Foxy Green Foxbody Build

All those companies are, each and every one of them will need some sort of adjustment for each application, just part of the game.

Agree. But bottoming out the acc pump and not being able to adjust that out is a major oversight. The cam must be wrong for the application, or installed wrong and not checked for travel. That's not something you leave for the user to find and fix.

I know most say not to bend the arm but in this case I think that bending the arm is the only way to correct it

 

[Badd_Dadd]

Well if you don't have the car running after carb fiddlefuking, get idle speed set, THEN work on pump cam and lever.
You don't yet know throttle shaft position at idle yet.?
Thus what came first.

I set my Holly's just a little lose but not lose enough to get a boog

I tried to set the carb up on the table before installing it today. I have external adjustment for primary and secondary idle. Squared up the slots on both sides. Both screws adjust the blades evenly so if I need adjustments I can hit both to keep it even

She made a couple pops when i hit the go button. Scoots right to 60psi oil pressure. Jomar 100% no bypass oil filter. 10w40.

Gonna roll her into the alleyway and make some real fuckin noise after church tomorrow. Timing isn't right at the moment. I have vacuum ports all plugged right now to try and start fresh on everything.

Leave the primaries square and use the secondaries for idle speed adjustment. The primary side is more critical.

The only reason I don't like that idea on a dual plane is at light throttle the secondaries are basically closed because my idle was set around 750rpm

My (probably incorrect) theory is that at a light cruise it would help with fuel distribution in the dual plane if the primary and secondary are both allowing fuel to be pulled into the intake somewhat evenly, especially with the annular boosters

Correct.

 

[Badd_Dadd]

Correct, regardless of dual or single plane.

Or you could get that 650 you want.

 

[89 Fox 427]

Already have one!

 

[Steve439]

Already have one!

It would be interesting to get the 850 sorted out and then put the 650 on and sort it out.

A 1966 427/390 Corvette came from the factory with a 585.
That's what the engineers thought made for a good street carb.
If one plays around with RPM and VE in the CFM formula a 585 is probably about right.

Something that I never see mentioned with this calculating is the fact that an engine will drop some amount of VE between peak torque and peak horsepower.

Pippin is up 0.8lbs in the last 10 days. Given that she didn't eat for 40 hours after her surgery 7 days ago, I'd say I'm pretty fuckin pumped about it.

At light cruise the secondary boosters aren't doing anything on a correctly set up carb (assuming it has a progressive linkage). If you're using enough throttle input to be at a point where the secondaries are opening, you're past the light cruise stage.

Try it both ways and see what works.

I guess maybe I'm not understanding you. If I adjust idle with secondary screw, I lose the transition slot and the engine is only pulling from Primaries until I lay into the throttle pretty good. At least I think my terminology is correct.

I'd say where's Waldo but that's pretty obvious..

That thing stands out like a nigger at a KKK rally.

Have fun!

I am probably up 0.8bs in the last 10 days too.

I hope it's not one of your neighbors cat under your next door neighbors right rear tire.

These lifters are silent.

I turn the coil off and crank until I see oil pressure, then light it off.

Except I forgot to turn the coil on for a second there. I have to go to work, but when I return this evening I will give you guys all the info of what I found after getting her warmed up. I'll need some help evaluating

85 humid ass degrees out there.

First Start After New Johnson Lifters

I turn the coil off and crank until I see oil pressure, then fire it off. Except I forgot to turn coil back on for a second there.
