I picked up a fresh rebuilt 402 from a buddy that got it from another guy that ended up not using it.
My buddy picked it up directly from the machine shop when the motor was complete.
I don't have any info on the motor because the buildup was around 7 years ago and the paperwork was lost.
My buddy told me he thought it was a 1970 402 built to factory specs.
I have all info I could find on the motor and was wondering if someone here may be able to help.
The block is - 3999280
Passenger head - GM4T 3964290
Drivers Head - GM3T 3964290
Intake - 3955287


Any help would be great.
Thanks, Ken
