69 BB car ???

I am trying to muddle through what car I have.

I know its not an orginal engine. The block is a 3963518 MG which tells me the block is a 430 horse (CE). It has a 390 intake on it. Holly 850 with tranistor ignition.

The car has a 6000 redline, a fuel return line and a faded hood sticker (white infront of driver windshield) that reflect a 390 or 400 horse a/c car. All conflict.

Can someone once again share what I need to look for to see if its an orginal BB?

Also, the 3963518 MG sounds farily rare. Any comments on that observation?

Always something.

Check to see if there is a factory rear stabilyzer bar. I think they were standard on the BB cars

In The Corvette Black Book, it says an MG suffix is for a ZL-1 block, which is aluminum, though the casting number is wrong.

Are you sure you're reading the casting number correctly? There is a 454 block with a casting number of 3963512.

Something here doesn't compute. Maybe someone else has better information that can identify it for you.

A fuel pump return line would reflect a hydraulic cam car and concurrent with both AC and the 6K red line. Evidence of the existance a 390 HP 427.

Please correct me if I'm wrong but did the 390hp not have a 5600rpm redline?
I was also under the understanding a 5600rpm redline with no return line would indicate the 400hp 3x2 car?

Big fat straps on the u-joints for BB's.

You're right, the 390hp had a 5600 redline. Don't know the others.
