Re: Restoring Rusty
well naturally now we needed longer carb studs, so we tried the 2" tall ones and not even they were tall enough
so we hit Oh'Reallys and picked up the 2 1/2" ones and they did the trick |

Re: Restoring Rusty
by then it got too dark to take a final pic, but we got everything assembled and after tightening that silly hex stud in the chrome dual hard line inlet we stopped the gushing gasoline fountain
we squirted some gasoline into the float bowls via their vent towers and the truck fired right up I adjusted the float bowls so that the gas is half way full in the sight glasses both front and rear float bowls the truck warmed up in the garage and then we took it around the block for a test drive, it ran good I kept the same carb configuration I had before: 69 primary jets / 73 secondary jets (I think best I could see) 35 accelerator pump squirter 10.5 power valve (cause I'm pulling silly strong 20 inch vacuum at idle) yellow vacuum secondary spring no idea what color accelerator pump cam, will check in the morning (what ever stock one it came with) Last edited by Gregski; 03-04-2017 at 01:53 AM. |

Re: Restoring Rusty
Well, there we go. Mystery solved. Apparently adjustments are meant to be made by judicious bending after all. And now I know what the first custom aftermarket part I ought to invent is.

Re: Restoring Rusty
I have had a truck since I was 19. I don't like borrowing a truck. If you own a house you really need a truck. Be it big or small a truck will save you in the long run. I have a small truck. It's plenty for what I need. I get my 76 on the road and I'll have two. Glad to see you back Greg.

Re: Restoring Rusty
Good on fixing the hard line clearance. I had the same problem installing the one for my Summit carb. Funny...a gazillion carbs using basically the same setup on a gazillion SBCs, and it doesn't quite fit.

question for you alls do we need to put some sort of gasket, oring, washer inside the hard line fittings to mate it to the carb, I put mine metal on metal and I am wondering if it will start leaking, so far so good, but metal don't like to mate with metal really well if you know what I mean? |

Re: Restoring Rusty
so not sure I shared this with you, but last October I tried yet another exhaust though it was short lived (ran it for a week or so) because I had that dreadful crank bearing problem
anywho I took it off thinking the noise was another exhaust header leak, turns out it wasn't, but I was running my exhaust manifolds with stockish turbo mufflers ever since, well until today today we will put the Thrush Rattlers back on, or as I like to call it Exhaust 8.0 Hey what did you expect was going to happen when you leave me un supervised, LOL |

Re: Restoring Rusty
these are single chamber and they are not a pass through design, in other words you can't see through them, not the best for horse power and flow, but hey according to their website they are "Making Hot Rods Hotter"

Re: Restoring Rusty
and so I got to build them, here they are being compared to what I had prior, a very loud straight pipe with only 9" resonators, did I say it was loud
these will have a more turn out style tip, dumping the dirty exhaust in front of the rear tires and right into the Prius stopped at the light next to us, two if we happen to be in the middle lane, win / win Last edited by Gregski; 03-11-2017 at 10:39 AM. |

Re: Restoring Rusty
tired of welding the resonators backwards in my last exhaust I decided to label the flow of the new Rattlers with some blue tape, so I weld them up right, as I believe unlike the Magmaflows these be directional
nothing to it but to do it |

Re: Restoring Rusty
so got the Thrush mufflers welded to the front pipes and then welded on the tail pipes, again I like to run my exhausts just to the rear axle so I don't have to do the surpentine looptie loop around it, that may be part of my drone proplems but hey that's how all the cool kids run their exhausts, hee hee

Re: Restoring Rusty
a little mini update, so went back to the Remflex gaskets specifically designed for the L31 Vortec heads to ensure there are no exhaust leaks, also treated myself to some ARP header bolts, mostly for the much smaller bolt heads, should make turning them a bit easier in the very confined spaces that the headers provide
here's a little Top Tip on building your own DIY exhaust: if you design it with the parking brake on, ie the cable tension tight, when you release the parking brake for driving the truck, it might could hit the exhaust pipes, and ding like crazy, just sayin' |

Re: Restoring Rusty
so the truck is pretty dialed in, the new exhaust is not quite what I was looking for (a nice deep rumble) but it's the best sounding so far, (louder than the Magnaflows, yet no drone like the Flowmasters) I may keep it for a couple [ahem] days, hee hee
here's a near perfect idle AFR (Air Fuel Ratio), I hope to get it Dyno Tuned by the end of this month, here's hoping... life has been beating up on us pretty good lately, wife had foot surgery and is to recover with a big cast for 6 weeks, so we are a (wo)man down. |

Re: Restoring Rusty
I always use an "H-pipe" when building exhaust. Flows better, less drone, nice rumble - but quieter. Summit has them in their brand and they are aluminized too, pretty inexpensive !

Re: Restoring Rusty
thanks, I have tried the X pipe before and dreaded it, PIA to install and get all the clearance, plus I like a true separation in a dual exhaust system it allows me to quickly see which side of the engine is doing what and narrow things at least to one side, and part of me things the H pipe is a sham, lol
