Default Engine questions...help please :0)

found an engine just freshly complete rebuilt and balanced. the pistons are TRW .030 with a new 327 vette 350 horse power camashaft. the engine was done to the stocks factory specs, the timing chain is a new double roller chain, all new bearings,brass freeze plugs,oil pump etc. the heads are all redone also, now the the casting numbers and dates.

1)the intake 3919803 date of L 26 7.

2)the block casting 3914678 date of A 11 8. on the ft pad vin is 18N380382 VOII5EE.

3)the heads casting is 3917291 date of L20 7.

I have a late 1968 which originally had a 327/350 SB. Can someone help me with de-coding the info above? would this be a good number match for my car? My car was #200 from the end of the 68 model year.

Thank you!

Your block originally came out of a 68 Camaro assembled at the Norwood, OH plant. The block was cast on January 11th, 1968 so it's a little too early for your car.

Also note that the engine is a L30/M35 (327/275 with a Powerglide automatic transmission), and was assembled at the Flint, MI plant on January 15th, 1968.

Depending on a persons definition of 'numbers matching' the answer could be yes, no or maybe. The casting numbers are correct, but the dates are way off- all too early. The stamp pad pinpoints this engine to have come from a different type of car with a different engine option.

Most people at one time intended 'numbers matching' to infer it being the original engine installed by the factory. Seems now there's dozens of definitions.

that is just another small block with 44 year old primary parts. the dates are way off and the stamping is wrong. you will not be increasing the value of your car by buying that combo so do not pay more for the engine unless that engine combo's asking price is close to any other freshly rebuilt small block. also consider who you are buying from. is the price close to any other price you could buy a SB crate engine for? does it have a guarantee? how would you make a claim if it is guaranteed? will it cost you hundreds to ship? will it cost you hundreds again to ship there and back if you have a problem?

a crate engine with its guarantee is the way to go unless you are wanting to build a numbers correct combo which will give you a increment to the value of your car.

a properly rebuilt and stamped and date coded 327 will probably cost you 4000$ and you might get 5000$ more for the car... ain't worth it...

By the way, HERE'S the engine. It's been on ebay 16 times since February of 2011 without selling, so that should give you an idea that's he's probably asking a little too much for it.

You're joking Mike, but yes, there actually was a cam exclusive to the first generation Camaro! The Z28 302/290 cam.

I can't see any value in buying that engine for your car. What would it achieve? Bugger all in power and it will never be a number matching combination. If you had a friend giving it to you and you needed a donk to but in - then yes.

thanks for all the feedback guys!

yes, i agree with you all. i really need a "correct" engine for my car. a late MY '68 327/350 engine in good running condition. i've gotten a few calls on the engine in it now, and a couple of comments that the engine i have is on the rare side for a '69 vette...thoughts/comments on price/condition? THANKS!!!

engine info currently in my car:

Engine block # 25GM 3970010 4-bolt main (1969) 350 having +360ci with about 11.5:1CR

Pistons TRW# GM633/634 L2304 060

Heads # 3782461, 327 double-hump heads 161/62cc port (1968)

Engine runs strong. Slight "ticking" sound of valves/lifters can be heard at idle.

You need to do what works for you, but the car will never be "numbers matching," so if you are thinking in terms of value I would think you'd come out ahead dropping in a "period correct" small block, 350 or 383 that's been built with quality parts, dressed up nice and makes some torque. Keep a notebook with before, during and after pictures, along with receipts and part numbers from the build, and cap it all off with a dyno sheet. I have a buddy who did something similar with a Mustang, and people love the notebook--they spend twice as much time looking at the book as they do the car.

This is just my 2c, but if I was looking at a car I'd be a great deal more impressed with that than I would with a 327 with the right build date.

Good luck!
