70 LT1 pad

Re: 70 LT1 pad

This looks typical for a few LT1's I've see - as far as having the suffix appear to be stamped separately/deeper in the pad. Here's a reference pic I borrowed from the ProTeam site a while back of another LT1 stamped the same day as the pad in your pic, although the suffix isn't as deep. The stamp placement is almost identical, although the "0"'s are a bit different.

If the factory broach marks are present on the pad, I'd be leaning toward saying the pad in your pic is original, but... let's have the "experts" can weigh-in here...

Re: 70 LT1 pad

Given the "Patina of age" matching the surrounding area, there is a high probability it is good.

John here are 2 photos of a 70 LT-1 we judged and accepted as a factory grind out. Its has many features as your photo has. Plus the build is very close to the car your looking at. Paul 18046

Re: 70 LT1 pad

John, does the owner have any paperwork (bill of sale, build sheet, POP, etc.) to substantiate that the 'vette was "born" as an LT1?

Ken,
Nothing other than old service reciepts which may lead somewhere. I'll look for tank sheet but don't have high hopes for that.

Re: 70 LT1 pad

For those of you who may be interested, I went and looked at this car and can offer the following.
The engine pad does have broach marks, dim but there. What's really interesting is that the engine code and date stamp are nearly identical to the one posted by Paul Olansky which was made ON THE SAME DAY and had both an O and a 0 in the same positions. What are the chances of that being faked?

Re: 70 LT1 pad

John after looking at the stamp pads next to each other. The same holder and stamps were use on both engines. Each photo was taken at a slightly different angle causing a small deviation but the change from number to letters is almost exact. I would say the pad is good. Just my opinion others may see it differently.

John,
Just wondering what you thought of the car, was the tank sticker on it?

I'm kinda new to the N.C.R.S. world, so I ask you & other board members this; Is an LT-1 stamping any differant than a "regular" 350 in a Corvette or any other Chevrolet (being GM correct & not using Chevy

) my 1974 L-48 looks like this, with the appropiate broch marks. I'm not trying to steal your post John, just trying to get some knowledge! Comments?

All engines came down the same assembly lines at the various engine plants. Same guys, same tools, same stamps. The last two or three characters varied according to the build spec of the particular engine.

Re: 70 LT1 pad

Hi Joe,
The car is a very original car. There are some issues with rust in the windshield pillars and the lower birdcage channels, all repairable. Everything works, it runs well and drives nicely. No tank sticker and an odd but correct pad stamping.
Depending on what you would like to do it's a good driver and a good candidate for a total restoration.
For me the latter turned to be too much $$ without any docs.

What do you mean by "factory grind out"?

Do you know if the broach marks can run either in a front to back direction on the block or across the block (left to right) if standing (viewing) from the front of the car.
