1966 vin# 134806b157317
2nd number also listed on regitration sticker is 57745jb, this car has a 400 small block(obviously not origanal) i would like to find what engine it came with. everything is origanal except the paint job and the engine. thanks!

Okay, I'm not 100% sure what you are talking about. Are you asking if your engine is original? If you are, based on the numbers you gave, the answer is no.

He is right...that is one screwed-up number you just submitted..........

Try looking at the front of the motor on the passenger side just about where the cylinder head meets the block...there is a small edge/lip/whatever in that area that should have a large stamped series of numbers(staring right up at you), and a smaller series of numbers under it which should match the last digits of the vin...sometimes there is alot of dirt, grease, or paints that make it difficult to actually see the smaller set of numbers without scraping the ledge down to bare metal......

We are talking about a chevy V8 aren't we????

Some target motors had some screwed up digits though

If ya still can't figure it, take it by a good corvette guy, that is one of the first things we look for when trying to figure a vehicles value.................matchin #'s

I have no clue what the second number on your registration is. You may call the DMV since they are the ones that print the registration information.

As for your VIN, it tells us that your car is an El Camino (standard as opposd to custom), V8 - There were 5897 El Camino (standard "base model") built in 1966. The base engine for this model would have been a 195hp 283cu small block. I'm not sure if you could have gotten the 327cu engine on a base model or if you had to have the custom.

Mid 60's VIN's told you V8 or 6, but not displacement. This is why number's matching is important for mid-60's cars. You can't tell if a car was a base or hi-po model. When you can match the VIN to the block, you know it's the right motor/model. Sometimes this is the only way to prove a car it what it's advertised to be.

On later cars, the VIN tells the exact original motor and model, so number matching is less important. But some people get hung up on "numbers matching" anyway and think it adds tremendous value to a car.
