L34 and L35 had two fuel lines, L78 had one.

The hood on the car in the article was an Engineering prototype/pre-production part, made from temporary tooling; an October '68 cover date meant the car was probably driven in June or July '68, before '69 production started.

'67-'68 production schedule was the same as '69; I wrote the CRG Research Report you mentioned. As I said earlier, that engine is OK for your car, assuming the pad stamp date also makes sense for it.

The F0123D is also a 283. Those aren't casting numbers, they're pad stamps; the casting numbers are raised, cast-in numbers behind the driver's side cylinder head on the bellhousing flange area, and the casting date code is on the opposite side.

They'd be the same for either application.
3876  Camaro Research Group Discussion / Decoding/Numbers / Re: 1967 engine block casting date L206 - Dec or Nov? on: February 11, 2006, 02:41:12 PM
"L" in a casting date is December; no reason that casting date wouldn't work for your car. Many Flint engines were machined/assembled within a day or two of the casting date, although a week or two is "typical". If you're taking the cowl tag date as the "build date", that's when the body shell was welded together at Fisher Body, not when the body finally got to Chevrolet and went through final assembly. If your cowl tag says 01A, the body could have been welded together as late as January 13th, and could have gotten its engine as late as January 18th or 19th.

I've got a set of 291 2.02 1.60 heads with matching cast dates. I believe they are F27. is there any way to tell if they were originally 2.02 1.60?

Note the machined relief in the chamber wall adjacent to the outside of the intake valve in the photo below of a 186 head with factory 2.02's; the 291 will look the same way if it had 2.02's from the factory. If it has 2.02 valves and the unshrouding cut isn't present, they were 1.94's from the factory and the shop that installed the 2.02's didn't make the unshrouding cut.
3878  Camaro Research Group Discussion / Decoding/Numbers / Re: block casting and suffix code don't match on: February 10, 2006, 11:57:21 AM
OK here are all the numbers based on info from seller
3970010 casting number, V0105TDB front pad, L228 not sure what this is, H35 509 off back of block 010 776 off back of block
19718606, no clue

dab67

It's a 1979 truck 4-barrel 350/165hp, cast on December 22, 1978 and assembled on January 5th, 1979.

Yes, the front plenum wall had to be cut out; not my car - belongs to Al Maynard.
3880  Camaro Research Group Discussion / Originality / Re: Date codes on 67 wheels? on: February 09, 2006, 03:30:25 PM
'67 wheels were dated, but the dates are stamped on the interior of the rim, under the tire; can't be seen with a tire mounted.
3881  Camaro Research Group Discussion / Originality / Re: 1968 Z28 cowl plenum air cleaner assembly...info...anything on: February 08, 2006, 11:06:15 AM
Here's a '67Z plenum setup.
3882  Camaro Research Group Discussion / Restoration / Re: Package Tray / Trunk Divider on: February 06, 2006, 10:41:28 AM
The divider goes on the passenger compartment side of the reinforcements, with the "hard" side facing the trunk; the divider goes in first, then the package tray.

You can buy a budget-priced aftermarket oil pressure gauge kit and connect it to the hole the production oil pressure sender uses, or if you have a Flint block, there's another oil pressure tap location at the front of the block, just above the timing cover, with a square-head plug in it - it's the same size as the one at the rear of the block next to the distributor (1/8" NPT).
3884  Camaro Research Group Discussion / Restoration / Re: Car Height on: February 05, 2006, 01:27:58 PM
It's taken from the horizontal rocker surface immediately outboard and adjacent to the pinchweld flange.
3885  Camaro Research Group Discussion / Originality / Re: What is the color of the door jamb strikers? on: February 05, 2006, 01:23:58 PM
Wouldn't be unusual to see different latch/striker processes between Norwood and Van Nuys - Norwood was a Fisher Body/Chevrolet plant, and Van Nuys was a GMAD plant; Norwood followed the Fisher Body Operation Description Sheets to the letter, and the GMAD plants did whatever worked best for them and was most efficient, regardless of what the Fisher O.D. sheets specified.
