Hello BWDart.
I have a customer with a mostly stock 340 4 speed duster.
Due to limited funds on his part we installed a re manufactured Edelbrock carburetor back in March of this year and other then changing jets and rods to fine tune it have had no issues.
Down side is that Edelbrock warranties the re manufactured for 1 month compared to 12 for new.
Up side was he saved over a hundred dollars buying it from Edelbrock directly over a new one.
If not for having REMAIN stamped on it I really could not tell the difference between it and new.
I know Summit and Jegs both sell re manufactured with the same terms and conditions but at different prices.
Hope this helps,
Happy Mopar :
Arron.
