Time to buy the rest of the things Ill need to install and tune my 700cfm Double Pumper.

Manual Choke Cable

Dual Feed Fuel Line. Whats the standard size, 8-21/32" centers? (i dont even know what that means)

Jet Kit, 2 each 70-80. (66,76 stock in carb already)

I want to have it tuned near perfect (getting help from a guy whos familiar with tuning Holleys) so I want to install an Air/Fuel gauge. I need a cheap one. My Flowtech headers already have a bung in one of them, just need to drill a hole. What gauge should I get?

Do I need a vacuum gauge to determine the best size powervalve? I know I dont get much vacuum with my 234/242 cam.

Let me know if theres other things I should buy. Im going to Pace Performance to get this stuff, or Summit if Pace is out of stock like they often are.

 

Get a dual feed line for a 4150 style carb. Or an adjustable. "Center-to-center" means the distance between the centers of the fuel bowl inlets.

What are you doing for the fuel pump?

 

fuel pump is still the stock electric in tank. Not changing it at this time. Using the Mallory AFPR with rubber hose crossing over to the other side of the carb, but might switch to braided steel AN fittings later

 

Limiting the length of the rubber is a very good idea, especially if you would like to make a run with it at a NHRA-sanctioned track.

I've never used one, but I understand the cheap A/F meters aren't good for much. Wide-band much more useful. Vacuum gage cheap and very useful.

 

I just talked to the guy whos gonna help me tune it. He said not to bother with an Air/fuel gauge. He can do it by smell/feel. That helps my wallet, now I can get the braided steel fuel line.

Should I buy the powervalve blowout protection kit?
