Originality / Re: Muncie Shifter Assembly
« on: January 02, 2017, 04:27:09 PM »
I think you mean Muncie and Saginaw not Muncie and T10 ?

I looked at some I have for Camaro and Chevelle and the shifter stabilizer bars look to have been black but I would not be surprised if they were black gray or silver. I don't know if GM held the plating requirement so tight that they didn't allow a wide tolerance.

I know with 69 rods have seen the forward rods silver and the Rev rod black on same set of rods

General Discussion / Re: Cowl Plenum VS. Cowl Induction Air Cleaner Systems
« on: December 28, 2016, 05:02:01 AM »
Cowl Plenum and Cowl Induction Air Cleaner Systems use the high pressure area at the windshield to provide a very small "supercharger" effect but more then that is the effect of air temperature.
Cooler intake air makes more power.
Chevy used cool air intake systems on many cars and trucks in the 1980s with the Q-jet 4BB and other induction systems. It was just an air hose from the grill to the air cleaner but it works.

here is some info found online I thought was pretty good.........


Air scoops of various kinds are a common feature on cars with performance pretensions. Many scoops are purely cosmetic, but those that aren’t typically serve one or more of the following functions:

COLD AIR INTAKE

Burning fuel requires oxygen. Unless an engine carries its own oxygen supply (as with a rocket engine), that oxygen must come from the surrounding air. The amount of oxygen available to burn — and thus the engine’s maximum power output — depends on ambient temperature and local static atmospheric pressure. As a rule, cooler, denser air will yield more power while warmer, thinner air (such as on a hot day or at high altitudes) yields less.

The engine compartment of the average automobile tends to be very warm indeed. The normal operating temperature of the typical water-cooled passenger car engine is well above 160 degrees Fahrenheit (71°C) and an air-cooled engine may be considerably hotter. The heat radiated by a running engine quickly heats the air around it. Since most automotive engine compartments are enclosed and rather cramped, with few opportunities for the heat to escape, the air in the engine compartment is usually significantly hotter than the outside air. If the engine draws its intake air from under the hood, the high temperatures will reduce the density of the intake charge and thus reduce the engine’s net power output.

An obvious solution to this problem is to add a cold air intake channel that allows the engine to draw its intake air from the cooler, denser air outside the engine compartment. An effective cold air system can counteract much of the power loss caused by high under-hood temperatures, potentially improving engine output by 5% or more.

Simply cutting a hole in the hood does not a functional cold air scoop make. To be effective, a cold air intake (a) must be located in a high-pressure area of the hood; (b) must be designed in such a way that it actually allows outside air to pass through the inlet; and (c) must have a tightly sealed connection to the air cleaner and intake manifold so that the engine will breathe through the scoop rather than drawing some of its air from under the hood. The distance from the scoop to the air cleaner must also be as short as possible — the greater the distance the incoming air has to travel, the hotter it will get, both through friction and through absorbing engine compartment heat. A poorly designed or badly placed cold air scoop can be worse than useless, costing power by restricting the flow of engine air.

General Discussion / Re: Yenko sold Z28s
« on: December 17, 2016, 04:59:27 PM »
some of this has been posted before but if any new people are interested

Don Yenko was known for selling 427 Camaros and racing Corvettes but he also raced 302 1st gen Camaros

Don had a 67 home built Z/28 which he ran with Jerry Thompson

Don had one of the old Smokey Yunick 68 Camaros he ran some Trans Am races in 1969 and won the Daytona Citrus 250 with it. This car had some sheet metal covers on the head lights that sort of looked like an RS grill

Don ran a red 1969 #5 Camaro in partnership with others and this car can be seen in the Movie "The Racing Scene" 1969 James Garner movie

Don ran a blue and white #9 1969 Camaro in 1970 with a 302 in some races and ran it with a 427 ZL1 engine at Sebring 1970.
It was said to be very fast and ran with the 427 Corvettes but broke

thanks to Jon for some of this info

thanks Tim

I was always curious about the Yenko Sportscar Dealers sponsored drag car that looks like it may have been a 67 Z/28

it was run by Tony Pizzi who had a shop in PA.

I met a guy who knew Tony (Tony had passed away). He didn't know much about his 67 Camaro but knew Tony's 1968 Camaro drag car which he said was built to Z/28 spec by Tony.

The 67 looks like it may have been a real Z but its hard to tell as many race cars were home built and I don't know if it was bought from Yenko Chev

I think the Yenko sponsored Pizzi car may have only been run for a short time in 1967 because Yenko took over the 67 Camaro drag racing program from Nickey Chevy.
Together with Dick Harrell, Yenko got the 427 Camaros legal for AHRA and Yenko sponsored the Harrell 427 Super Stock Camaro and 67 Camaro Funny car.

does that list include the early Z/28s that were used for racing?

« on: December 06, 2016, 10:00:30 PM »
how long is the chrome stick?

early Chevelle or Impala was 12 or 13 in
when you get to 14 15 , more likely a truck shifter

looks like a pick up truck 3 speed

Research Topics & Reports / Re: Hurst Shifter date codes
« on: December 06, 2016, 09:52:23 PM »
something I noticed over the years working on Hurst shifters

they changed from sliver cadmium plate to black phosphate about 1970 from what I can tell

the aftermarket shifters also changed from sliver cadmium plate to black phosphate

I think HURST worked in the change over a period of time because they had so many different shifters

that's a great video

also has an interview with Dale Armstrong and his Canuck FX Chevy II

not long after that, Harrell went to work with Yenko Chev and Armstrong with Dana Chev  to run 1st gen Camaros

I like dusk blue , its got the 350 , many of the driver Camaros I have seen like that had the 307

Trans-Am Camaros / Re: 50th anniversary of the first Z-28

congratulations Jon  Great Job on the car and the history

I'll toss in the M22Z gearset that was not mentioned and designed around a 3.08 rear. 1st gear is 2.984:1. Combined with a 3.08 rear, the take off is like a 4:10. Gear spacing is a little wide for a 4-speed but a cheaper alternative for those who don't want to burp for a 5-speed.

they used to do that with the late 1970s Z/28 and Trans Am wide ratio T-10 4 speeds .
With a high rear gear , it was called the poor man's 5 speed

General Discussion / Re: Repro tach burned out
« on: September 13, 2016, 01:19:53 AM »

The points run on a resistance wire with about 9.7 volts
on cranking its 12v but runs on 9.7v
many aftermarket ignition run on 12v and don't use the factory resistance wire but  factory tach still needs the lower volts

here is a link
