What have you done to your square lately??

[DoubleDingo]

I agree. Somehow, even though I have a degree in Mechanical Engineering, reading manuals or even looking at diagrams about carbs makes my eyes glaze over.

The linkage has a couple tiny studs on the end to keep it on the cam, it looks like I have to un-hook the tiny cotter pin from the other end, pull that end out, so I can rotate the thing 90deg to slip it through that curved slot. Then re-attach the lower end.

Notice you didn't actually say *what it is*, just where stick it in... ;-}

Linkage rod?

Here's what I did to my square lately...I attempted to make a spirited 1/4 mile run in a fairly remote area. After stomping the go pedal, the truck suddenly went to idle only. Well, I ripped the Lokar throttle cable out of the ferrule on the throttle body of my First fuel injection intake. Clearly due to my gas pedal not being adjusted properly. I was just barely able to get a couple strands of cable into the ferrule to limp all the way home. I was half considering making a shoe string throttle haha. Good times.

Wait, you have a FIRST intake? As in, TPI? If so, how do you like the setup? Did you buy it new or used?

Bought it new, and it's AWESOME, in my opinion. When I first frame-off built my truck in the early 90's in high school, I put a 350 TPI out of an IROC in it, with an Accel computer. That was kinda high tech at the time. The truck sat and rotted from around 2001 to 2012. Spent the last 12 years doing it all over again, but better. I wanted TPI because that's what it was the first time I built it, but that intake can't breath past about 4K rpm. And no way I was LS swapping it, had to keep to it's roots. So I bought the FIRST intake and put it on a new roller crate Vortec 350 (the SP350/357 to be exact) with a Holley HP ECU, and it does everything I want it to do. It's TPI as GM should have made it, all the torque and it can rev pretty good too. I keep saying I need to make a build thread.

Don't judge the pic too hard, things are cleaned up since taking it. Still need to route a cold air intake though.

Love it man! I have a standard tpi with a voretec lower I'm going to put on mine soon an run with a terminator.

When I do my 383 I have a super ram with the tpis lower.

I love it when I find an easy solution to a problem…the lower rad hose “leak” I thought I had turned out to be operator error- I thought I’d tightened the radiator cap but it still had another couple mm to go before it stopped. I found the bottom lip of the cap a little damp, and I just needed to give it a little more oomph. It was leaking inconspicuously down the side and leaking out on the bottom of the hose. I love an easy “D’oh” moment and one less thing to do.

Wow we are back in the mid 90's with all this TPI talk. There was group of us with Camaros that ran all around the Houston area street racing. We all built them differently. One was a Accel super ram, one was a SLP type ( I can't remember the name), I had the Arizona speed and marine runners with a ported GM bottom and plenum. They all had 58 mm T- bodies, different headers, 700R's with converters. I ran a best of 13.2 with the stock heads and cam. I graduated to a 383 and a TPIS Mini Ram before the car got stolen. We would run 3 wide on Westheimer road. We also ran out on 10 west.

I picked up my 350 SB at the machinists shop (#1), and took it to machinists shop (#2). Number 1 is going out of business and laid off everybody with zero notice. "pack up and get out" he told em. One guy had been there for 24 years. My Friend,Bob, who was doing all the work on my engine is shop #2 and he will help me build the final kit that I will assemble into the finished engine. Bob has lost his lease twice recently which is why his new shop is not really up and running. He was using income at shop 1 to survive till his new shop was ready. So we will press in a new liner into one cylinder, do all the needed machine work left, and then I will take over and assemble. I expect this to take a year or two. Then, the engine will go into my 81 "Ralph". I'm going to need a 4 speed to go behind this engine. and fuel injection? maybe and and and..

Was bummed about the Dawgs losing to the elephant tide but I'm a C Tigers fan so...see you later?

Teams getting into the postseason for several years in a row...that can make teams complacent. Just saw the Astros drop two to the Tigers; they haven't been in October baseball for ten years, we have been for eight straight seasons. Oh well, were we in the playoffs, my brother's Wednesday night gig would have been cancelled anytime there was a game. So better for us ....

The piece you have to connect it to is the choke pull-off. It gives a restriction to the secondaries and choke opening while there is a high vacuum in the manifold(idle). When you floor it and the vacuum falls off, it lets the gold arm extend and allows the secondaries to open slowly instead of slamming open. You are correct on how to connect it, or you can unbolt the pull-off and rotate that to slide the rod in the slot.
