    Paul. The mystery is that there are no joints, it is one continuous piece of wire from voltage reducer panel to instrument cluster. Came off a spool of 16 gauge automotive wire (50 volt rated fuel resistant etc.) and only thing different than other places that same wire is used is the antifreeze leak last year was in the vacinity. Even a mystery there, the wire is coming out of a loom above the panel and hanging down to go into the lowest terminal of the panel so if it was antifreeze it would have had to wick it's way 3 inches or so UP the wire to do that damage. Here is a picture of the panel with the rotted wire sticking out.

    Here is a picture during installation and before shakedown showing the heater and AC connections above panel. The dripping on the carpet that led me to the problem did bleach out some of the carpet color (had to restore) but even more mysterious, that spot was to the left of the end of the perf cage around the circuitry.

    And finally here is a shot of the car show that we missed out on (wife and I drove over there in suv later in the afternoon when I knew I had the problem fixed) with lots of the cars already gone. Looks like it would have been good fun.

    Stopped over to see what new projects the Kings were working on today and decided to take a picture of a roof they were repairing for another restorer and noticed an old 'rust bucket' on the left.

    Got a better picture of that one - a rather rare 39 Chevrolet wagon.

    Will be interesting to see them bring that one back to life.

    Guess the years are catching up with me. The Hushpower II mufflers are sounding louder and louder as the seasons move on. I have been listening to all the sound prints I can find for other mufflers but the field is spotty to say the least and most 'performance' gu ys indicate that their mufflers sound different on each engine and sometimes also with different exhaust configurations. Do any of you have experience with Borla ProXS series? The Borla rep acknowledged that they do not have a published sound print for those on any engines, but indicated that they are very similar to their touring series sound. Seems like the Corvette guys and the Mustang guys are split between the ProXS being 'too quiet' and just right. I would like to get rid of the head pounding drone of the Hushpower's in the 40 to 50 mph range and so far it would seem that the Borla's are a reasonable move, I only wish there were some more certain way to anticipate the results. Appreciate any input that any of you care to make. Bob front under to back.jpg

    Finally found enough sound prints to determine that the Borla parts would have done the job, but the Thrush Turbo's would do it even better for a lot less money. Have worked out installation based on measurements of spacing available and optimized for all welding on bench with only four clamp connections required. Changed the plan to provide 2.5" pass thru to muffler where current arrangement has two step downs (header collector 3" to 2.5" and reducer 2.5" to 2.25") on way to muffler. That will hopefully make up for some of the power loss incurred by changing from straight thru to offset passage exhaust build r4.jpg muffler design.
     
  6. Oh, and I don't see a cross pipe.. that will smooth out the sound. Before I did the final fitment, I capped the crossover and cranked her up and I didn't like the sound at all... I sensed more of a "sharp" sound without the crossover.. and very noticeable difference...

    Please don't mind the shitty welding.... HF $99 welder.. but still works to a certain extent... ahahha

    Thanks for the feedback Paul. I did consider a crossover but there are some logistics that I don't like with doing a cross over so I am going to try this without. I did see a lot of chatter that a crossover does just what you say (smooth out and equalize the sound) but if this doesn't work then I will consider that for the next car. Best regards, bob
     
  8. Looking at your picture of the underside of your car (I'm just guessing that's Flashback, and your drawing)... what if you moved your mufflers back further toward the rear of the car, then you might have room to get that crossover behind the transmission.. ??? just a little bit of cuttin' and weldin'.....Also, no electric cutouts ???? .. DANG.. I couldn't live without them.. but that's just me (when I feel like showing off..ahahah.. which is alllllllll the time).. you may have noticed that I had NO ROOM for fixing my cutout issue even after it was all complete, but I jacked her up and cut the exhaust system out and did it over, just like your avatar comment.... hahahah..

    Just a short story now.. when I was building the chassis, an old friend of mine was sitting there drinkin' beer most of the time contributing NOTHING but criticisms........as I was pondering whether it was worth another $350 (the best I can remember).... he said "If you don't buy them and putting them in now, you are going to end up pissed at yourself".....I never did like to be pissed at myself, so I ordered the dang things that afternoon..... what the heck is money anyway.. can't take it with ya !!! Hope you are having some decent weather these days...

    Paul. due to the extra length of the 700R4 the crossover would have to be after the frame crossmember which also means there would be no tunnel clearance to work with either. I will get another look at the situation next week and see if there is anything that I missed in the original thoughts of putting a crossover in. I don't have a lift to put the car on so I have been blocking it up and then getting under to see clearances with full load on springs. Seems like it takes a lot more effort to scoot around nowadays.! Will try to take some pictures to show my concerns. Have a good week.
     
  10. I surely know what ya mean about "jacking her up" and trying to crawl underneath.. same here.. only in the last couple of years have things gotten a lot harder to do, it seems.... take another look closely at the pics in the link I posted about my cutouts...since we both have 700R4's my configuration should be pretty close to yours.. I used a Camaro crossmember that looks like yours.........Don't know what you mean by tunnel clearance.. it would go across somewhere under the tailshaft.. and if you use clamps it's loooots easier to deal with.. doesn't seem as if you looked, unless you are wearing "protection".... hahahah.. I have a "tracker" on the website...that shows where folks are that visit my site and which pics they click on...

    And I use Duck Duck Go for lots of searches so that no traces are left behind.
