Just pulled motor from my 67 impala for a massive upgrade and I think I lost a rear cam bearing.
So here it's block # 3999289 2 bolt main. Was re-wrung 10 years ago still standard bore.
Head # 336781 oval port 113.0 cc open chamber screw in stud and guide plate
Motor is out of a late 1973 chevy 1/2 ton Pickup This is a comlete as it gets 1406 Edelbrock Carb and aluminum Weiand Action Plus Intake. Last run 5 years ago
This is one of the most wanted Big Blocks for the fact of it's a High Nickel
Have a couple other big blocks for sale cheaper not this year.
