the 429 was in the car when i bought it,its cool to have a bb but its tired, its very heavy, its not a high performance 429, its probably out of a truck or station wagon. it was not installed very cleanly, in fact it was shoehorned in. it ran hot and i believe had a head problem. i was gonna put a smallblock ford in it, but the chevy is soooo much cheaper, and im on a budget with this car, anyway, its gone now, we got the new motor and trans in today. got more mods and fabing to do and hope to be able to start it up late next week. ordered headers today.
