You can also look at the right front of the block, theres a ledge at the front of the head and hidden under the alternator that should have 2 or 3 letters and a series of numbers stenciled on it. They are the engine code numbers. They will also tell you what the engine was. These pages should help, they show where the casting numbers and id code number is.

http://www.yearone.com/updatedsinglepag ... info3.html
http://www.yearone.com/updatedsinglepag ... info6.html At the bottom of the page you can browse through the chevelle, nova, camaro and impala for your id code.
http://www.nastyz28.com/sbchevy/sblock.php#ecode Look under the camaro engine code stamping numbers for your's just have to browse through the years.

Hope it helps, and yeah that looks like a 010 block to me.

Here's what I've found

Block -
3970010 - 1968=327/1969-1979=350 (Also found 1 site that said 302 in 69 Camaro Z28)
Date code E248 = E for May/ 24 for 24th day / 8 for 19?8 (from this I'm not sure how to tell if it's a 68 block or a 78 block)

Heads -
3932441 - one website said 1969-1970 350, one just said 1967-1979
Date code H138 = August 13, 19?8 (??)

Valves - 1.94/1.50 76cc chambers


As far as the pad on the front under the alt. - I could vaguely see what looked like a vin stamped in it, but it was so slight that I couldn't read it. However, under that was a very clearly stamped TH277. The only thing I can find about that is that the TH prefix was a 1978 305 out of a Firebird. Hmm.

Thoughts? And the real question - How does this affect my cam choice?

Still waiting for a couple of guys on the big board to give me there recommendations about what cam to get. Once I get a few more opinions I guess I'll order one.

I really like the old 350/350 horse cam or equivelant. It's got just the right lope at idle, decent gas mileage and pretty peppy. The TRW # was TP112 if that helps.

I googled the tp112 and got this off a camaro forum. Does this look like what you were thinking?

From 1973 Trw Perf catalog,
TP 112 cam 453/453 valve lift, 302/302 cam lift, 284/284 dur, 55° overlap Hyd.

Also, this was one opinion off the big board. I just don't know enough about it. Getting kind of confused with all the numbers.

If you stick to a "conventional" cam you may want to stay around or below 270 degree "advertised" duration. 214 at .050 would be acceptable.

Not sure what he means by "conventional" but sounds like he may be talking stock. Here is a link http://www.chevyhiperformance.com/techa ... index.html that may help.Here are some definitions that may help also.


Lift is the maximum amount that a cam lobe will open the valve.

Duration is how long the valves will stay open from unseat to seat in degrees of camshaft rotation. Duration begins at .004 inch of camshaft lift, when the lifter begins to ride the ramp to peak lift, coming off of the base circle.

Duration at 50 means duration, beginning at .050 inch of lift at the cam lobe. This is the industry standard for duration on each cam lobe.

Lobe Separation or Centerline is the amount of time between intake and exhaust valve action. This is in degrees, typically between 102 and 114. For street engines, we want lobe separation above 112 degrees for a smooth idle. Anytime lobe separation goes below 108 degrees, idle quality suffers.

Overlap is the period where the exhaust valve is still open, yet closing, and the intake valve is opening for intake stroke. Overlap allows incoming air/fuel to push spent exhaust gasses out. This contributes greatly to the power picture. Valve overlap allows for good cylinder scavenging between power cycles.

The Ramp is the ascending or descending part of the cam lobe that leads to either the base circle or the peak.

Flank is the ascending or descending portion of the cam lobe past the base circle nearest the area of peak lift.

The Base Circle is the base portion of the camshaft where no lift takes place.
The Heel is the bottom of the cam lobe where there is no lift.

Intake Centerline is the position of the camshaft as it relates to valve-timing events. If the intake centerline is 114 degrees, for example, the intake valve reaches maximum lift at 114 degrees of camshaft rotation.

Exhaust Centerline means exactly the same thing as intake centerline, with the exhaust valve reaching maximum lift at a given number of degrees of camshaft rotation.

Adjustable Valve Timing is when we have an adjustable camshaft sprocket that allows us to advance or retard valve timing to increase or decrease torque. The objective is to make the most torque possible. Advance valve timing, and you increase torque; retard valve timing, and you decrease torque.

Dual-Pattern Camshafts employ two valve-timing patterns, one for the intake side and one for the exhaust side.

pull iT apart and you will know what it is. Whatever you do, Do Not DE stroke A engine For a truck!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Do not Destroke any engine unless you have some rule or requirement to run a bunch of rpm and have no other way to keep it togather. A well built mostly stock 350 with a really mild cam will pull the paint off an equaly built 327 302 in the same weight vehicle. its phisics. You don;t grab a short wrench to pull out a tight bolt. Trucks are heavy. if you like spinning one to the moon and have the money get some 4.56 gears and build a 302 with some ford 300 6 cyl rods 12 to 1 on pump gas woot.
