Default Re: 11D COPO Chevelle???

The discussion about this car is getting more interesting all the time. I have been reading about it on the Chevelle site. It seems that whatever his name is has been planning this for several months. Here are some of his post from as far back as December 2003.

I would like to know how common it is to restamp and engine to make appear Nos matching and how can you tell if it has been restamped?

Hey guys here's one I found a complete 427 in engine very good running condition wiht the following info:

Casting numbers: 3963512

Motor No: T0324MP

By the oil filter Hiper F Pass

The pad number though looks to have been restamped possibly defenitly decked.

It seems to be less compression and was rebuilt to a lower performance HP.

ny comments on the authenticity of these codes. I was think about finding a 69 chevelle that is an SS 396 with matching No's througout and popping this bad boy in it built back to yenko specs or at least to the the near same 425 HP rating?

Well I do see your (nice Ones) are going for, and they are just using a regular non date matching 427, 454 block or 396 blocks with 427 cranks and acessories, not the real deal.

How about a car that had the matching No's engine long gone, but the rest of the gear still original, then ;pop in this engine of the era with the right s=date number anyway.

As far as casting number go can those be faked?

Ok guys here's one for your noodles here are some codes tell me what you think:

VIN 136379B326463

ST69 13637 BAL161444 BDY

TR 795 65 EPNT

11D B L 074899


Bell Housing Cast No. 3963512 B11 70

Intake# 3933163

Head # 3919840

Oil Filter area cast
HI PERF PASS

Head # 3919840

Sopposedly the head pad number behind the alternator matches the last No. on the VIN.

My thought was this is at the very least is a COPO 427 Engine from 1970 probably a replacement for a blown engine. I was think that at the very least you could call this a very original COPO replica.

Ideas on value or if it is a COPO car?

Yea hey von thanks for that I did look all tyhe numbers, I can get the car probably for 10000, the guy is desparte, but he already sent all the numbers to COPO allegedly and they said no or some place thatt gets money if they can confirm it's status.

But yea it's feasable that it's COPO ordered engine, but I was thinking someone did a good job
putting the engine together to look like a COPO, but hey isn't a good replica worth it if it's in good shape?

OK here is the deal, I have a 1969 Chevelle I just bought VERY STRAIGHT No Rust, was restoreda while back, here si the conflict I am facing:

It has a COPO 427 with the proper heads and intake solid cam and lifters, but the car is a late 1969 Mid November adccording to the Cowl tag, and the engine althoug is casted properly for the COPO it is also date coded on the bell Hosuing B 11 70 February 11 1970.

No one can tell me if it's a real COPO, if it was it would have had to have been ordered in late 1969 with a wait on the engine, which I don't think is too inconceivable. If it's not a COPO chevelle in the restoration should I make it a COPO chevelle replica or Yenko Replica to achieve it's best market value?
