I clamp vise grips on the tubing wrench to help keep it from spreading apart. Often helps on a tough fitting.

Ignition is stock distributor and coil, plugs are 44 Autolite, 36 total advance. Compression is 11.1, the combustion chambers are a little big, came that way from factory, and I wanted to run a composite head gasket, so I had J&E make pistons to my specs.

Rebuilt my 69 Z engine this past year. Been in the car for 35 years and I decided to go through it. Only variations from stock specs are .040 overbore, 3927140 off road camshaft, stiffer valve springs, 69 GM crossram, and 1 5/8"primary 3" collector equal length headers. Best numbers were 370 lbs. torque @5700 and 417 H.P. @ 6700.

Right in that 1976 timeframe I went to look at a Z-28, engine out up side down on the carport floor with a bad crank. Car was silver, black stripes, radio delete with 30,000 miles showing. Had a few scuffs wasn't a garage queen, passed on it at $1400.00. Like to have that opportunity again.

I stripped a JL-8 car in 1976. Car had had a very rough life totaled and rebuilt, then wrecked several more times. My brother and I bought the car for $1800 (borrowed the money from our Dad). I thought I would put the rear-end in my Z and sell the car, then I realized the whole front set was different. So I pulled the cars nose to nose and took everything down to the master cylinder. I took the brakes, my brother swapped the trans, heads and intake for junk stuff and we drove the car to Seattle and sold it to a dealer for $1800! Still running the brakes, long story, but shows how different times were.

Jon were there any modifications allowed, head porting, compression, etc? I've read that top teams made power in the 450 range, good #'s for stock stuff.

I was thinking higher on the low side with a four speed they would have wanted to keep up in the power range. Just a guess haven't ever done that type of racing.

May have been discussed already searched around and couldn't find anything. What RPM range did the cross ram equipped Camaros see on the typical track. Just curious. Thanks

Points float seemed to be an issue back then. Don't know if good HD point sets weren't available, or we didn't know where they were. In any case a Mallory dual point was the speed tip of the week. When I purchased my current 69Z in 1975 the deal was done and I thought to ask if he had any extra parts that he had removed. Walked away with the original carb and distributer which were on a shelf in the garage. Lucky catch

Maintenance / AC R44SX
« on: September 21, 2018, 09:11:25 PM »
I've used R44S in my 69 for years I'm having a hard time getting them. Anyone have any info on the R44SX part #5613591? I have ran across some but can't find info on difference from R44S.

Out of curiosity I checked out my 10/76 parts manual, appears there's a JM code listed for 1969 Chevy II. Typo?

Originality / Re: 69 Oil Pressure Line Firewall Hole Location
« on: April 18, 2018, 02:44:41 PM »
It appears these holes jumped around a bit. Differing maybe by plant, worker, and production date. Surprised the AIM doesn't give specific measurements, too far one way or the other could run into stuff inside!

Red, was your car assembled at NOR or LOS? The firewall oil line penetration on my LOS car is not in the location shown in the AIM, and I've determined that several other LOS cars have it in the same position as mine. NOR assembly seems to have followed the AIM locations.
My car is 12C LOS

Went through the AIM, and searched topics on forum. Not too sure which location 1/2 hole should be drilled. I assume it's drilled in the lower dimple shown in attached photo?
