This is the carb i got whit the engine..im missing the uper part of the box...can sombody tell me is this the right carb.the nubers on the coak horn are 80486...and1085..thank you guys

Ayuh,.... No idea what yer motor, 'n drive are, so no idea if it's the right carb,....

The box is for a turbocharged blow-thru application,....
So, if you don't have forced induction, you don't need the box,....

502 cheavy all stock.with a m-1 procharger kit..

I'd check the list number again on the choke horn. On marine carbs it will be that 5 digit number but you must be a digit off cause that number doesnt exist.

It should work if it is bigger than 700 cfm I could not find a listing for it just keep a eye on your air fuel ratio numbers how are you altering your fuel pressure under boost.

That looks like its a carb off of an HP500. 800cfm 9022 carb

i'll whatc aut for that...thank you

Here is my chocke horn if you magnifie you'l see the nubers...thank you

Does that fuel pump generate enough pressure to be used under boost conditions

fuel pump makes 9 psi and my boost is going to be around 5 psi
