I gave them the casting numbers for both manifolds when I ordered the kit. It's really really close. The gap is a little more than the thickness of my fingernail.

Charger Discussion / Re: Heater blower
Last post by Nacho-RT74 - December 28, 2025, 08:06:27 AMHere is the route for the blower power for heater function.
At control switch arrives the 14Bk wire power (from Acc) which fill feed either the Heater function (14BR) or the A/C-Vent function (14T) to the speed switch, but not both at the same time.
The brown line will run through all the resistors up to the blower. So will get the more reduced voltage rate of all, so the lower speed posibility, including the A/C Low speed.
With this selection, all other power splices can be despited since will be running practically to nowhere or buckling into the same existant resistor circuit with power already reduced. Except the one for the time relay to the compressor what will be activated anyway straight from control switch (no resistor up to the TDR)
I can explain how the speeds selector setup works on this network if required.

Engine, Transmission, Rearend, & Exhaust / 69 383 manifold/exhaust stack ...
Last post by marshallfry01 - December 27, 2025, 11:09:17 PMJust put new 2.5 inch TTI exhaust on my 69 383 car with factory hp manifolds. Everything fit really good except for the drivers side connection between the manifold and the exhaust stack. It is not quite flush enough. It'll definitely leak as is. I put felpro gaskets on both sides.
Did big block cars come with exhaust donuts at the manifold/exhaust stack connection? Looks like that will be my best option to keep it leak free. Regular flat gaskets won't work unless I'm doing something wrong.

Charger Discussion / Re: Heater blower
Last post by Nacho-RT74 - December 27, 2025, 08:38:45 PMYeap, High bypasses the resistor block. Is spliced into the same line coming from block resistor output (dark green) running to the blower
But for Heater function on A/C cars, they use to be a single speed (dark brown wire line) slower than the low AC speed. No speed selection for heater function. That's on my 74 at least. Hence why I'm asking to the OP about this.
Will need to check further on earliers diagram thought, but on a simple view, the Dark brown signals goes throught All The resistors line up to dark green which is the output to the blower. This is of course if the dark brown wire is hot coming from control switch while no other wire coming from control switch is hot... tipically tan wire which is the default speed for A/C and Vent functions coming from control switch (not from speed selector) and light green wire which is mid speed, coming from blower speed selector, STILL with tan wire to resistor being hot. Speed selector is sourced from same line but the Ohms law makes the mid speed line coming from speed selector a priority over the rest of hot sources.
(I hope sounds clear enough)
