Looking at 1971 454 LS5 to buy. Just needed some help to verify if everything is possible on match. Trim tag has K07 on it, which I think is June 07 build date .
Vin on pad is T043CPH, C11S117363. If the C 11 is for third month of production is this possible for a June 07 build date on trim pad? Vin pad # match vin on car. It's a convertible with a repaint on it. Not original color but nice looking and asking price is 25,000.

T043CPH is an invalid date and broadcast combo... in the vin derivative th C stands for Chevrolet and your car was 17363 built out of 21801. K07 does = june 07. C11 does = Chevrolet corvette 1971. S = st louis.

your 17363 vin sequence number means your car was built in was built about mid-April 71..

so you have an engine stamp with a invalid date on the broadcast code. a car that was built mid april 71 and a trim tag with a june 07 date of production on it. not something I would pay original engine money for.


25K for a big block convertible is a pretty good price even for a non original motor. you have to decide what your requirements are and if this matters to you. I would pay easily 25k for a big block convertible if the condition was right.

Hi Ted,
WELCOME!
Looking at a 71 CONVERTIBLE!! NICE!!!
I agree with Joe's info. The Trim Tag car assembly date, engine assembly date, and sequence stamp on the engine pad, must all coincide.
Start by taking another look at the assembly stamp on the engine pad to see if there are 4 numbers not just 3 as you posted.
The CPH indicates a 454 engine with 365 hp built to be used in a car with a 4-speed transmission.
We need to have all the info and have it be accurate to tell for sure just what the car is you're looking at.

Alan

Sorry that is T0430CPH

Another mistake. That trim tag showed J18 , 988 for paint and I think 403 for black interior

Hi Ted,
Well, that helps because we now have a May built car which works for the engine assembly stamp of April 30 and the vin sequence of 17363 which works as the car it went in.
NOW!…… there are many other parts that have date codes and part numbers that make them appropriate for a particular car. I don't know if you;'re aware of that if that even matters to you.
One thing you SHOULD check are the stamps on the transmission case which will indicate when it was assembled and what car (sequence number) it was installed in.

Forgot to take jack to get to that , but was able to check a out frame and trailing arms, okay on those. New top, nice chrome and interior. One bad thing though, it was a gray, steel city gray now it's burgundy. He asking 25,000 for car.

Is 25,000 too much to pay for a car that was originally paint gray and is now burgundy. New top ,nice interior and frame in good condition?

If the car has it's original 4 speed to denote whether it's a M20,21, or 22 it'll have a letter at the end of the tranny code-P----Letter. A-M20,B-M21, C-M22. Easiest way to tell Muncie designation. Muncie started doing this after '68. Hope this helps......

Hi Ted,
As much as I know you'd like opinions about it I really can't even offer a guess about the value of the car you're looking at (I'd be doing you a disservice if I did) without having a LOT more information about it, and a series of pictures showing the exterior, interior, engine compartment, and frame/running gear.
For someone who's interested in 'originality' the fact that the car is painted in a color other than the one indicated on the trim tag lowers it's value by the cost to repaint the car in it's original color, BUT, to someone not interested in "originality" the color change may matter not matter a single bit.
What are you looking for in a Corvette? Does the color change matter to you?

Alan
