If you go to the Tire Rack site (www.tirerack.com), they have a tire marking/sidewall decoding page.

The bellhousing was on the engine when it was painted, and normally shows at least overspray on the forward 3"-4", although coverage varied greatly.

Why would you want "original" tires? They're only safe for rolling on and off a trailer. Roll Eyes

It's out of a late Vega or Monza.

That block was cast at Tonawanda on November 9, 1961, so it's out of a '62 passenger car, Chevelle, or truck. You don't have to pull the heads to see the stampings on the block deck - it's right in front of the passenger side cylinder head, out in the open. If the heads are the same vintage as the block, they'll have either 1.72" or 1.94" valves, and the head casting numbers and dates are visible if you pull the valve covers.

GM didn't manufacture their clutches - they bought them from an outside supplier.

That block was only used from '62-'65; if you post the numbers/codes in #2 and #3 above, we can tell you exactly what it is and what it was installed in originally.

Home restorations are done for the love of the car, not because it's a profit-making opportunity; the only people who make money on restorations are commercial shops that do it for a living and bill the customer on a time & material basis, or dealers that fake them and take unknowing buyers for a ride on eBay.
3775  Camaro Research Group Discussion / Decoding/Numbers / Re: 1969 z/28 clutch pressure plate on: June 18, 2006, 07:00:10 PM
Chances are slim to none that it still has the original GM clutch in it, and the aftermarket clutch manufacturers all have their own methods of marking pressure plates and discs.
3776  Camaro Research Group Discussion / Decoding/Numbers / Re: Date codes on horns?? on: June 18, 2006, 06:57:55 PM
The format is YMW (year-month-week); 7C2 would be 1967, March, 2nd week. The date code is on the bottom side, adjacent to one corner of the trumpet opening.
3777  Camaro Research Group Discussion / General Discussion / Re: Anyone know what a factory 427 goes for nowadays? on: June 18, 2006, 06:50:35 PM
There were several at Bloomington this week that illustrate the range - a complete but used 2-bolt '66 427/390 lo-perf short block (no heads) for $5,500.00, and a freshly rebuilt 4-bolt '66 427/425 hi-perf short block (no heads) for $15,900.00. Most fit somewhere in that range, depending on many variables.

Three things are needed to positively ID the engine:

1. The raised casting number (that's the 3789817 you posted).

2. The raised casting date code (about six inches to the passenger side of the distributor hole).

3. Everything that's stamped on the machined surface of the block directly in front of the passenger side cylinder head.

Coker now makes the Firestone Sport Car 200 in E70-15 too - $211.00 each.

3780  Camaro Research Group Discussion / Decoding/Numbers / Re: part #'s for wheel cylinders on: June 16, 2006, 08:47:15 AM
Casting numbers identify a particular raw casting; that raw casting is frequently machined into several slightly different finished parts, which carry unique PART numbers. One example is cylinder heads - the same casting was frequently machined both for 1.94"/1.5" valves and for 2.02"/1.6" valves, and those two variations carried different PART numbers after machining, although both types carry the same cast-in casting number. The P&A parts books show the finished PART number, and sometimes reference an "I.D." number, which is the casting number that appears on the part. PART numbers don't appear on castings, unless a casting was only machined into one finished part.

To carry the analogy further, a machined cylinder head that's bare (no valves, springs, etc.) will carry one PART number, and the same head assembled (with valves, springs, etc.) will carry yet another different PART number, although the machined casting is the same between the two.
