Oh no doubt, they can be a pain to work on, but you forget all about that, once you have them running, & can go out on a drive with them. I recently installed NOS Updraft carb.'s, on my '53 Chevy COE, & my '52 GMC 450 COE. The Zenith Updraft, on the 450, is larger, & heavier, than the one on the 350 COE. Can't wait to see pictures of yours. Here are my Webshots,
