70 L78 Nova..
Since you are asking questions about correct install of engine items...couldn't help but notice your throttle spring placement. The factory install would have been completely different...also I see a vacuum hose connected to a port near the air-horn on the carburetor...can't quite see where it goes, but it looks like it is running to the distributor vacuum advance ?? If so, this will not give you the correct vacuum source for the advance.
Not sure what level of 'correctness' you are after...but, we can post some photos as a reference if you want. How about posting a few photos of your car...we love pictures  -wilma

"a vacuum hose connected to a port near the air-horn on the carburetor"
Yes, this is the vacuum advance hose. Thanks to yourself and other Super Car registry users I know I don't have the complete and whole TCS solenoid and set-up, but obtaining these components is not a priority step right now and is on the futures list. When I installed the 4557 carb, it was different from the pre-existing carb, and since I'm not a mechanic it appeared to need a vacuum hose in that location, so that's where I have it right now. So, if I tee the hose elsewhere I'm assuming that port by the air horn should be stoppered? If the throttle spring set-up is wrong I would like to address that with a reference and a supplier of the correct spring kit. Many Thanks Last edited by Diamond_Don; 09-07-2017 at 06:36 PM.
