Hey guys 

I came across a 1971 Vette that the owner said it is a genuine 454 LS5 with M\T

It does have the right emblems and stickers but I can't find any stamps or casting to verify it.

It doesn't have a Rochester carb, but some kind of holly performance, It has a rear anti rollbar, but it looked like an add on. 

I have some pictures from the engine bay that may be helpful .

VIN 194371S100342

Thanks for your help 🙏

What about the paper emissions sticker that is above the brake booster.  Should have a 2 or 3 letter code for the engine.

That's the sticker!
