It's from GM stroked.
Balanced and blueprinted.
So it's all stock except for the fuel rail.
GM made 427, 427ci motors carberated
And 200, 454ci fuel injected with the ram jet intake from the 502 ram jet crate motors.
One of the enginees found the tooling way back in one of the warehouse's from the 1969 zl1 motors when they were cleaning shop to move to Canada.
They made improvements to the origional design and produced the limited run of motors.
You could also get the block by itself for around 6k
The 1969 and 70 Zl1 aluminum and L72 iron block both accept both the 427 and 454 crank.
This is not something I want to sell, I'm forced to, so please feel free to make cash offers, no trades.

To the top...
Someone has a older Camaro, Vette or something that's been sitting in the garage waiting for this all aluminum fuel injected big block!
Maybe a friend or family member. Dad's old ride needs an upgrade?
Need to sell.
Thanks
