    PVCR Calculation for Six Pack

    On a related note - I installed a bypass style fuel pressure regulator and it made a big difference in driveability. I use a mechanical pump with plenty of output volume and the regulator bypasses the extra back to the tank. Keeps the fuel a lot cooler and performance is more consistent over...

    PVCR Calculation for Six Pack

    I agree this is something that may not warrant my attention. For a square bore Holley carburetor, a general starting point for jetting (secondary versus primary) assumes the airflow rate through the secondary and primary barrels to be the same at WOT. Roughly speaking, then, you would want the...

    PVCR Calculation for Six Pack

    Hello, Running a six pack setup, I am a little uncertain on how to compute/estimate my PVCR size. I am familiar with the formula that adds the area of the primary jet to the area of the PVCR to arrive at the suggested area of the secondary jet. The fly in the ointment here is that I am not...

    Secondary Metering Plates

    Lewtot184, Thanks - your explanation for the stiffener plate makes sense. I can see how the gasket could, especially over time, swell or shrink.

    Secondary Metering Plates

    Hello all, I've been slowly refining the tune on my six pack setup on a 493 stroker big block. My question has to do with secondary metering plates. I came across a pair of secondary metering plates that accept screw-in jets, but they don't fit properly. They tend to interfere with the...

    Automatic Console Shifter

    Wow that looks great. If you remove the console to replace carpet I would appreciate some photos. What did you have to do to the factory shifter bracketry? Thanks!

    Automatic Console Shifter

    Folks, I have a '68 B body with the stock auto shifter mounted in the center console. Just wondering if anybody has replaced this shifter with an aftermarket unit and mated it to the console. The factory shifter has several pivot points = places for slop in the linkage. I might consider...

    Borgeson Update

    The cooler did the trick. No issues with assist fading after use, and the fluid stays cooler. I used a Derale cooler P/N 13309. Inexpensive, compact, and it does the job. Comes with AN6 fittings installed. BTW I have not noticed any strange noises (hissing, etc) coming from my Borgeson...

    Cold Case Radiator Hose Size Mismatch

    Hello all, I am using a Cold Case radiator to cool my 493 stroker - works very well BTW. The lower hose is a loose fit on the radiator. The radiator OD is 1 5/8", but the hose ID is 1 3/4". When I bought the radiator I called Cold Case and they indicated the radiator was correct for the...

    Check my carb tune please?

    Check my carb tune please?

    JerseyJoe, I went through a similar exercise using a Promax metering block on my six pack setup. Reduced the screw-in IFR's down to 0.028" and it made a big difference in cruise AFR. Just a suggestion, however, on seating those IFR jets - I noticed mine (like yours) sat nearly flush with the...

    Borgeson Update

    Hello all, Just a month or so ago I installed a Borgeson power steering box in my '68 B-body. I retained the existing Saginaw power steering pump. The other day the weather allowed me to take it out on an extended cruise up and down a local mountain highway. The steering feel was more...

    Starter Question

    I had exactly the same issue. For a while it would turn over a bit lazy, then one day it would just click. I suspected some sort of mechanical misalignment at the starter as well, but that was not the issue. I put a voltmeter on the starter "hot" terminal, turned the key, and observed a...

    Six Pack Fuel Slosh?

    Hey I know it has been a long time since this thread was active but I thought I would post an update. In general, I have been slowly tinkering with this setup to improve driveability. On the subject of fuel slosh, I found that the reason for this behavior was the center carb metering block...

    Borgeson Power Steering Report

    Folks, I just finished installing my new Borgeson power steering box + coupler. I was running a Firm Feel stage II box, which I removed due to a leaking seal. Bottom line - I like the Borgeson unit better. A bit less assist at low speeds, but more precise at speed. There is no on-center...

    Power Steering Box Leak

    Victory! Almost. Got the old steering box out and all the new stuff in. Maybe some of the following will help somebody else thinking of swapping out their stock box for a Borgeson setup. Note this surgery was done on a '68 B-body, 440 with TTI headers and a mini starter. Getting the old box...
