Hey guys. So I bought a 1947 *****'s wagon that had a small block Chevy. The motor came out of a 1958 Corvette. It's a 283 with a stock powerglide. I am pretty sure all of the components of the motor and tranny are stock. So I am wondering if there is a value to the motor or leave it in my *****'s. Thanks

Tell us what is stamped on, or better yet post a picture, of the engine front pad.

So I hope this helps. Check out the pictures. Let know if there is any other numbers I need to get for you. Got the heads rebuilt so far. Thank you

772 heads are 58 2 barrel pass car, PG has a 59 casting date and stamp pad E code is not Corvette.

Ok thank you for the information

Stamp pad looks altered as well. Not a Corvette engine or parts. It seems that 99% of all small block Chevrolet's transplanted in other vehicles are 'Corvette engines'. In 40 years, I've think I've seen a real Corvette engine in a donor vehicle maybe twice. Out of about 800 vehicles.

The "E" designation actually fits a passenger car Turboglide, 1959-61 283 cid. Remember those trannys? The shift selector had GR (grade) instead of L (low). The TG was a piece of junk. It had a five element torque converter instead of three. It was the first aluminum case automatic produced by Chevrolet (perhaps GM, too). The cases were known to crack under high pressure. They worked better (not much) with the SB; in the 348, they were much more prone to failure.

I actually think the engine pad is original, and is stamped FII4E, but that engine pad was improperly cleaned (like with sand paper) that was scrubbed against the grain of the block.

The casting date on the block looks like L 13 7, or L 18 7, or L 19 7, so Dec 13-18-19, 1957.

Now here is an interesting question. Forget about the block casting date and just look at the engine pad stamp

F = Flint
II - 11 (November)
4 = 4th
E = 2bbl, turboglide in a passengers car

OR

F = Flint
I = January
I4 = 14th
E = 2bbl, turboglide in a passengers car

This is one of those "odd ball" engine stamps that could be interpreted in more than one way.

Stamps (from 1957 to mid January 1960) that has an assembly date starting with "I0", "II" or "I2" could be January, or October, or November, or December. "I3" or greater obviously doesn't work, since there are not 13 months, so "I3" would have to be either "I30" or "I31" (January 30th or January 31st).

This confusion was resolved between Jan 15 and Jan 18, 1960, when a leading zero was added to the month indicator. The leading zero was already part of the day indicator.

For engine stamps that fall into this situation, the casting date is also needed to determine the correct engine assembly date.

So, for this engine, with a casting date in the middle of December, 1957, an engine assembly date if Jan 14 makes more sense than an engine assembly date of Nov 4

November 4 would likely be II04, not II4.

Good point, and nice catch.

I completely forgot that the day would have a leading zero.

Disregard my previous ramblings.
