 Topic: 401 CarbPosted: Jun/09/2012 at 11:37am |

Growing up in the snow of Wisconsin I learned very early steering with the rear end. With this Javelin it sure is a blast "occasionally" gettin loose. As for the Carb I'm going to start with the vacuum secondary 750, I'll get the 50cc accelerator pump kit and go from there. I'll play around with jets and Discharge nozzles. If I don't think that's enough I'll go to the double pumper. I think the modular design of the Holley is going to make it easy to tune for the application.

Learn to steer with the rear end. It will add a smile to your face almost as fast as a naked pretty woman.

I have the Eddy 800 AVS on the SC/Rumbler sitting on a Torker with pretty heavily street/strip ported big chamber heads using SpeedPro forged pistons and the 8601 cam big tube ceramic coated headers. The car literally has too much power to the point that I always have to be careful so as to not have it always going sideways in the first three gears. |

How about using the Edelbrock AirGap with their AVS 800 cfm carb? They are made for each other and will work great with your cam and 3.54 gears. Since your red line is going to be 6,500 rpm for a street car your rpm range is going to be between 1,500 and 6,500 rpm with your peak torque around 5,400 rpm. Torque is what makes a car really dance on the street and the AirGap/AVS 800 will make more power than your tires are going to know what to do with. I am running this combo on my 70 390 AMX and I love it. I gasket matched the intake to the heads and I am running the AVS carb right out of the box with just the normal external adjustments. I bought the one with the electric choke and I am using one of the stock choke covers off of one of my old AMC Carter AFB'.

Good call. I guess I was just wondering what people are using on AMC engines.

why not ask Lunati what they think you should use?

I wont be in the highway a lot but I do want to keep it reasonable. I want to be able to drive it to shows and might travel a bit to get there. How do you like the Torker? I'm looking at the Torker II myself. The cam on my list is a Lunati Voodoo Hydraulic flat tappet. (234/242 @.050, .547/.569 lift) I'm trying to find the right Carb for the combo.

that's not true I have a 850 speed demon that I put on when I go to the track and a holley HP750 that i use on the street and neither 1 of them have the choke set up on them the tops of the carbs are all milled nice and smooth I drive my car in the winter months and have no problem starting it with no choke. If the timing is right it shouldn't backfire at all |

They're not the best highway gear. I don't do a lot of highway driving with the Rambler but the few times I did I could hang with the slower traffic and keep the RPMs reasonable. I'd stay with the 3:55's if you're going to be on the highway a lot.

I've also read that the carbs without chokes are dangerous and like to backfire. Anyone had that happen or heard of that?
