I think the old Owners Manuals said no quick starts for at least the first 500 miles. This topic has all kinds of answers. Some say drive like you normally would and don't worry about anything. I personally would drive it fairly easily for the first 500 and then unleash the beast!

Btw, nice fuel line wrapping around the thermostat housing, WTF. Fix that thing asap and drop that see through filter. Also attach that top radiator hose to the fan shroud before the fan belt eats a hole in it from bouncing around.

Other than that grats on your new engine.

I'm currently breaking in my refreshed 425. I was told to try not to keep a constant speed, wind it up from stop sign to stop sign, tramp on it from about 50 mph to about 70 mph. The guys I talked to said that I had to, 'set the rings'.

I don't know how true that advice is but I'm havin' fun!

The thing where the fuel line goes on the wrong side of the thermostat housing, stops short, and converts to rubber hose with an aftermarket fuel filter on it.
I'll bet you money that that steel line has no retaining ridge on it to hold the hose clamp and the rubber line, so the line can just be pushed off by pump pressure (or the rubber hose can rupture), pouring gas onto your engine, and causing this:



Do people get away with rubber hose and cheap aftermarket fuel filters after the fuel pump? Yes.

Do you want to take that risk with your new engine? You decide.
