What carb's are people running on the 525sc's (454 with the small blowers) other than the factor 1050 dominators and what kind of improvements did they make?

I think the Hawk motors (454cid, 177, 525hp) in Cigs use a reworked 850 holley, made to flow 900+cfm. It supposed to give them a better idle.

I think mercs 525 was the 1050 dom with the bm blower

Stock 525sc's have the 1050's. I don't know how you could make them idle better. Mine idles like its an efi at 700rpms in gear.

Tyler Crockett set some up for me that were perfect and a great deal. They were modified 850 Quick Fuels. The guy who owns Q.F. is my neighbor, an ex Holley guy. I beleive they were in the 400's range but I bought a lot of other stuff too. The motors ran like EFI.

I agree with that. The only thing that would be better with the 1050's is if they had a choke for those cold fall mornings

love my nickerson I bought this fall, but it takes like 8 to 10 mins to warm up other wise it stalls. hope its just the cold.

8-10 minutes

I can let mine run @ 1200rpms for 30 seconds and back it off the trailer. Its close to stalling then, but after another minute at 1200rpms its fine.

Mine idles and runs fine. I just thought that a 1050 is a little much for what boost these little motors make. I was looking at a 850 Barry Grant demon or even a pro systems dominator or something that would give better fuel economy and speed. I thought I would ask considering how many people are a member of this board. Somebody has had 525sc and tried everything I am considering changing from heads ,cams, to carbs.
