Need some help on a little mystery.
1970 454 LS6 Block casting code: 3963512 Date Code: E 18 70 (May 18th 1970) Engine Numbers: T0616CRV Partial VIN: 18B208611 Head Casting Codes: 3964291 Head Date Code: E 7 70 / E 8 70 (May 7th / 8th 1970) Engine decoder results: Engine assembly plant: T= Tonawanda, New York. Engine was assembled in June, day 16. Engine assembly code "CRV" was used for the following vehicles: 1970 Chevelle 454cid Manual trans 450hp CRV What is wrong with that picture? The VIN has an 8 for the 2nd digit.. ???? Should be a zero for 1970. The VIN sure looks to be 100% original. Explination??? Could the 8 be a mis-stamp from the factory? Thank you for the help

Billy,
Baltimore is a plant known in 70 to have used 3 different variations of v.i.n. stampings. 10BXXXXXX, 18BXXXXXX, and 188XXXXXX are all known real partial vin stamping styles we've documented over the years. Most of the odd stampings seemed to be early in the production run but I've learned a long time ago to never say never. The pic on my monitor is not clear enough for me to comment on originality, but from what it looks like it's possibly OK. Chris |

My concern on this one would be the first "6" in T0616CRV. I haven't seen a Tonowanda stamp with a curved leg in the 6 before.

So the block was cast in Tonawanda and built and stamped with a partial VIN in Baltimore?
Thanks for the education!

Billy,
Cast and assembly dated with I.D. suffix in Tonawanda, v.i.n. stamp is always done at the final car's assembly plant. I have seen the curved 6 before, and given the 2 6's used in this engine's assembly date not unbelievable. I would want a clearer picture of the stamp pad before I'd comment on it's possible originality. Chris |

I have an issue with how close the "V" appears to be next to the head as the head is on the block when they stamp it. I see this quite often. [img]<<GRAEMLIN_URL>>/hmmm.gif[/img]
Unless it's the way the picture is taken. [img]<<GRAEMLIN_URL>>/dunno.gif[/img] Kurt

Kurt,
I don't believe that's correct regarding when Tonawanda stamped the blocks. Pics I have seen show the heads not installed at the time of stamping. I've also seen original motors with the stamping very close to the head. Obviously the vin stamp can't be too close to the head as they definitely are on for that proceedure. Chris |

If someone was trying to fake it, why would they use two different 6s?

I concur with Chris, heads not installed when pad was stamped.

Verne [img]<<GRAEMLIN_URL>>/hmmm.gif[/img] </div></div> Chris has already said that he's seen the 2 different 6's. Works for me. |
