I think,.... the 527 is the maximum they can be bored to I know the Shelby has much more meat but, the price is incredible. Also, like with any engine, the more troubles you can encounter with very large bores.
The walls are much thinner.
If you hurt a cylinder, the block is done.
If a rebuild is needed, sleeves are needed.
Increased heat.
Of course, it's more expensive.
ect....
I guess I'll have to sell the shirt off my back, to pay for a Pond or Shelby aluminum block.
I do have many sponsors for this magazine build but, the block is hard to swallow and takes up a lot of my budget.
Anyway, since I'm back from the dark side, with the ALUMINUM block. Talk to me about the parts used and the specifications or your motor.
Is there anything you would change ?
Why do you like yours so much ?
