thread.I went with the AVS2 650,Air Gap manifold and 4 hole 1/2" spacer,Lokar throttle pedal and cable.Installed everything and was surprised I had no leaks and it pretty much fired right up!
Took it out for a quick test run and it ran real well.I still have some fine tuning to do with the throttle cable but at least it runs and drives.I still need to tweak a few thing like lines and hoses and I will be doing a plug chop soon to see how much tuning I need to do to the carb.I did buy the tuning kit so this should be straight forward.I want to thank everyone on this thread for their advice and encouragement.
Couple of pics...
1.What I started with.
2.Inspector.Always there making sure I do things properly.
3.Intake and carb installed.
4.Assembled and running.
5.Finally out of the garage!

This is comparable to the replacement I'm getting for my 327ci, 335hp with a moderate Lunati Voodoo cam. I don't want to pirate into OP's thread, but I wondered if the 650cfm was more than I needed. I think a 600cfm would have been OK, but I don't think the extra 50cfm will hurt it.

I'm not a hot rodder so I don't know the advantage of a high riser manifold. I do know that hot air at the intake is not good except in cold temps, so what I did with the intake manifold was to use gaskets that blocked off the center ports going to the crossover..

Nice looking change in the engine bay ,clean looking car as well.

Noticed the plastic inline fuel filter. Never been a fan of those they tend to crack or leak at the seams over time given the heat in there and result could be FIRE. Better off with a metal canister style

As long as you stay with vacuum secondaries you should be ok.
