Re: Holley spread bore carb.
Why wouldn't they be? It's a Holley so all Holley tuning tricks & parts apply. The rear metering plate can be replaced with a metering block, the vacuum secondary springs can be changed, jets can be changed, cams, etc., all in the name of tuning for performance or mileage.

Re: Holley spread bore carb.
I'm not sure the Holley spread bore is a direct bolt-on for a 351C factory Autolite 4bbl intake. I think it needs an adapter. Been a while since I've messed with 351's....

Re: Holley spread bore carb.
I know the 1973 and newer Autolite is a spreadbore but I'm pretty sure the bolt pattern for the four studs is something weird. But there are adaptors available.
