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
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.
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.
