Well, my friend ran a 557 for 3 seasons of bracket racing. RAIV cam, home ported 62s with a Warrior and 750 DP on top.
It ran really well, beating my 455 for a bit and he let me know about it.
Then it broke every main bulkhead in the block.
Stock-ish only blocks as far as I am concerned.
He has moved up to a good 400 block with Butler Scat 4" crank and rods with the same heads. Car runs 10.50s now.
