  1. Fitting TKO600 in 70 Mach

    I would think to fit a chi you probably want to drop the motor and keep the engine at a very goodangle. Or it will be tough to fit an air cleaner due to the angle. Unless your putting a big scoop on the car.
  2. Fitting TKO600 in 70 Mach

    i went full size case. i had to do a few small tunnel mods, used engine drop mounts and made my own crossmember to keep the trans tail as high as possible. i'm assuming you aren't running a shaker?
  3. Long Tube Headers?

    mach1 driver. keep in mind, behind where that collector flange is, the transmission crossmember and associated floor support is there. that will limit how far up into the car the tubes can tuck. the factory crossmember setups had sort of a v-shape in an area close to the transmission that allows the exhaust to tuck up tighter. However a difficulty can be that it's closer to the transmission and the FPA's want to exit close to those floor supports on the sides (plus the FPAs don't angle much at all to point them towards the driveshaft area).
  4. Stinky gas smell

    I had noticed the fuel in the bowls wasn't visible when looking into the glass sites after a period of time. I had assumed it was evaporating out. Likely at a much higher rate after driving due to heat soak, then tapering from there. Fuel smell wasn't something that I used to pay much attention to because it wasn't noticable after an evening or so. And that smell is probably more just the carbon monoxide from pulling into the garage.
  5. Stinky gas smell

    an EFI fuel tank can get warm/hot (assuming a return system). I'm still running a carb but do have an electric pump. I shut the pump off when i'm getting close to home to try and reduce the amount of fuel left to sit and evaporate out of the bowls.
  6. Long Tube Headers?

    i guess we will all have our own understanding/theories of operation, which is fine. i'm not understanding what the nascar comments are suppose to mean though. in any event, please click on the following link with caution. http://www.ebay.com/bhp/nascar-headers
  7. Long Tube Headers?

    i think its the opposite with regards to length. this is simply because a longer primary tube length helps to isolate the neighboring cylinders from the pressure wave induced in a neighboring cylinder. for example a cylinder is just at the end of it's exhaust cycle and it approaches the overlap period (cylinder pressure should be almost nothing). there will have been a cylinder prior to this that just cracked open it's exhaust valve and induced a high pressure pulse into the exhaust system. the cylinder during overlap will be very sensitive to any pressure in the exhaust. the longer tube helps isolate the cylinder better. header primary lengths generally reduce in length as the rpm requirement increases because of the resistance of the pipe/unit length. tri-y's help with space constraints compared to having all tubes merge at one point but can still act the same by taking advantage of keeping the increased separation by merging cylinders that aren't consecutive. the book "Scientific Design of Exhaust & Intake Systems" is a nice easy read.
  8. is this for the high back bucket? if so, i think i took detailed pics of where are the wires went.
  9. Long Tube Headers?

    you can't use that type of temperature sensor on "shiny" metal. it will read much lower than reality. they are getting false low readings on those coated headers. i'm not saying there isn't an improvement, just not what they are claiming.
  10. Long Tube Headers?

    i don't believe headers need to be equal length. by not being equal length, it simply means the reflected waves will happen at different times. that means each cylinder sees the benefit at different RPMs (and also the bad at different RPMs). as an example, the power generated in cylinder 6 may get a positive bump at 2200 and 4400 rpm, while cylinder 7 gets the positive bump at 2300 and 4600 rpm. with equal lengths and equal cylinder firings (which isn't possible on a V8 without crossing a cylinder from one bank to the other), there would be bigger peaks (and likewise bigger valley's) over the rpm range. therefore with a fully equal length balanced setup, people could probably advertise higher peak power gains. however if they averaged it over an RPM range and compared to an unequal length, there probably wouldn't be an average difference (this assumes the lengths aren't so different that the peaks occur at much different RPM bands). however, having equal lengths may make "tuning" easier if every cylinder acts the same across the rpm band.
  11. Long Tube Headers?

    where did you get this info or how did you make this measurement? I have ceramic coated headers and i'm measure 350 to 425F at idle (dependent on location to the fan....).
  12. ~ 1969 windshield depth .......

    just as a note for anyone doing this in the future... i used the butyl style. i then also used urethane in the corners and possibly a few more spots (to simply to hold the glass in more permanent position). i was concerned with the butyl allowing the glass to sink with the heat from the sun as it stays soft. the urethane hardens up a lot. one thing i hate with the butyl is the fact that it does stay soft and sticky. so bugs, dirt, etc can get stuck in the butyl
  13. what's the MPG on your 428CJ?

    to me, gas mileage is highly dependent on the environment and the way a person drives (driving style, type of roads, duration, climate) which is probably the reason numbers vary so much on the internet. also, it's hard to say how a lot of people check their mileage too (did they have their car warmed up, jump on the highway, drive for a tank at a good speed, then check? or do they drive short durations, on roads with lots of stop signs with every stop includes a drag launch?). I seem to drive more conservatively when I actively monitor mileage on my truck, it's almost like a game. I believe the 1995 Mustang Cobra R (351W, 5 speed) was rated at 12 to 20 (15 average). So if you were rating your car in the same way as they do on production cars, then it would seem you are doing unbelievably good. In my opinion, if your plugs look good after a normal drive, then likely you are close enough, changes won't make much of a noticeable change in mileage.
  14. A REAL Schematic

    really nice job.
  15. 69 mach 408w build

    thank you. tig is so nice, with the ability to control the amount of material added, fusing, no spatter, etc. i've come to the point where i just avoid using the mig 90% of the time.
