66 427 Pad Stamp Restamp?

**Rixls6** · #1 02-07-2010, 12:07 AM

I have a block here that is an LS4 Impala block that has the same type of grind down and restamp, with what looks to be correct Tonawanda characters.
I mean who would restamp a block and make it an Impala 345 horse motor?
I've seen others also that I believe are factory restamps.

Far as the 1P stamping, who knows, but like Charley says, check with the Vette guys.

Thanks guys. Yeah, the 1P thing is also a bit strange. It really doesn't matter anyway since the block will likely be decked when built anyway. I just thought it was interesting.

Thanks for the input,

Jason

1 was very commonly used as an I, and an I for a 1 as well. I have seen many original engine pads that were done this way.

Al Grening is the one who Corvette guys look to for authentication. His data base is incredible.

Don't forget there's cases were pads were sometimes gang stamped stamped including just the first suffix digit as in the 'I' then the 'P' or 'R' or whatever was added individually later when the engine was completed to suit the specific applications..

About 6 years ago here in Tustin,a guy was selling his uncles 1968 Camaro Blue/Blue 210hp 16,000 mile orig. paint 4sp car. The engine code was sanded out and restamped too. I was the first person to see the car and was the person that cleaned off the engine pad for the 1st time. The owners had no idea of engine numbers.

Dont forget all of the Z16 engines had the last letter of the code hand stamped X
This looks like a 65 built engine if I'm reading the casting !

Yes, it is a late 65 block.

Thanks guys!
