1973 360 upgrades

I’m hoping I will see some noticeable gains going to a 4 barrel….. and a good intake. I may do a cam swap soon also but I need to make sure I can do that.
I may also have the gears changed but I wanna see what’s in it first it does have a suregrip. I’m sure a 3.90 or 4.10 gear may help it???
What intake did u run on your truck? I’m thinking about like a Soeedmaster air gap clone but am getting mixed reviews…….

Another really good and overlooked intake is the Holley Street Dominator. Even though it's a single plane, its design gives up nothing on the bottom end, because of its huge plenum. They pop up here and on Ebay from time to time. Since they are only available used, make sure if you get one it has not been ported or modified.
