Stock 360 Upgrades for Crusher Cuda?

Oh, switch to a 904 now if you can. If not possible, no worries.
Do NOT use a single plane intake!
DO USE the Edelbrock RPM. Also use the heat insulated gasket under the carb. More so important for the Edelbrock style carb.
To keep everything under the hood, you’ll need a drop base air cleaner. Order a filter that gives the most clearance over the crab and not interfere with the hood. Clay is good to use.

I like the FBO ignition. A stock distributor will do great if recurved to suite. (4secondsflat.com, you can get an entire system there in one shot.)
Do! Install a windage tray.
Thank f you can weld in hour own oil pan baffle, do so.
Main studs are not needed. Re use or purchase new bolts, you’ll be good there.
