Foxy Green Foxbody Build

850 bare minimum or 950.

Reasons I heard were a 427 is going to have so much low end torque it won't matter, dual plane is a piece of shit, small 210 heads...

Well the fuckin thing barely breaks the tires loose and pulls like a ford suv. Try again, this time start with a smaller number on the shifter ball and a bigger number on the tachometer.

So what do you blame first.

Heads
Cam
Intake
Carburetor
Tuner :lmao:

Did you get the timing sorted out? If its low it’ll be a dog

Who knows. Can you judge the timing off a plug that's mostly cruising and a couple WOT pulls?

No vac advance, I'm all in 32 degrees and the timing mark still looks low on the strap below the apex

 
If you have 32* in by 3-3500,should be fine. How much run time on that plug? Maybe it's a dog down low because it's lean. I have 2 1000 cfm 4 barrel TBs on the model A and it pulls hard right from idle.

The slowest curve I can give it had it all in by 2500rpm.

Only 13 miles on that plug down some back roads and about 2 miles of in town traffic. About 35 minutes run time if I had to estimate.

The a/f gauge shows rich everywhere except when it breaks up and pings at lightest of throttle trying to maintain mph on flat ground and spikes the a/f gauges.

The WOT 2nd gear pull (10.7 afr) roughly 2k to 6k didn't really feel all that fast. Grabbed third and i still wasn't impressed.

I was in a 2006 gt500 when they first came out and that car scared the piss out of me when you rolled into the throttle.

My ford edge put me in the seat harder than whatever this is, which feels impossible with this many cubic inches. Something isn't right and I'm tempted to run compression and leak down tests or something

Does the carb open all the way? (I'm only being partly sarcastic. Seriously, look for stupid stuff out of order. Lots of smart people trip over stupid stuff)

Timing looks ok to me but I'm no expert, but damn does that look clean for the driving you explained. Again, no expert. Also, really need to cut threads off or use an ear doctor light to look down low on porcelain for brown ring. Did you try 28° etc
 
The 850cfm on it's own, won't be the issue. It could be that carb but not the fact it's 850cfm. I have a 750 on my 314ci V8 that people will say is too big but it has no problems turning the tyres and if driven normally, drives near as good as my 6.0 LS daily. Earlier this year I did a couple hundred mile trip over the mountains with a loaded utility trailer hooked to it, it just doesn't care. With me in it, it weighs ~ 3600 lbs and has done a best of 12.9 on street tyres with a dismal 1.9xx 60ft. Slow compared to most here but that supposedly huge 750 carb just works.

You have over 100 cubes on me, you should have no issue getting it sorted with anything decent from 750 to 950 cfm.

Not a bad idea at all. Have your future stepson step on the gas while you look down the carb and see what's up (not running, of course).

It would be great if the folks suggesting this solution are spot on.
 
Just in case anybody else thought Foxy must have died, he showed up on YB last night asking questions. Looks like his intake is still sucking oil.
 
I've given up on this forum after it turned into bans and censorship when words hurt.

I went to the new place, if you weren't invited pm me.

If you have IG you can see my non-car antics and videos of dickless @the_spotty_pippin
 
Does anybody know what this new place is?
He's posting over on YB again today, but he cant think YB is new.
