So i got around to getting some numbers..
So far we know that it was built 5-16-69, X11, V8 car, Ext Paint is Glacier Blue With Parchment vinyl top, Interior is Ivory/Black, Car has PDB, PS, AC,
I have looked for marking to see if its a real SS and have yet to find any, So we are under the assumption it was a 307 with a power glide,....
With that said these numbers are off the current motor in the car which has no vin numbers.
Front of the block, BLANK V 1204 TBC ( thats all it says) From what ive searched thats a 1970 truck block.
Back of the block, 25 GM 3970010, Those number on here make it a 69-70 block but can be in any car.
above that there is a dial, It pointing to D ( about 1 o clock) below that is circle with dots, at "12" oclock there is a dot above it, the arrow is pointing to 4th hump...
On to heads.. 3947041, L30 3
thats as far as ive gotten, although i have found all the vin numbers on the body and they are same, Not that it matter with the rust lol...

BLANK V 1204 TBC = My literature points to a 1970 4bbl. 350 c.u. used in 1/2 to 1 ton .This is a Flint Dec 4th build. Look for casting date KERR and report back. My experience tells me this is a 4 bolt main block and a good cheap candidate for a powerful street /strip build.
3947041, L30 3 I would double check the casting date and guess it might be an *8* instead of * 3* These are or were great heads in the day. 64cc "camel hump" without the hump used on L48 300hp 350s and 302 Z engine. With todays gas and heads, there are much better, but without spending a lot, these can give outstanding performance particularly if you bore .030
the old adage,"when in doubt,bore it out" works well on a 350 and unshrouds valves.

no doubt, I had a set of those on the corvette, until a nut took a tour of the inisde of the motor, the forged piston are stronger than the head, so the nut punched a big hole in the head :(...
I have no clue what is done to this motor, the carb is JUNK, it can be fixed, but a brand new one is $100 more.. I might just get that Fast FI set up for it.
To me at this point the motor isnt a big deal, It would be cool if it was at least, " something close, a could be" but in the case, the motor cant be built after the car ;) I think im going to just restore this car and put it away.. then find one that cheap to start with.. A one time there was a place on line, I want to say it was in callie, that all they did was sale gm motors, I cant find it now, but they where on e bay, you could search by date code etc...
