Default Guess I gotta change my signature

Cuz she's got 2 more barrels now!





And my mess of a vacuum steup. Still working on that.



Big change from the way I got it.



I'm not gonna miss that old two-barrel anytime soon.



My detent cable is too short, and I need a new throttle cable, but for now, it's running alot better, start-ups are easier, and I'm hoping the MPG's go up as well.

Very nice. Shoot me your address and I'll send you a pair of chrome valve covers I have laying around. They aren't the best but will match your new intake and aircleaner nicely.

The eBay bug got the better of him, and it sold about a month ago.

His new project is a 73 Chevota Land Cruiser. That's right, a Toyota FJ-40 with a 350 SBC between the fenders. It only improved it's looks

Congrats Clay! Nice conversion. So how does it run now compared to before?

Thanks. Rough at the moment, but that's all in the tuning. I'm having a hard time getting the a/f ratio correct. I'm using the vacuum gauge method, but it's hard to tell what the highest reading is. It hovers around 20 hg, but unless I close the mixture screw all the way (which cause a stall) it doesn't really change.

I've got my timing set to 14* BTDC, and my idle speed is slightly high. I think the throttle cable is holding the throttle arm back, and I have no adjustment left in the cable, so I think a new cable might solve that problem. My fuel level is adjusted, and the choke seems to be operating fine, but I know how to adjust it if it takes too long to warm-up.

My detent cable is too short as well, and it has no adjustment left in it, either. Also, when I pull on it, there is no indication that it is actually operating a switch/lever in the transmission. It feels like it is stuck, and there is a sound from inside the housing that seems like frayed cable pulling back and forth. So I figure a new detent cable is in order as well. So I might as well get a new set of Lokar cables and a Lokar bracket to finish it all off. But that's down the road. I don't really need a kickdown right now (passing gear, mainly) because I'm almost never on the highway.

I have plans on cleaning up the motor and bay, but for now, I'm just tired of the tedious start-ups and bog associated with the 2BBL Rochester. That is solved, and I seem to have alot more top-end, but the low-end seems to have suffered a bit, for some reason. I guess it's all in the tuning.

I bought the carb used, and was told the jets are 78 rear and 72 front. I have no idea as to how this effects my motor, so any ideas as to how close that is to what I need? I don't know what size the squirters are, but the pump cam is red, which I assume is stock.

Any other suggestions are welcome guys!

my only suggestion is to NOT drive the car until the cables operate correctly... you sure don't need to have the throttle stick open while driving


good luck to ya

With stock heads and cam that might be a little rich with a 78 jet as that is the number Chevy puts in the front of the 502 ZZ502 850 carb. But maybe your motor likes it.

What would a symptom be of a jet that is too large?

I feel a bit dumb

I checked the voltage on the wire going to the electric choke, and guess what?

No voltage. Geez, no wonder it's been running so bad.

I re-tuned it a bit today after work, and it's running better, but I can't seem to get the fuel level down in the rear bowl. Clockwise lowers the float, right? Because I must have turned the nut 15-20 rotations, and it's only gone down 1/16-1/8"
And when I loosen the screw, fuel sprays everywhere, which it does not do on the front adjustment nut.

Stuck needle, maybe?
