Maintenance / Re: Balancing flywheel and clutch assembly together?
« on: November 25, 2022, 03:43:30 PM »
I'm a bid advocate of it, as I HATE doing things twice. You'd be surprised how far off a pressure plate can be.

Tim

Totally agree, I had a well known brand name pressure plate that was off 23 grams, they all seem to be off a bit but not usually that much. We all ways zero balance the flywheel, then bolt on pressure plate and make any changes just to the pressure plate, that way everything is zero neutral balance.

The picture of the lower flywheel appears to have 4 bigger holes in the back area, which is not stock GM balance IMO. Like mentioned the motor may have been balanced with the flywheel, so you could have a engine shop check the balance on both flywheels to see if they are close, but i doubt it.  I have seen shops do that instead of adding heavy metal to crank counterweights.

The link i previously posted is for the shorter rear bowl screws on 4160 carbs. This link is for the longer 2.5 bowl screws.

Check the rear shifter stop adjustment bolt (which is for 1st & 3rd ) and make sure it is not screwed in too far when in the 1st gear position, ( check in both positions )  and also make sure shift handle and 1-2 rod is not contacting anywhere .

Usually rebuild kits do not include the outer sliders. Weird itís jumping out of 1st because usually the 1-2 slider does not wear much on the 1st gear side. Do you have a stock shifter or a Hurst ? May just be a shifter adjustment

Maintenance / Re: Z28 Cam

You should pull the valve covers and WITHOUT adjusting them run the lash to see what it has rite now for lash. The stock cam is .030/.030, if its anywhere close you can make a decision and relash it at that. You could also use a dial indicator and measure the lobe lift at the pushrod, but you would have to remove 1 rocker, then multiply that by the rocker ratio to give you theoretical lift, Z cam is .485. You could also put the dial indicator on the retainer and that will tell you lift at valve.

Short of putting a degree wheel on it its hard to measure duration.

First picture of the primary metering block has a 65, second picture of secondary block has a 85.
You read the numbers on the right hand side, the left side with the aplha numerical digit with a number underneath it is not a identifying number. You can also tell the higher value power valve by the effort it takes to push the other side of the valve although the difference between 65 & 85 is negligible.

The 6,000 mile 1970 LTI engine I have had for 25 years has black non flanged bolts, "M" head, and the threads are black, 1st time a intake bolt has ever been removed was today. You can see remnants of brushed on aluminum paint on bolt sides. The stand bolts appear natural.
 The lift brkts are natural BTW. Pretty sure my own 69 Z has black bolts to. Hope this helps.

Mike.

I would contact Richard English from Camaro Heaven to see if he has a record of where it went. Here is a picture of it from Edmonton International Speedway , late 70,s.

Is that the car that R English owned at one time? I thought I remember seeing it on display at Motororama in Toronto years ago.
The display sign referred to it as "The Great Pumpkin"

I Donít think it can be the same car that was originally posted .

The Richard English Camaro Heaven Z28 was owned by long time drag racer Ken R, out of Edmonton Ab, it was a race car for many years and went through lots of changes over the years with different motor combinations, but it was a black/orange houndstooth car too.
